Outlook 2013 asks for credentials connecting to Exchange 2010 multiple times
I'm having a problem with Outlook 2013 asking for my credentials a few times a day for no apparent reason. Some info on my setup...
CLIENT
Windows 7 Professional SP1 64 bit, fully patched
Office 2013 Pro Plus 32 bit, fully patched (has there even been any patches released yet?)
Outlook auto-configured to Exchange during setup.
Online Archive setup with server
Connected via gigabit ethernet on same network and domain as Exchange server.
SERVER
Exchange 2010 SP2, fully patched.
One server, holds all roles.
I have zero clue as to why I'm getting popped for credentials. This did not happen prior to my upgrade to Office 2013. I was previously using Office 2007 Pro Plus.
My credentials are always accepted, never a problem putting them in.
Thanks in advance!

When does the password prompt window pop-up? the beginning of Outlook launching or Outlook is running? Have you configure other email account in this Outlook profile?
You'd better capture the windows of password prompt and post here to get the more clue.
In generally, the likely reason why the password prompt for your Exchange account is because you are enable Outlook Anywhere and the authentication settings have been set to Basic Authentication. Unless you can switch to using NTLM Authentication.
Another reason for this issue is because the Outlook setting is changed after upgrade. Please check the setting as the following screenshot:
In addtion, please create a new outlook profile and test the result.
Cheers,

To answer your questions....
1. The password prompt pops up BOTH when Outlook is launched AND after Outlook is running. Neither always occurs though. Sometimes is doesn't pop upon launch, and sometimes it only pops up at launch.
2. I will capture the window next time it pops up.
3. I have changed the authentication to NTLM instead of Basic Authentication. We'll see if this makes a difference.
4. The check box for "Always prompt..." was already checked. I left it as such.
5. I will wait to see if the change to NTLM authentication makes the difference. If if doesn't, I will screenshot the password prompt, post it here, and recreate my Outlook proflie.
Thanks you for your help. I will let you know either way where things go from here.

Still experiencing the same problem. It's weird that the prompt is occurring even though I'm syncing with Exchange with no problem behind the prompt?
November 26th, 2012 2:13pm
I'm having the same issue. As are a couple of my co-workers. One difference, we're using Office 365 with Office 2013.
We had no problems prior to the upgrade to Outlook 2013.
We are seeing the same issue as Tom...we get prompted for credentials....Outlook is still open and receiving emails just fine in the background.
I can come back after 24+ hours of ignoring the prompt and all my folders are up to date but the window is there asking for my password.
I don't have the "Always prompt" box checked either.
December 4th, 2012 8:39pm
I'm seeing this same error as well. In our environment we have Exchange 2010 SP2 RU 4 v2 installed. I'm one of the exchange administrators for that system. In trying to narrow down the problem it seems related to the downloading of the
offline address book (OAB). At client launch, as well as periodically while open, a full download of the OAB is requested and that is exactly when the prompt occurs. I have verified this also through checking the Connection Status window (accessible
by Cntrl-right clicking the Outlook icon in the task bar.) There is a local mailbox activity tab, that shows a pending OAB download. This message does not disappear until credentials are entered. That's odd, because our Outlook 2010 users
do not experience this prompt. The OAB virtual directory has both Windows/Integrated and Basic auth enabled. For some reason it seems that it's hitting the basic auth instead of the integrated. These are all on campus users, not external
users.
December 5th, 2012 9:02pm
So.....been a month now since this question was posed. Anybody from Microsoft want to take a crack at this?
December 14th, 2012 2:28pm
This is a problem for me also.
December 28th, 2012 9:35am
Actually, something that 2013 did through the set up was to add the details for Outlook anywhere.
I have unticked this (my machine is static) and it appears to have solved the problem.

unticking Exchange proxy settings does not sounds solution for me, because that setting is useful if a user has laptop and wants to connect Outlook client outside office. We are having the same problem for pop-up credentials after upgrading outlook 2010
client to 2013 version.
We have server Exchange 2010 SP2
February 13th, 2013 9:38am
Solution on the client side is to turn off "Download shared folders" wich is in
File -> account settings ->account settings -> Edit.. (account) -> More settings... (button on the bottom) -> Advanced (tab) -> Untick "Download shared folders"
On the server side. Probably you have to create shared folder. Maybe someone could reply link to how to.

Has this anything got to do with certificates?
Maybe sth with autodiscover in certificates? just a hint
March 12th, 2013 3:09pm
Do not think so. Outlook 2007 and 2010 works OK, there is only a problem with 2013 :-(
March 13th, 2013 9:32am
I am having a similar issue, and I can see that it is having trouble with the OAB and EWS paths. (I can see this through my ISA 2006 server) I have tried some of the suggestions from previous post, but they have not worked with the exception of clearing
the Http connection which limits the laptop users.
I have also found that the problem does not happen on systems that had an upgrade from 2010 to 2013, but it happens on systems that have been imaged and Outlook 2013 installed or 2010 uninstalled and 2013 installed.
Has anyone had any luck?
March 13th, 2013 7:29pm
Same here.
The problem happens only on 2013 clients when the client's wants to download OAB.

March 27th, 2013 8:45pm
I am hoping an solution was found by this time, but because I was having a similar issue, and did find a solution, I wanted to post so others get the information.
My configuration is a slightly different (Win 7 and Win 8, Office 365 (for sharepoint and exchange), Office 2013). I went to the account data files and deleted the SHAREPOINT LISTS, which is for the address book and calendars. I believe the issue was a rogue
calendar entry trying to sync and causing repeated credential login requests. With removing the SharePoint list from local computer all login requests stopped. Address book, email, and calendars all were unchanged.
May 27th, 2013 3:25pm
I have been testing and testing also for days, then waiting for any responses to other people's questions on other places as well.
After some time started my own tries again.
Now I fixed my issue - don't fully comprehend it. But anyway here comes the solution that worked for me (and hopefully for more of y'all)...
Go to the Exchange account from within Outlook, click special settings, tab connection. Open up the button proxy settings, UNtick options 3 and 4 (connections with HTTP/then TCP/IP). Make sure to UNtick both.
Press OK, Hit Save and OK again. Press NEXT and close the screens.
Logout from Outlook. LOG OFF your RDP session if you're in one. Restart the RDP session after some 15 seconds. Or start Outlook if you were only in Outlook.
My issue was then solved.
May 27th, 2013 11:18pm
Wouter: "Go to the Exchange account from within Outlook, click special settings, tab connection.", where is that?
May 28th, 2013 6:49am
In our case the solution was strange.
With MS SUPPORT we have tried several things (deleting and recreating virtual directories: autodiscover, webservices, oab...). Didn't help.
After that we have realized that it must be some OUTLOOK 2013 client vs. TMG loop thing (strange thing that this was not happening to Outlook 2010 clients, probably 2013 uses a different way to connect whether the client is inside LAN or not).
In our internal DNS (inside LAN) we had internal A record for OWA which was pointing to DMZ (TMG listener for OWA).
This caused a "loop" and pop-up credentials in outlook 2013 clients.
* After changing internal A record for OWA to point to Exchange2010 IP in LAN,
* Doing redirection for owa.company.com to owa.company.com/owa
The problem for credentials disappeared.
Very helpful links for redirection OWA.
http://hardanswers.net/redirect-owa-exchange-2010
http://www.ehloworld.com/186
http://technet.microsoft.com/en-us/library/aa998359.aspx
We have manage to KILL that nasty pop-up window for credentials inside OUTLOOK 2013 clients. For OWA redirection I recommend you to use Powershell scripts from this site (http://www.ehloworld.com/186).
If you have already done some manual changes for OWA redirection thru IIS on Exchange, double check if other virtual folders have redirection enabled. They must not have it (except for the default web site).
In our case we needed to uncheck it for Exchange folder on IIS, because OWA started to crash.
I think modifying settings on OAB folder were also necessary because of the redirection.
We needed to add Authenticated Users and give them read permission on Exchange OAB folder (Default location: C:\Program Files\Microsoft\Exchange Server\<version>\ClientAccess\oab). (http://technet.microsoft.com/en-us/library/aa998359.aspx).

May 29th, 2013 11:38am
I`ve been losing sleep thanks to this credential problem (asking for password) for a week now. I migrated a client to Exchange On-line (office 365) and two stations have Office 2007 with mutliple profiles. The prompts not only ask for the password,
but the username that popped up was the wrong one consistantly. If I asked for Mr. X`s profile I`d see Mr. Y and so forth.
Thanks to the information above I was able to finally (keeping my fingers crossed it still works in the morning) get the prompt to stop asking. I basically went into the ADVANCED tab (under each account) and unselected to load shared files/Data. (I`m translating
since the outlook was in French). That did it. Now to see what impact this has.
I hope this helps someone.
Regards,
Bob

We also had a different number of PC's with issues.
I have selected under the Advanced tab to SELECT to USE CACHE. Just that, no other ticks.
Waited a bit for Outlook to start syncing, then Closed Outlook.
After a few seconds (giving it time to close properly) started it up again. Then UNSELECTED to USE the CACHE.
Closed Outlook, started it up. No more issues either. Problem solved.
Just for your info - we use the connection while on Terminal server...

I also had a user that after upgrading to Outlook 2013 was continuously prompted for credentials while trying to connect to Exchange 2007 trough Proxy from home (while not logged into domain)
- after I tried most posted suggestions with no luck, I was looking at the mailbox properties and under the account tab I noticed that user logon name was different than the e-mail address, tried that one with the correct password and it connected to
Exchange and did not prompt again; all the other settings were left untouched
- apparently user always logged into her Outlook with the e-mail address / password before

Just had the same issue where Outlook was requesting username / password on startup for a lot of users . Nothing was changed in Exchange, everything was running fine.
Last but not least closing outlook for more than 5 minutes and reopen it worked.
August 8th, 2013 1:45pm
Ok, same issue here. Outlook 2010 works fine, but Outlook 2013 prompts on download of OAB. Meaning..
1. Outlook prompts at startup (or shortly thereafter, usually after 30 seconds or so)
2. Outlook prompts periodically as it attempts to download the OAB
3. You can force the prompt it by selecting "Send/Receive", "Send/Receive Groups", "Download address book"
4. Emails continue to sync just fine even if you never supply credentials.
I can't believe so many have this same problem, yet this remains unanswered this long. Just as others have said, Outlook 2010 works great, so I know there's nothing wrong with Autodiscover or the /OAB virtual directory.
We have a Kemp load balancer in front of our CAS array. I can edit the hosts file to send clients to the CASArray members directly and that does not fix this, so it's not the load balancer.
Using a packet sniffer, It seems as though Outlook 2013 fails to reach the internal URL for /OAB so it attempts the HTTP address, which doesn't support windows auth (basic only for outside). By editing the host file and entering the IP address of the
internal CAS array as the External mail host, the prompts stop. So, for example.
External is mail.contoso.com and is 10.10.10.1
Internal is outlook.corp.contoso.com and is 192.168.1.1
If I change the hosts file so that both are 192.168.1.1 it works without the prompt.
I cannot figure out what it is Outlook 2013 doesn't like about connecting to outlook.corp.contoso.com for OAB download, which forces it to go to mail.contoso.com (and therefore, prompts for authentication).
August 13th, 2013 6:51pm
Hi,
I was facing the same issue with all outlook 2013 clients authenticating against exchange 2010 server.
We have Exchange 2010 SP3 with TMG in place.
I found that the rule on TMG that does web services ahtuentication delegation to Exchange was set to "Basic Authentication". When I clicked "Test the rule", it gave me error on OAB virtual directory with the reason.
The authentication on OAB virtual directory on Exchange server was set to "Negotiate/NTLM". Hence, all outlook 2013 users with RPC over HTTP enabled were being prompted for authentication while downloading Outlook address book.
I changed the authentication on exchange OAB virtual directory to "Basic" (in Sync with TMG rule) and it removed the authentication prompt for us.
hope this helps.
August 19th, 2013 7:04am
My solution was to THICK both "connections with HTTP/then TCP/IP" at the proxy settings tab.

August 30th, 2013 6:21pm
Okay so how do I get to this magical "Advanced" tab? I'm not working in Exchange but specifically in Outlook though it doesn't appear to even be syncing my email so I may just scrap it altogether.
I just want the constant pop up asking for me to select a profile to stop. Is that what everyone is referring to when they say it is asking for credentials. Mine is not asking for a password or anything, just selecting a Profile.
Help a non-tech here....
September 5th, 2013 4:39pm
Yes, this fixed my problem. Now to figure out what server problem causes this so we don't have to make this change on each of our clients.
September 13th, 2013 7:08pm
yeah mate this is an entirely different issue. you need to create a profile in order for it to be able to sync any emails.

Can I ask what is your deployment? We have this issue but with Exchange 2010 SP3 UR2 with Outlook 2010. I have check the OAB / IIS settings, all good. The issue does get resolved when RPC over HTTP is unchecked but our mobile force do not like this! So it
makes me think it may be an authentication issue between Basic & NTLM.
Are there any other updates? Has anyone else implemented the KB above?

Hello.
I have the same problem with Exchange 2010
SP1 + Outlook 2010.
November 7th, 2013 5:00pm
I know this is old and its probably old news and you've solved the problem, but I cant see anywhere that describes this solution. I have the same setup, exchange 2010 and outlook 2013 with windows 8. Everything used to work just fine with
outlook 2010 and outlook 2007, but with outlook2013 its popup credential time. I did all the recommended things, delete profiles, recreate virtual directories etc etc etc. Then something on this page
http://msexchangeguru.com/2013/01/10/e2013-outlook-anywhere/ made me look at the IIS\RPC authentication settings. By default its only got basic authentication (thus the popup I
guess). If I change the IIS\RPC settings to Windows+Basic authentication, lo and behold everything works, http/rpc, https/rpc, no changes on the clients. Internal clients work, internet clients work, all is good with the world.
The only problem is the change is temporary when it is changed in IIS. To make it permanent you need to use the Set-OutlookAnywhere cmdlet.
The option that worked for me was
Set-OutlookAnywhere -Identity 'MyServer\RPC (Default Web Site)' -IISAuthenticationMethod NTLM,Basic
Give it about 5 minutes to kick in and you should see the authentication methods change in IIS
Hope this at least gives someone a heads up.

This worked for us across all clients. Waiting to see if exchange re-sets this as some others have stated it will.

IF you are using outlook 2010! Open outlook - File - Account settings - Add and remove accounts and change ... - Double Click on your exchange account - More Settings - 2nd tab is Advanced.
I was having the same issue. Changing Proxy settings to NTLM seems working. Still monitoring though.
November 26th, 2013 8:33am
This seems to have worked for us also. Our users have access to a VPN from outside of our organization that does the leg work.
November 27th, 2013 3:14pm
This has been the BEST diagnostics I've see and it seems related OAB and IIS. One thing I've noticed is how poorly Exchange handles IIS permissions AND how many administrators have to directly modify IIS to resolve "internal" issues. Still digging for
the setting we need to address, but for diagnostics. Have a CLIENT that is not on the domain connect to exchange from the internal network and see the results. Thanks for this great post and observations.
December 13th, 2013 2:36pm
Nice diagnostics as well...thanks for the great information in helping to get one step closer to figuring out whats going on with Outlook 2013. Sometime I wonder about the dev team in India that Microsoft assigns to these projects.
December 13th, 2013 2:42pm
Nice find.. that is correct. SharePoint Lists were being SLAMMED at profiles even after you removed them, they would reappear in the account settings. This is definitely something think about.
December 13th, 2013 2:46pm
Thanks for the CLUE as to what the issues might be. From your observation, you are letting us know that HTTP is still issue. As stated in my earlier post, it still seems to be pointing to IIS and it's permission settings.
What everyone is wondering is
1. Why does this only happen to Outlook 2013
2. Only happens to NEW installs and NOT upgrades.
3. Seems to be related to connections only involving the HTTP proxy from INTERNAL networks.
Technical Special Note: What makes this all worse now is that there is a major push that WILL happen with certificates. The certificates will ONLY have one domain allowed on them and no longer have internal domains. Making the connectors
fail the HTTP requests. This will mandate major reconfigurations and SPLIT DNS and powershell to get around this. Head aches are coming if these giants don't get on the same page.

I want this fixed because our employees are getting annoyed of this, they can't work when every minute there is a credential popup!
January 30th, 2014 3:15pm
I had this issue too. Turns out the solution was simple.
I didn't think to look, but the username was defaulting to user@domain.com.au and while my password was correct, it would only accept domain\user.
Hope this helps someone with a local domain joined account.

Get-OutlookAnywhere | fl > c:\any.txt
Get-OabVirtualDirectory | fl > c:\oab.txt

Get-ExchangeCertificate | fl > c:\cert.txt
And then I saw in the get-outlookprovider
Name
Server
CertPrincipalname
TTL
EXCH
Notmymx
mail.mydomain.com
1
Why there was an entry for a server that was not one of my Exchange servers, is still a question
But after I blanked it out with
Set-OutlookProvider EXCH -server $null -CertPrincipalName $null
Everything works as expected now.

I experienced this issue on one client site and spent over 12 months trying to fix it. I discovered what
the root cause was last week. The client had installed CCLEANER on some PCs and it was scheduled to run @ 5pm daily. On some PCs it was configured to delete Internet & Network passwords!!. Need I say more? I unticked these options and Outlook stopped prompting.
February 16th, 2015 12:21pm
This also resolved my issue... (Solution on the client side is to turn off "Download shared folders"
wich is in
File -> account settings ->account settings -> Edit.. (account) -> More settings... (button on the bottom) -> Advanced (tab) -> Untick "Download shared folders")
Outlook 2013, exchange 2010... asking for password on only SOME clients (others were fine, same software and setup)
could trigger the ask by send and receieve Outlook address book... have no idea why this worked. But as soon as I unticked... launched Outlook, put password in 1 last time and clicked "remember password"... never came up again!!
