WIndows 7 and Outlook 2007 - Cannot Connect via RPC over HTTP
Any advice on getting Outlook 2007 (running on Windows 7 beta) to connect to (hosted) Exchange 2007 using RPC over HTTP. Setup seems to go well but I'm unable to authenticate to the server. I suspected IPV6 but have disabled it on the network adapter. Thanks.

Have you tried in using the following logon format: domain\user? I think this should work.Peter Forster, MVP Virtual Machine, Austria

Yes, Vista 64 with Outlook 2007 works fine. I'll try adding the Domain to my user name. Since it's a hosted Exchange provider I need to try to figure out what the Domain is.

What is your email address? If it's myname@domain.com then you would authenticate with domain\myname.Kerry Brown MS-MVP - Windows Desktop Experience

The UPN name has always worked under Vista. I'm wondering what changed?? This would be very confusing to our users who have been told to use their e-mail address.

We use themessagecenter.com as a hosted Exchange provider so I think I need to get the domain that's tied to the hosted service (and not ours).

You must use domain\user, for instance I use sherweb for my hosted provider, their domain name is ihostexchange.net and I use this along with my sam account name which is available in their control panel.For Sherweb therefore the format is "ihostexchange.net\[sam account name] "The trick is to figure out the hosted exchange domainname, Itis not necessarily your own email domain as it would be if you or your company were hosting the service yourself dflood

I'm hoping that someone can help me figure out what the correct domain name is for my hosted provider "themessagecenter.com". Note that this domain does not work and they do not seem willing to provide it (something about Windows 7 not being supported and that there should be no need to enter the domain name as part of log on).Thanks,Paul

I am trying to configure this but I am not sure where to enter what. I am following the steps herehttp://support.sherweb.com/showfaq.php?idarticle=198&idcat=1#At what steps do I enter the ihostexchange.net\sam account name. And when I go into Sherweb's control panel it lists the name with the rg cut off of the .org on my domain. Is this just truncated? Should I add the rg or leave it off.Kevin

On my account on Sherweb the sam account name is a truncated version of my email address for instance david.flood@mycom.co.uk becomes david.flood_mycom.co Sothe full domain\username entry is ihostexchange.net\david.flood_mycom.co This is entered in the windows pop up username and password box during setup and at each login later.Hope this helpsDaviddflood

I also use Sherweb as hosting provider and it works fine with Vista, XP, Server and every user on my network works fine, but Iam use windows7 and I am the only one that could not ccess to the email account through Outlook. uan

I solved this problem using the above mentioned solution, instead of using user@domain for my username I switched to DOMAIN\Exchange_ID and it worked just fine.

For SherWeb user (like me) you can follow thatnew FAQ:http://support.sherweb.com/showfaq.php?idarticle=319Sam account name is the email, truncated at 20 caracter, and @ replace by _Works fine for me!

this may sound dumb but are you sure you have the mail servers certificate installed in your new windows 7 installation?
January 24th, 2009 2:47am

I'm the OP and I too was able to get RPC to work using the domain\Exchange ID format once I found out that themessagecenter.com domain is named "shared". -PFM

David, I also have an account with Sherweb. I followed your instructions and also theWindows 7 instruction sherweb posted on its support site to no avail. Below is what i tried, am I missing something? Your method:ihostexchange.net\kanji_kanji-d.com Inputted this under the Microsoft Exchange Settings window in Username field and in the windows pop-up.With this method i get the following message: "the action cannot be completed. The name cannot bematched to a namein the address list." Sherweb Win7 Method:IHOST\kanji_kanji-d.com Inputted this under the Microsoft Exchange Settings window in Username field and in the windows pop-up.With this method, It does not take my password , the pop-up window keeps on asking forit. Yes the passwordis correct since i have tried it under OWA and the control panel. Could it be thatI have a hyphen in my email.Tech support mention something that Win7 beta does not recognize@.Thanks. Kanji

Got it to Work!I just spoke with Sherweb and the agent was very helpful in getting this to work. We tried first the method which was posted on their site. That didnt work. What he suggested I do was to place my regular email address in the first field when entering my exchange settings. Then once I pressed "Check name" and the window pop-up appears asking for my information, I enter IHOST\SAM_ACCOUNT_NAME. That worked liked a charm! He mentioned that for some users the Win7 instructions posted on the site work fine, for some others, this method works. Below are the examples:Exchange Settings Window: kanji@kanji-d.comSecuirty Pop-Up window: IHOST\kanji_kanji-d.comHope this helps anyone elsethat isexperiencing this issue.Kanji

Is anyone with Mailtrust? Their technical support is not as helpful as Sherweb I guess -- I can't figure out what the "DOMAIN" part of the login would be?Thanks,Peter.

So don't follow the Sherweb FAQ on this address: http://support.sherweb.com/showfaq.php?idarticle=319# Step 7 is clearly wrong: use the kanji@kanji-d.com format as stated above. In the outlook pop-up, step 15, use the IHOST\kanji_kanji-d.com format. I drop Sherweb a line if the FAQ could be changed,it's good to have the Microsoft forums to keep you going on testing Windows 7.
