Hi,

There is no such known issues with Outlook 2013 delaying new emails. Hence I feel that there might be something which we are not able to find out. Here I would suggest you to open phone support case with Microsoft as we would like to take dumps and traces to figure out what exactly is causing the issue. Unfortunately this is not possible via this FORUM support and hence asking you to open phone support case with Microsoft.

To open phone support case with Microsoft, please contact customer central on 1800-936-4900 or alternatively you may also go to website http://support.microsoft.com/oas to create a phone support incident

Once we have your case, we can dedicate an engineer to look into the issue and troubleshoot until the issue is resolved.

Hope this helps.

Thanks

I can tell you that it was happening with Exchange 2013 CU1, then it went away with CU2 and now it has comeback with CU3 but hey, at least I was FINALLY ABLE TO MIGRATE 2010 PF's over... I really hate Microsoft this month and last month.

If I switch to Online Mode, the issue corrects itself. No plugins are installed to Outlook, and this happens on clean installs of Windows with only Office 2013 installed, so no background conflicts either... unless Windows itself is a conflict, which I doubt. No third party antivirus, etc. is installed either.

This is purely an issue with cached mode on Outlook 2013. Unfortunately, I'm not able to test with Exchange 2013, but my Exchange 2010 install is current on updates, and as stated in the original post there are no issues with Outlook 2010 clients running in cached mode.

I ran into the same issue and nothing I did seemed to solve it. Outlook 2010 had no issues but with Outlook 2013, major lags. I would do a search and as I clicked emails, I would have a delay displaying emails. As you mentioned, disabling cache mode would solve it. I then remembered something when I was setting up Outlook 2013. Outlook 2013 has the option to limit cache size and defaults to 12months. I just went in, adjusted the cache size settings to ALL from 12 months. (Basically run at full size). No more issues with cache and speed. Worth a try for you!

Hi - I am experiencing the same issue with Outlook 2013, except it doesn't matter if I am in Cached Exchange mode or not - no difference. Outlook 2013 is terribly slow at opening ANY email. Every time I click on an email (either to view in the Reading Pane or double click to open it) - Outlook hangs for around 20 seconds and displays "Outlook is not responding" in the title bar.

I am on Exchange Server 2010.

At this point Outlook 2013 is unusable as a product. I have thousands of emails all carefully filed away and right now it takes forever to open even a few of them. Going back to 2010 for now.

We have had a few problems with Outlook 2013 (Exchange 2010), mainly with slowness issues. Outlook 2010 worked without issues however with Outlook 2013 emails on my iPhone show up instantly but were delayed in Outlook 2013. I tried the Disable Graphics Hardware Accelerator, which may have helped however the big fix was with caching.   I switched to No Caching mode and found a bunch of old emails in my Outbox and several other old emails in other folders.  I got all these back in sync to the current date, once I did that, I enabled Caching mode and once the cache was rebuilt everything started working properly.

Not sure if this helps but we disabled the add ins in outlook options area.

Disable any and all sharepoint and business connectivity services.

I have been reading the mail so to speak on this thread, and even after reformatting my drive and reloading win 7 x64 and office 2013 --  i get email notification on my iphone at least 30 seconds or more before it shows up in my outlook accout - active sync -- i believe my company uses 2010 server.

I have a Windows 8/8.1 system with Outlook 2013 connected to an Exchange 2010 server via Outlook Anywhere. Inbound emails will often take a significant amount of time to appear in my Inbox. Using Outlook 2010 on the same system is near instant. I've already tried uninstalling/reinstall and no fix. I've tried disabling Graphics Acceleration and no fix. It is NOT a network or server issue as ALL clients connecting via Outlook 2010 and Active Sync are instant and several test systems with Outlook 2013 all experience this issue. Even Windows Mail on the same client will alert immediately.

The precise symptom is that someone sends me an email... Outlook 2010 and Active Sync clients will alert immediately, and Outlook 2013 will take up to 30 seconds to update the Inbox counter and listing to show the message/alert.

This issue is making Outlook 2013 nearly unusable for me, and I cannot begin an enterprise rollout of Office 2013 until I find a resolution.

I've had similar issues as well.  It all began when I upgraded from Office 2010 to Office 2013.  Immediately I noticed interface lag in all of the Office applications due to the new transitions that are applied in various menus.  I wrote this off as just poor design, but most recently I've been having the toast notifications in Outlook popup sometimes up to ten minutes after the e-mails have arrived (and in many cases already been deleted or replied to).

My fix is running Outlook 24/7 on one monitor.  The notifications are unreliable.

My company is having this issue as well. We have not moved to Outlook 2013 site wide yet but most of the IT staff is running 2013. Our exchange server is 2010.  None of the above suggestions have worked. Even starting with a clean computer and fresh install doesn't help. My phone receives email about 15 seconds to even a minute earlier than Outlook 2013 on the computer. Once Outlook 2013 shows the popup for the new email it takes an additional 5 to 15 seconds to display the email in the inbox.

Hopefully someone finds a solution because I have been digging for a while now.

i am also having this issue. i cannot believe it i was running vista with 2007 outlook. now i have windows8 and outlook office 2013 and it is crap. 2 sent items for every sent item. Delay in inbox notification.

I am not an expert but there is clearly some problem in trying to make an end user system act like a webmail and then use this end user system to synchronize the folders between the host and final destination. I am pleased I have found out as our organisation was also due to update.

I have looked through microsoft user sights - they are kidding themselvs - none of the techs have any idea

I am having this very same issue with a fresh install of Windows 8.1 and Outlook 2013.

It occurs with Hotmail/live service and Gmail service.

So yes, there is known issues with Outlook having this problem.

This is not an "answer"

I'd like to add that we are experiencing this same issue. I receive new emails to iPhone at least 30 seconds before they show up in my Outlook 2013 Inbox. Issue does not occur on Outlook 2010 clients. Affecting multiple systems.

I've tried all the recommended "fixes" on here with no results. I don't think the provided answer is acceptable, since this is obviously affecting multiple users. GoodThings have you opened a case? If you do, can you please share the real answer with the rest of us :)

Exchange 2010 Server

Windows 8.1 x64

Outlook 2013 32-bit

This is a strange bug indeed. However I have noticed if you open the message by clicking on it in the message list pane, the message will not only open in a new window, but will instantly download in the new window, and in the reading pane.

I guess Since this is classified as "answered" time to open a new thread.

Like many of you on here, we are having the exact same issues. Running Exchange 2010 SP2 RU2, a clean install of 8.1, a clean install of Outlook 2013 and there is a 5-15 second delay clicking through e-mail, changing folders or moving between Calendar and Mail. Outlook 2010 with Windows 8.1 had ZERO latency with any mail navigation. I'm not running cache mode either, we only have Outlook 2013 deployed to a few admins because there is no way we are pushing Outlook 2013 out until Microsoft finds a fix. 

Note: all of the recommended "fixes" did nothing for us either. Judging by the amount of Admins reporting this issue I'd say this needs to be reported to the Exchange Messaging team for a resolution if they want Outlook 2013 used. 

Your phone support is a waste of time. They always ended up saying that it is the providers problem and they cannot help.

We have the same problem with two of our customers. Two different Exchange 2010 SP3 servers with Outlook 2013 Clients on Win8.

I'd be glad if Microsoft is able to reproduce the issue and find a fix for the problem!

I'm experiencing the same issue.  I'll hear the new email notification alert on my phone and often 30 seconds later the email appears in outlook.

What is even more unusual but I haven't seen mentioned is, at least in my case, often the unread count beside inbox in the side bar will increase right away, but the actual email won't show up in the message list for 30 seconds.  So it is seeing that there is a new email but not actually displaying it for a while.

I was on outlook 2010, never had any issues, upgraded to 2013, now I see this on most emails.

Which cache settings do you use? (3 months, 12 months, all, ...)

Is the mailbox connected to multiple computers?

Does it work in online mode?

Would be _very_ _very_ great if microsoft will start trying to reproduce this problem and stop with their stupid head-in-the-sand policy!

Identical problem here as well.  Exchange 2007 (fully patched), Windows 7 and Outlook 2013 cached.  Brand new admin computers, and we're all experiencing delays.  Emails arrive on iPhone, Android and Blackberry well before arriving in Outlook.  The delay is usually around 5-8 seconds, but sometimes up to 30.  Regardless, 1 second is too long in this environment.  I've tried disabling graphics hardware acceleration as well as the firewall completely.  Outlook 2010 works fine.

That is not the issue either. If you double-click the message in the message pane, it will bring the message up in its own window. The message will immediately be displayed in its entirety.  Which means it is probably a coding bug, not some setting affecting it.

Exactly same configuration and same problem. Did not found any other solution than disabling Cached mode which is not acceptable as I'm travelling a lot. What's up Microsoft? It does not even work with Gmail/Hotmail and other accounts.

Firewalls and other security tools disabled, no add-ins in Outlook 2013, everything updated, clean install, Outlook profile created from scratch.

I hope that it will be resolved soon.

Try this:

File > Options > Advanced and check Disable hardware graphics acceleration and restart Outlook 2013.

Just tried the disable graphics acceleration and restarted.  First email that came thru was delayed per usual, so that did not resolve the issue.

I completely agree with you. This issues has nothing to do with Firewall or environment. 

Simply a shortcomings of the Outlook 2013 , however i have seen Outlook 2010 with the same issues. 

Calling support makes no progress, since their advise is to re-create the Outlook profile, which only works for a short duration then back to square one 

So , 

i understand , no one has found a long term solution for this issue ? 

Agreed with both posts !

The only "solution" is a workaround - to disable cache mode -> then everything is working as expected.

Even when not in cached mode, I would receive a notification when a new message would arrive and the new message number would increment next to my inbox, but the message would never appear in my inbox until I went to a different folder and would come back. I finally discovered that this would happen when I have my outlook set to group / sort by categories and then Receive date. If I click on the receive column so that I am only sorting by that column then the messages will appear instantly. Obviously a bug that Microsoft needs to fix.

Yes and a big YES...i am having this problem for months now.  And who says "there is no such issues"...

Its really disappointing for Microsoft to provide such backward application.

PLease fix it or admit that you guys are not able to understand our problems. Then i shall give up trying to install uninstall config and reconfig my mailboxes.

Is anyone able to reproduce the issue? I'm not absolutely sure, but I don't think that the sort order was changed where I've seen the problem the last time (because it was a fresh outlook-installation with a fresh profile)

We have the same issue here.  320Mb downstream, so not a speed issue.

Outlook 2013, all patched up, on Windows 8.1, all patched up, connected to Office365.

Here's a timeline:

1. Message shows up on my iPhone (connected via WiFi or GSM, doesn't matter)
2. 10-30 seconds later, message shows up in my Outlook inbox
3. 10-30 seconds later, message preview pops up.

This is really unacceptable and we need some action.

I have the same issue. My outlook 2013 email accounts sync so slowly. It's not even worth using outlook as my default email software.

I have these issues too. I have a Surface pro 3 and the email app has always been lagging/not syncing in a timely manner. It's not reliable for checking email. It's pulling email from both my Gmail and Hotmail accounts. Sometimes it'll say that it's been synced when I know it hasn't because I can see in my Gmail account new messages not showing up in the Outlook email app. And when it pulls messages it's sooo slow!

Well after months of troubleshooting and finger pointing, we've resolved the problem we were experiencing.  Disabling the Symantec Endpoint Protection Outlook Add-in did the trick.

Hi,

I am Chetan Savade from Symantec Technical Support Team.

Sad to hear that SEP outlook add-in was causing this issue.

Symantec has released new version of Symantec Endpoint Protection.

English versions of Symantec Endpoint Protection 12.1.5337.5000 (RU5) is now available to download on FileConnect. I would request to test the outlook performance with this version.

Best Regards,

Chetan

Well op3No2 ...did you have the opportunity to down load and incorporate the change ?  Did it work over the 'long haul' and survive th 'updates'? Inquiring minds want to know of your success ... 

That fixed mine

Thanks!!

I have the same problem, taking forever to sync my Hotmail in Outlook 2013, something which went quite fast in Outlook 2013 just weeks ago on my old laptop (using the same connection). Are there any other solutions, as I do not have Symantec and the above does not work... all settings are automatically selected by Hotmail, so little to choose or change. It downloads mail sporadically in batches of 20-30 (small mails that is), but like this it will take me 1 month to get all my mails...

Will it help if you turn off message preview in Outlook 2013?

View tab -> Message Preview -> Off

This has resolved my issues with outlook 2013 caching again Exchange Online.

http://www.expta.com/2010/10/how-to-configure-fast-cached-exchange.html

The cache timer is 30 seconds, this reg hack reduces it down to 1 sec.  

In the bottom left check 'Folders' and look in your Mailbox for a folder  called 'Sync Issues'.

The items are really helpfull in determining the cause.

I had an issue when using cached mode. I had a number of additional mailboxes active in my account, and all of them were cached. (advanced tab)

This resulted in a huge (4.5GB) OST file, and very slow respons.

And the number of items cached was so big, that it hit a limit set to the amounts items cached.

As a result, items were cached as other were deleted....

(status bar showed last update more than an hour ago)

hope this helps.....
