Microsoft Exchange - Random Machines Not Updating

Posted on 2012-09-21
Last Modified: 2013-01-30
We have :

50 Users / 25 Terminal Users

2008R2 - Terminal Server x 2 (brokering)
1 x Microsoft Exchange 2010 Server (CAS)
1 x Microsoft Exchange 2010 Server (Mailbox)

We have at random intervals computers that are not updating without pressing Shift+F9.

The exchange CAS server logs are clean and there is no connection issue out of the ordinary, when they press Shift+F9 everything goes good, but it automatically would not come through.

Most of the clients are 2010 - 14.0.6112.5000 running RPC over HTTPS.

I have tried :

- Headers Only
- Full Items
- Deleting / Compacting OST
- Reinstalling Microsoft Office

It is very intermittent and seems to happen only on random computers.

It says down the bottom "last updated 21/09/2012 @ 12:34pm" so it doesnt say "All folders are up to date".

The user could login the next day and everything would be 100% fine, so it is an annoying one.

The exchange servers are both running SP2, i can get the actual version if this is required.

Would appreciate any help.

    To add, we have workstations running XP/7 that this also happens on. Any advice would be much appreciated.

    Are the user in cached mode or online mode.

    Install the latest Outlook 2010 hotfix as that sorts out quite a few sync issues:

    All users are configured

    - Cached Exchange Mode
    - Full Items

    The reason i have opted for cached is to reduce the amount of traffic downloading on the network, some user mailboxes are large.

    I will apply the hotfix, however this issue only started recently and seems to apply on different machines, different O/S, different hotfix/application levels on the workstations/terminal servers so i am skeptical if it is an issue with the workstations.

    To add, there is an ESET plugin that has been recently installed / updated on the workstations / computers.

    I didnt think this would be the issue as i would imagine it would cause more common errors, i was going to remove the plugin and see what happens.

    Any more advice would be appreciated.

    Try "outlook /safe" and if that works then try "outlook /noextensions". If the /noextensions works then you know an addin is causing the issue.

    The issue was not resolved. Server was reloaded and this seemed to resolve the issue, so it was definately something server side.
