Microsoft Office Outlook has stopped working

I’m currently ruuning Windows 7 Ultimate Edition and Office 2007 Professional Plus. I receive “Microsoft Office Outlook has stopped working Windows is checking for a solution to the problem” just about everytime I use Outlook:


Application Event Log Error Message:


Event ID: 1000 Task Category: (100) Level: Error Description: Faulting application name: OUTLOOK.EXE, version: 12.0.6504.5000, time stamp: 0x49e7f47e Faulting module name: olmapi32.dll, version: 12.0.6504.5000, time stamp: 0x49e7f423 Exception code: 0xc0000005 Fault offset: 0x00051a61 Faulting process id: 0xc1c Faulting application start time: 0x01ca340a023dfe6b Faulting application path: C:\Program Files (x86)\Microsoft Office\Office12\OUTLOOK.EXE Faulting module path: c:\progra~2\micros~1\office12\olmapi32.dll

Unknown. I have run “outlook /cleanviews” and scanpst.exe on my pst to fix all errors that were found with it. I am still experiencing this problem. If anyone has a solution for this problem, please comment.

Update – May 17th, 2010
After receiving the error “Outlook experienced a serious problem with the avg exchange extension add-in” and disabling the plugin,  I no longer experience issues with Outlook.

    I’m afraid all I can report is that Microsoft Server 2008 R2 has the same problem with Outlook 2007. It’s looking like this is an issue that requires a hotfix from MS. I’ll let you know if I find one.

    Hi, have only JUST experienced this exact error.. Outlook was working fine this morning, however.

    Prior to it appearing (15mins ago now), my system CRASHED, though I believe it was a faulty (old) power cable, as I’ve since replaced it and re-started. Twice.

    I’m not aware of any other auto-updates which may have applied, and didn’t think before asking AVG to scan for updates (as now I can’t see when the last update occurred specifically, though it’s set for Auto every 4(!) hrs), but it reported there were no new updates anyway.

    I’ve TaskMgr-shutdown Outlook twice as it ended up “(Not Responding)”.
    So, now that the ‘avg exchange extension’ message has come up more than once, I feel *inclined* to disable it as suggested.. except I’d rather not, until I know what I’m disabling, and what might happen.

    I’m reading this thread next:

    Haven’t yet found anything AS SPECIFIC w.r.t. this..

    Good luck with yours!
