avast 7 locks up outlook 2010 64-bit

[Lisandro]

What another plugins for Outlook you use?

The toolbar is back again... But it's a weird and erratic behavior... The other addons are in the screenshot.

It appears like this is an issue in my office also but with Windows 7 (64bit) and Outlook 2007 (32bit).  Users are connecting to Exchange 2007 server.

I have some users recently having outlook freeze up on them after attempting to narrow down the issue, I noticed that all of the users with the problem have Avast software.  All of my other users without the issue do not have Avast.

After disabling the avast junkmail outlook plugin it appears so far (it's only been about 4 hours) that the freezes have stopped.  I probably need to go a little longer to be absolutely sure however.

I'll follow up again tomorrow to confirm results.

I'll follow up again tomorrow to confirm results.

Could you try to get a dump from one of the affected computers?
Thank you

do you want an event log entry?

Essentially the users have to "end task" on outlook manually to get it to shut, then reopen it.  It doesn't actually ever crash close.

Appears that the avast junkmail plugin was definately the cause of our lock ups.  All users with the plugin disabled immediately stopped have the problem and have not had a reoccurrance in the last 24 hours.

I'm Administrator on my laptop, but Outlook says I'm not allowed to disable that plugin. Any tips on how to do so?

Yes, this is the normal behavior. The Office executables are not started elevated.
Go to Microsoft Office folder and right click the Outlook.exe. Start it as an administrator.

OK - that did it. Removing the avast spam plugin fixed the problem! I wasted a couple hours un-installing, searching, re-installing, etc.

Now, the toolbar is gone

Avast 7.0 Same problem here Win 7 64 bit SP1 Outlook 2010 + BCM 2010  - keeps crashing locking up outlook since Avast programe update to version 7.0.1426 No problems before this update.
I had to disable outlook Addin
I only use 3 Outlook Addins, 2 for BCM and the Avast one.  The normal Outlook installation or repair loads a lot we dont need that slows outlook load.
Have to use task manager to close outlook
So annoying, please issue a fix pronto!

Thanks

I just purchased Avast last week, ever since my Outlook 2007 locks up and currently I can't even open it.  What do I do?  I have re-installed my Office 2007 software but it didn't help.

I have been experiencing the same problem on my two home machines.  Both began exhibiting the same behavior when installed version 7.0.1426 of Avast.  Outlook would run for a few minutes at a time but then freeze when any email was sent or recieved.

 First I temporarily disabled the avasts mail shield and Outlook worked fine until it came back on ten minutes later.   

Following the information in the previous posts I disabled the Outlook AVAST Spam Addin on both of my laptops.  Both are now working fine. With the mail shield turned back on.  However, I don't know if it's actually doing anything.

Any update on tracking down the root cause of the issue and if/when we will get a patch?
