Outlook locks after running for hours/days

Please refer to this question. The problem I described several months ago was solved by running the repair option of scanpst. However, in the last two weeks the same problem has begun happening again and is now happening multiple times per day.

Symptoms are exactly the same -- the dialog boxes I pasted into that question are the ones I'm seeing again. However, this time scanpst doesn't solve the problem. Rebooting the system restores Outlook to operation -- but only until it locks up again.

I appreciate any suggestions. BTW, the pst file is 5.2GB.

Check for any Drive HDD issues ... or could even be if the size gets too large.

If its Outlook 2003 than you need to work below 2GB ..... even as Outlook 2007 and 2010 has larger specs but still if PST gets large possible chances of corruption .... i have my PST's around 3-5 GB and then get a new one to avoid issues.

However if you could share some more information (Outlook and OS version?).
Also if you have AV try to have exclusions for the PST file as it gets continuous update it sometimes scans and PST could possibly get corrupted :( (Have seen this many times)

Try the following (based on the linked post):

1. Only check one account automatically. Check the remaining accounts manually (Send/Receive) as desired. The point of this test is to see if checking multiple POP3 accounts automatically is the issue.

2. From some google searches:  If you remove the ACT! address book, Outlook no longer locks up when the alarm window pops up. ... Version Reported: 2011,2010,2009,2008.

3. Also from a google search:

There are some useful comments in this link.

4. Your PST file is very large. Consider archiving it to reduce the size of the PST file. Archives are kept locally alongside the PST file and are easily accessed and searched.

Thanks for the suggestions. My fault for forgetting to include version info:
Windows 7 SP1
Outlook 2010 (14.0.6112.5000 32-bit)
I'm in the midst of archiving old folders to reduce pst file size.

It seems that your PST file is not very large, but has some problems.

One solution is to make a new PST file, and then copy all the contents in the old PST file to the new one, to eliminate all possible errors in the old PST file.

Sorry for not being responsive -- I've been away.

Given that I have opinions above that a 5 GB PST file is both "very large" and "not very large" I guess it's a fairly normal size.

I have been running for the last week with Outlook disabled in ACT and Outlook didn't hang but 1) I was on vacation and the PC was snoozed most of the time, and 2) I can't run that way normally because the integration between ACT and Outlook is business critical.

I'll keep monitoring the situation.

BTW, thinkpads_user, I looked at your links but don't see anything directly relevant: I'm not using Outlook calendar events so that's not a factor; I doubt that AV is an issue because I've been running this version of Outlook and ACT for at least a year and the problem is intermittent; I haven't tried checking just one account automatically for the same reason -- I've been checking multiple accounts since day one.
