Second time I'm having the same problem with Outlook on Vista Home Premium 32-bit with all service updates as far as I know (machine is an HP Pavilion dv2315nr).
When I open Outlook, initially it shows a notification that "personal folder didn't close properly and is being checked" or words to that effect. Then it ceases ("Outlook has stopped working")with the following error details:

The first time I had this problem, running scanpst worked beautifully (a week ago). This time I scanned and repaired, rebooted and tried again, to no avail.
If reinstallation is the only way forward, I'll do it but would like some advice as to how to do that without losing my current PST--and breaking the next installation if the PST file is in fact the problem. The current PST is 1.36 GB right now. Outlook has displayed some other strange behaviours in the past while, which may or may not be related. I have attached a screen cap of what was happening before the last time this happened (not this time); It was spinning through the send/receive tasks over and over, and the task count kept incrementing as it went, until I killed the outlook process.
On the machine I also run ESET NOD32 antivirus, which is up to date, and Office 2007.
