i have outlook 2010 in windows 7 64 bit. For 3 weeks now I have had to run SCANPST numerous times each day to remedy errors, sometimes as many as 5 or 6 times. Only to have outlook crash again an hour later. I run SCANPST again, maybe only a few times this tme to remedy errors that now exist. If I run the SCANPST the next day I have to run it at least 4 times to fix errors. What am I missing that this cannot seem to be fixed on a permanent basis?

Based on your situation, I high recommand that you create a new pst and copy all of items into the new one.

If this isn't a PST file but OST, just delete the previous one and re-sync it from Server to solve the problem. Thanks.
