Alphamonkey · 02-27-2008, 11:59 AM

I start up my outlook and it will not read my .pst file, and i get an error like this:

I read on another forum to run the scanpst.exe. I run this and i get this error message at 9% in phase 1:

the log reads:

It looks like your problem is being caused because the pst file has reached 2 GB (which is the size limit for pst files in office). I am not sure how to get past the problem, but you have to archive part of the file to a different pst if you are to continue using outlook without corruption of the pst in the future. Monitor the size of the pst file and try to keep it below 1 GB if possible.

I believe it was only versions prior to 2003 which had the 2GB limit - see here

What I would do is check the hard drive for errors before you run scanpst. To do that, click START>COMPUTER, then right click on the C: drive, go to TOOLS, check for errors. That should resolve any errors that you might have on the drive, then try rerunning scanpst.

Thanks for the link, Glaswegian. It looks like they have confused the issue further by making some pst files have the limit and others not. I think it is still a good idea to limit pst file size to under 2 GB because it is difficult to figure out whether it was created with outlook 2003 or was created earlier and imported into 2003 and then into 2007.

Something which you could do (although is a little bit risky).

Change the first 8 bytes of the .PST file to 0's using a hex editor (use something like Winhex). Once you have done this save the file and then run scanpst.exe on the file. This should repair your PST file - it is also likely to recover deleted stuff from your PST file so don't be too confused by that!

Just to make sure that you don't completely mess up your PST file I would recommend to take a back up prior to the above.
