Outlook PST File Size Problems

Based on my first open Tech Topic, here is a good page to study intently if you're having problems with Outlook reaching the 2GB size limit on a PST file size. I would also mention to all outlook users that they should run SCANPST.EXE regularly. It's the Inbox repair too, (there's also a SCANOST.EXE for OST offline storage files).

SCANPST.EXE is installed by default to: "C:\Program Files\Common Files\System\Mapi\1033\SCANPST.EXE"

Update: My pal Joni has some advice as well. She's blogging in the Blogathon for Adopt-A-Cat of Houston. Make sure to visit her today.

Is this just an Outlook problem or does it apply to Outlook Express as well? I have the former as part of my Office Suite, but decided I didn't like it as well as the stripped version.

Just Outlook. Outlook Express has a compress function in Tools|Options|Maintenance. It doesn't address corruption though. I think there is a 3rd party repair tool. If I find the link I'll update the post...

If you really, really need to get back lost mail from your PST you might want to contact these guys: http://www.mjm.co.uk/pst.html it costs a small fortune though ($$ per mb). Unless you're a business it's probably not worth it though.

If you are getting close to the 2gb limit you might want to try using something like PSTCompactor (http://www.PSTCompactor.com) which can compress your attachments, etc and then FORCE outlook to compact the mailbox.

We used it here at my work and recovered just shy of 27% thru the company... our CEO's mailbox crunched down from 771mb to 75.4mb (I KID YOU NOT!).

One last thing, Outlook 2003 has a new PST file format you can 'upgrade' to that removes the 2gb limit. I have seen google postings about increased corruption in other areas though so just take care,and backups, it you switch over.
