How can I reduce my huge (>6GB) Outlook 2007 pst file size while using IMAP?
Posted on 2009-04-21
I use MS Outlook 2007 and recently had issues with my pst file not closing properly. Now, the dreaded "gears" icon in the lower right corner is seemingly permanent, saying "Data file check in progress." I've found a lot of information on what might have initially caused the problem, and have implemented some fixes, but I don't know if the fixes are working because that gears icon has never gone away (it's been days now).
I assume this is because Outlook is trying to complete a scan of the pst file, which I just realized is over 6GB! I see posts all over saying that anything over 4GB creates significant performance issues (although I'm not sure if this is still true with the latest software updates?).
I'm just looking for more information on the topic, and to learn if a 6GB is actually a problem. If it is, I use IMAP email, and would like to keep my entire inbox on my laptop at all times. How can I lower my pst size while keeping years worth of email accessible from Outlook?
