Microsoft Anyone who has ever dealt with Microsoft Outlook will know the .pst file format - it's the binary, undocumented file in which all data from Outlook is stored - emails, contacts, calendar, you name it, it's in there. Microsoft has announced that it will release detailed technical documentation on the Outlook .pst data format.

I spent some time last week moving past year's email into PST files on a user's machine. They retain access to older email and I don't have to store it on the server. The user also doesn't have to sit through long resync times for that multiple-gig sized data blob.

In this case, I was watching the targeted PST file size go down to get an idea of when I could come back to compact the next in line. I noticed the size of other PST files was decreasing as well.

This seemed most prevalent when compacting a file or during the pause at it's end and my return. When Outlook was sitting unattended without a options box open, I didn't see any file size decrease. I can't confirm what the event trigger is to cause Outlook's automagic compacting. I have seen Outlook compacting files other than the one specified though.
