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.

Having public specifications for the ".pst" format, or more accurately, having open tools to parse ".pst" files would be a blessing for many sysadmins.

PSTs are a headache. Not only they continuously increase in size (because users never "compact" and the automatic compacting seems to be a myth) and numbers, but they change just by opening them, which does wonders for the backup systems.

Pain in the neck they are.

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.
