    Default zdb compaction not compacting

    I had a fairly large zdb file (about 7GB). Cleaned out a lot of stuff into pst files.
    Then compacted. This got the zdb file down to 5GB, not great, so *lots* more cleaning out.

    Now I have Outlook reporting a total folder size of about 300MB.
    But compacting does not reduce the zdb file below 5GB and it returns suspiciously quickly.

    What can I do to get the 5GB down to something that is similar to the 300MB that is actually being used?

    If it's only 300 MB, your best bet is probably to create a new profile and initial sync. 300MB shouldn't take more than a few minutes.

    I think the bigger question is why do ZDB files get so large? I have an 8GB one, trying to compact can literally run for hours and produces not much change, and I've never had over about 400MB of mail - in fact, my COS quota is 1GB.

    This topic exists in several threads but the answer seems to always be "don't have so much mail" or "just start with a new ZDB". Those are not the simplest options for our end users who are starting to show up with 6, 7 or 8GB ZDB files.

    Do we know what the deal is with these things getting so big? Can we avoid it somehow?

    Same issue here!
    Ive activated my BB device for 5 days and the zdb file is already 200mb big. Ive currently 25mails on my BB device and a few calendar entries.
    Yesterday Ive checked the zdb file, it was 186mb big, today it has already 200mb, I just got 5 new mails without attachements over the night.
