Mailboxes Size in Exchange System Manager do not match the size of your Priv EDB file?

Neither did mine….

No matter how many times I defragmented the private information store file, which had hit the 16GB limit, it did not shrink much past 15GB.    This did not make sense, as totalling up the mailbox sizes in the Exchange System Manager came to about 8GB.

What made this even more confusing was the fact that I knew that mailbox retention policies could cause this.   But I had just removed them…   from 30 Days down to 0.   Still, no luck…

So, I walked away, and came back today….   guess what…   it now compresses / defragments.   I assume that exchange schedules itself to get rid of the deleted retention items….   I must find myself an Exchange MVP to figure this one out 🙂

Roll on Exchange SP2!   Increase from 16GB to 75GB!   However, I am still hearing that this increase on SBS2003 will require a patch…   something that I and others are not too happy about.  I, for one, will be bringing this up at the MVP summit at the end of the month.

    Hi Nick,

    You must wait for online maintenance to run in order to get rid off those deleted items.

    There’s a great post by Jeremy about this:

    Excellent! Thanks Rui.

    So, is there a way to force this to happen… and even monitor it happening?

    Well, you can re-schedule the online maintenace so that it hapens sooner, but that can have an impact on performance. My advice is to leave it unchanged and wait for the next day.

    If you reach the 16GB limit, you can temporarily increase it by 1GB:

    i have noticed that the sizes reported in the System Manager do not add up….so i checked out a hunch….and was very surprised!!!

    if you move ALL of your mail from the Inbox to a subfolder – the System Manager reads the size of your mailbox as 0!!!! we use many subfolders and due to this it seems we have gone over the 16GB limit when it was being monitored???

    any ideas??
