Purging Deleted Mailboxes, etc

I am running Unity 4.03 with an Exchange message store, not Unified Messaging, installed by and not well documented by a consultant in another state (don't ask...). The consultant supposedly set the system up to be somewhat self-reliant, and all we have done is add/remove users with the web based admin tool. I recently logged in to see what kind of space my 300 users are using, and to my shock I found that the database is huge - over 75 gb! From the Exchange system manager I found that some of my top users had over 3000 objects in their mailboxes and were using over 3gb.

I checked with a number of users, and none of them had more than 4 or 5 messages in their inbox.

I have looked all over and can not seem to find any way to purge the deleted items, where I assume the messages reside.

On a side note, I also noticed that the mailboxes of users that have been deleted from Unity still exist in the ADS and are taking up space in the message store.

Is there something I am missing here? I ran the MSM took and scheduled purge jobs, but the results are always empty. Should I call TAC?

Re: Purging Deleted Mailboxes, etc

Couple things here...

1. Yes, when you delete a subscriber in the SA we only remove the Unity specific properties off that subscriber in AD - we do not delete the AD account or their mailbox. You can delete them directly in ADUC.

2. I'm n ot sure what you mean by "the results are always empty" with MSM - I'll need some more details on which job you created and ran. It should be capable of emptying the deleted items folders for you. As a side note, check for the latest version of MSM here:
