I have been trying to free up some space on the Exchange Server. Last week, I used Message Store Manager to move a lot of messages (about 300 MB worth) to Deleted Items folder, and I ran the scripts to "Move Messages from Unity Dumpster to Deleted Items folder" and "Flush Messages from Deleted Items Folder".
However, when I go and check the disk space on the Exchange Server, there has been NO freeing up of space on the Exchange/MBX partition.
I don't understand why all of this space is being taken up. There are only 340 mailboxes, and they are using up 16.6 GB of space. Of all the mailboxes, only a few are using > 10 MB. Any ideas on what is taking up all the space and how to free it up?
