I am in an exchange 2007 environment, an have many users who abuse email ( never cleanup or delete messages). We have noticed that our database is about 85 GB and whitespace was about 7 GB after an online defrag ( checked event 1221 in app log ). The past few days I have been cleaning up mailboxes and reducing some mainlboxes from 1 GB to 50 MB.
After last nights backup and defrag I was hoping to have a lot of whitespace in the database.
It seems whitespace is now only 5.6 GB .
It seems that the online defrag is completing ( im seeing numerous event id of 701 in the app log )
Maybe I am not understanding white space and exchange databases. .
I understand that the database will not shrink until i do an offline defrag, but i thought that the amount of whitespace should be increasing as i remove messages from users mailbox.
Where am i going wrong ???
