Hi Your database EDB file will expand automatically until the space on the disk is used up. The ways to increase white space would be to shorten the deleted items retention time, purge disconnected mailboxes and any soft deleted ones. Cheers, Steve

No problem. White space is created when items are deleted or moved out of the database and it allows new data to be written before increasing the size of the EDB file on disk. If you have 160MB of white space in a 1024MB EDB file then you can write 160MB of new mail while the file size remains 1024MB. if you write 200MB (when you have 160MB of white space) then the EDB file size will grow to 1064MB. If you have 0MB white space then then the EDB file will grow as soon as any new data is added. If you have no free space left on the drive then your EDB file will fail to grow and the database will dismount. Cheers, Steve

Try emptying users' "deleted items". You could free up GIGs just deleting those items.

There is no reason to manually increase whitespace in an Exchange database. Mike Crowley | MVP My Blog -- Planet Technologies

You should not be worried about white space, rather focus on how much available disk space you have where you store your databases on. When there is a whitespace on the database, Exchange will re-use it and when there is none left, the database will continue to grow as expected and if you do not have adequate space to hold the database, eventually due to insufficient disk space your database will get dismounted. Hence, placing HD monitoring on MBS server, for available space etc. does have value and will help to keep service continuity.
