Determining Free Space in an Exchange 2010 Mailbox Database

In Exchange 2010 you can see how big your mailbox databases are, and how much white space they have, by running the following command in the Exchange Management Shell.

[PS] C:>Get-MailboxDatabase -Status | ft name,databasesize,availablenewmailboxspace -auto

In screen-cap database AB is 64.76 GB in size but has 11.97 MB white space due to mail deleted. This is a nice clean server post migration.  As time goes on the white space will grow and the need to defrag will be required to free up unused space.  — this I will go into at in another post.
