Hello,

I am backing up one exchange server to a tape. However the tape got full recently. How can I check the exact database size of the exchange? I checked users mailboxes sizes and they does not seems big enough to fill up the tape.

Thank you,

mailbox sizes will not reflect the actual file size, the best thing is to check the edb size or use


Get-MailboxDatabase -Status | select Name,@{Label="Free Space";Expression={$_.AvailableNewMailb
oxSpace.ToMB()}},@{Label="Size";Expression={$_.DatabaseSize.ToMB()}},@{Name="Number";Expression={(Get-Mailbox -Database
$_.name).Count}} | ft -auto

You need to locate .edb file & check the properties of your .edb to find database size of your exchange

This may be a case of database whitespace. We can check the whitespace in the DB by running the cmdlet:

Get-PublicFolderDatabase -status | ft Name,databasesize, AvailableNewMailboxSpace

I recommend you either do an offline defrag using esutil /d  

http://technet.microsoft.com/en-us/library/aa997972(v=exchg.80).aspx

Or as indicated in the following Spiceworks post, you can create a new database and move your user mailboxes to it, then delete the exisiting database.  This essentially accomplishes the same thing as an offline defrag, but without the downtime.
