I have an exchange server that is running out of space but it doesn't look to be related to active mailboxes. The .edb database file is 69GB but when I run the command:
Get-MailboxStatistics | Sort-Object TotalItemSize -Descending | ft DisplayName,@{label="TotalItemSize(MB)";expression={$_.TotalItemSize.Value.ToMB()}},ItemCount
I find that only 12GB of mailboxes are on this exchange server. Why is the database file far larger than what the actual user mailboxes are?
