Running a powershell command to display users mailbox size, item count etc....and along with that the last logon and logoff time. Problem is the last logon and logoff times all say 2:00 AM or somewhere around there. After giving it a brief moment of thought, it's getting that from System Maintenance (Mailbox Assistant) which runs every night starting at 2:00 AM. How do I get the clients (the actual user) last logon for mailbox. We have some mailboxes which I know are not being used but according to my spreadsheet, I can't tell because the Mailbox Assistant is time stamping everying when it runs maintenance. Do I actually have to disable maintenance for a few days just to get a valid timestamp?
