Exchange 2016 – Check mailbox creation date

There may come a time when you have been requested to provide HR or your manager a list of mailboxes and their creation dates.

This is a simple task to do, lets jump right to it.

Firstly, launch the Exchange Management Shell (EMS) and enter in the following command:

• Get-Mailbox * | Select-Object Name,whenMailboxCreated

You will get a list of all mailboxes as we used the * option in the command, you can narrow this down to one user if you need to as follows:

You can also use the “whencreatedUTC” object, remember that whatever your timezone the time might be different, for example, if we use the command with the “whencreatedUTC” switch it shows 2 hours behind, see below active directory properties:

If you double click on the value above you will see the box below, time shown in UTC.

This should also work for Exchange 2010 and 2013.

hope it helps.
