List mailboxes based on creation date

Just a quick one liner to list mailboxes based on the date when they where created. In the example below I list all mailboxes created the last week:

Get-Mailbox -resultsize unlimited | where {$_.WhenMailboxCreated -gt (get-date).adddays(-7)} |ft Name,whenMailboxCreated -Autosize

If you want to change the number of days just edit –7 to the number of days matching your preferences.

That’s all, take care and have fun!
