AD User deletion and mailbox deletion

Hello,

An AD user account linked to a mailbox was deleted several months back.  I was wondering where can I verify the retention period for a mailbox before it gets purged after the AD user has been deleted?

I've looked into Retention Policies but I am not sure they are being used since there are no mailboxes linked to the policies.

Thank you,

Jeannette

Check if mailbox has its own retention policy or it is using DB settings:

Get-Mailbox -Identity mailboxname | select database,UseDatabaseRetentionDefaults,RetainDeletedItemsFor

Check database retention policy and maintenance schedule:

Get-MailboxDatabase DBNAME | select name,DeletedItemRetention,MaintenanceSchedule

Use this https://technet.microsoft.com/en-us/library/jj863440(v=exchg.150).aspx if you need permanently remove the mailbox.

---- You can check this using Get-MailboxDatabase DBNameHere | Select Name, MailboxRetention 

MailboxRetention is by default 30 days if you haven't change it.

I've looked into Retention Policies but I am not sure they are being used since there are no mailboxes linked to the policies.

---- There are some of the retention policies created by default during setup (eg. Default Archive and Retention Policy) but it won't be assigned to any user by default, that you need to do manually...

Thank you,

Hi,

If you delete a mailbox, it is disconnected for a default period of 30 days, so we can reconnect it during that time. 

After the specified mailbox retention period, a disconnected archive mailbox is purged from the Exchange mailbox database.

We can use the below command to retrieve the retention policy for Morriss mailbox:

Get-Mailbox Morris | Select RetentionPolicy
