Retain Unified Archiving 4.x
When running Mailbox Deletion, the logs show the following line:

What does this mean?
Customers will only pay for a Retain license for each user that has archived data stored in Retain.
A check was added when running Mailbox Deletion to ensure that any empty mailboxes are not active and will not be using a license.
