Exchange 2010 Retention Stamping

 

 

 

Managed Folder Assistant processing: Retention Hold and Migrated Mailboxes

While engaged at a customer for Exchange 2003 to Exchange 2010 migration project, there were various requirements around retention/aging.  Migrating from Exchange 2003 aging to Exchange 2010 Retention strategy was quite a hurdle for the client.  Reason being there were various capabilities in Exchange 2003 (such as email notification of expired items) and other legal speed bumps that warranted a deep dive into retention policies (RPs), retention policy tags (RPTs), Managed Folder work cycles, and how the Managed Folder Assistant processes mail items.  The table below provides a list of various mailbox setting profiles and what the resulting affect is following the manage folder assistant runs against the mailbox.

Mailbox migrated

· RetentionPolicy applied
· RetentionHoldEnabled = FALSE
