Inbox Retention policies

Question

Hi, We need a retention policy that deletes all items older than 90 days from the Inbox folder in primary mailbox but doesn't delete items from the Inbox in the Online Archive.  Is this configuration possible? How?

Hi,@Piphil

Thanks for posting your question in the Microsoft Q&A forum.

Unfortunately, such configuration is not possible, as tags assigned to a given folder in the main mailbox will apply to the same folder in the Online Archive. Read for example here:https://learn.microsoft.com/en-us/exchange/security-and-compliance/messaging-records-management/retention-tags-and-policies#applying-a-retention-tag-to-a-folder-in-the-archive

From a retention perspective, the primary mailbox and online archive should not be looked at as separate entities. Retention settings are applied to the primary mailbox, and by design, extend to the online archive. The online archive is an extension of the primary mailbox.
