Understanding retention for Exchange

Hello, I have a problem with understanding two things about retention policy for Exchange: 1. Retention period vs. deleted items retention https://docs.microsoft.com/en-us/microsoft-365/complian...

Thanks a lot. Point 1 is now clear to me.

Ad 2 but MRM policy “5 year delete” (set in EAC) will not affect disposal of deleted Teams chat messages?

If it's a default tag, it will likely apply to Teams chat messages too. They are stored in a separate folder, part of the non-IPM subtree now, but default tags apply therein as well, I believe.

    Thank you Vasil.
    It’s my last question, I promise 🙂

    If “Permanently delete” MRM tag is set up at EAC it shouldn’t prevent the user-deleted Teams messages from being disposed (permanently deleted), right? As there is no retention aspect of the policy but “delete-only”?

     

    This is how I also understood your previous post in another discussion:

    It's another name clash, but in all fairness the old ones (configurable via the EAC) did not "retain" anything. On the contrary, they were only used to delete/archive items, which is kinda the opposite of retention. The new ones, configurable via the SCC, act across the service and do actual retention.

     

    So since there is no “retention” aspect of this policy, it shouldn’t suspend permanent deletion of Teams messages from the SubstrateHolds folder?

      Yes, the "old style" Exchange retention tags do not have the "retention" aspect, they will not prevent permanent deletion.
