This is a very basic question on Office 365 Exchange online MRM policy for Deleted items. The default MRM policy indicates for Deleted Items the Retention action is Delete and Allow Recovery with retention period of 30 days. Does this mean
1. The mail items in Deleted items folder will be deleted automatically after 30 days and will allow for recovery
OR
2. Does it mean when a mail item is deleted from the deleted items folder it is recoverable for 30 days

The first.
The second is controlled via Set-Mailbox -RetainDeletedItemsFor
The default value for Office 365 Exchange Online is 14 days with a maximum up to 30 days.

SolutionJust to add that the Default MRM Policy in ExO should *not* have the Deleted Items tag in it, they removed this one few years ago. If you want to ensure that items in the Deleted Items folder are automatically removed after some time, you need to rename the default policy or create a new one with that tag and assign it to users.
