I understand that the retention period for a user's Deleted Items is set at the database level using the -RetainDeletedItemsFor object. For example, this value for Database1 is set at 60.00:00:00.
If I create a retention policy and retention tag that should remove Deleted Items after 45 days then assign that policy to an individual user (the mailbox exists in Database1), which takes precedence?
Here's my testing parameters: After assigning the 45 day policy to the a test user I issue this command:
Start-ManagedFolderAssistant -Identity TestUser@mycompany.com
I then perform a Get-Mailbox command to verify that the 45 day retention policy has been assigned to the TestUser's mailbox (it has). Yet the number of messages in the TestUser's Deleted Items folder does not change (a couple of hundred messages have dates greater than 45 days ago and should have been removed).
What am I missing?
