We are using Exchange 2010 (soon to migrate to 2016).
I recently setup a retention policy to automatically delete email in the 'Deleted Items' which have been there longer than a year.
This has been applied to a number of test users and I would now like to roll it out to all users.
Is there a way to automatically apply this retention policy to any new mailboxes that we create? Or is it a case of having to manually add them?
