Hello! We've got Exchange 2016 server and Retention Tags and Policies set on it.
One of tags is to move items to Archive after 1 year.
So, it works and all items older than 1 year are already in archive database.
The question is: they want us to change policy from 1 year to 3 years and to get items back to main mailbox.
If I just change 1 year to 3 in Retention tag, will items go back automatically or I should start EMS script?
