Have some users that have Office 365 E3 licenses with huge mailboxes. Already have the archive set up for these users and have been moving items manually. Want to automate the process to have all emails (anything in any folder including sent and deleted items) go into the Office 365 In-Place archive that are over a year old.
What's the easiest way to handle that through the Office 365 Portal? I already set up a Retention Tag called '1 Year Move to Archive' type default, 365 day retention period, and archive as the retention action.
Do I need to set up a new Retention Policy with that Retention Tag and then apply it to the user? Will that do everything in their mailbox including all email folders, sent, and deleted items?
