There are no retention policies applied to any folders in your UAlbany Mail mailbox. Mail that is delivered to your Inbox or Junk folder will remain there until you move or delete the item. Similarly, sent mail will remain in your Sent Items folder until you move or delete the item. Deleted items will also remain in your Deleted Items folder indefinitely unless you hard-delete an item or empty the folder. Mail may still be recovered for up to 14 days after it leaves the Deleted Items folder.
Note that every mailbox has a 50GB size limit. New mail cannot be received after the quota has been reached.
