Exchange Online doesn't have any provision to restore items such as calendar entries, contacts, journals, notes, posts, and tasks to a previous version.
Also, when any item, including email, is deleted, the item is moved to the Deleted Items folder. Even if the contents of the deleted items folder is emptied, you can still recover the item if you restore it within 30 days, beyond which the items cannot be recovered, except for calendar entries can be retained for a maximum of 120 days.
This post will explain how you can use RecoveryManager Plus to restore an Exchange Online mailbox item to a previous version or recover an item that has been deleted for more than 30 days.
