Current data retention policy of Microsoft for Office 365 does not offer any special protection against intentional data removal and considered it in the same way as any other deleted data. So, if the deleted emails are not recovered within the designated time frame, organizations will lose the data for good and may face drastic consequences.

3. Accidental Data Loss: Apart from these two types of threats, emails exchanged via Office 365 can get lost in some other ways. Accidental data deletion is another major reason that hampers the security of Office 365. While the bulk amount of unnecessary emails have been deleted, it is possible that the users may end up deleting some important email messages too by mistake. If this deletion is noticed within the time period of data retention, then the emails can be retrieved from the Deleted Items folder. Otherwise, the deleted data will get lost forever.
