As a user of Office 365 Business or Enterprise services, you may be wondering if all of your work data and outlook 365 is backed up and how to restore outlook365 emails when needed.

Your email accounts are replicated several times in different datacenters to avoid any disaster or loss of data. The databases that host your accounts are also protected from software or hardware corruption by using mechanisms offered natively by Microsoft Exchange. There is also the possibility of recovering items deleted by users for a period ranging from 14 days up to several years if necessary. Indeed, it is possible, depending on your Office 365 subscription, to create retention strategies that will allow you to recover the items deleted by your users even after several years.
