Microsoft 365 Is Not a Full Backup

Many organisations assume that Microsoft 365 automatically provides a permanent backup of their emails, OneDrive files, and SharePoint data. Unfortunately, this is not the case.
Microsoft 365 includes limited retention and recycle bins, but these are not designed as a backup solution. In most cases, deleted or overwritten data can only be recovered for around 30 days.

What's at risk?
-
Exchange Online (Emails & Mailboxes)
-
OneDrive files
-
SharePoint sites and documents
Once Microsoft’s recovery window has passed, the data is permanently lost.
Common causes of data loss
-
Accidental deletion or overwrite
-
Ransomware attacks
-
Compromised user accounts
-
Leaver accounts being removed
-
Malicious or unauthorised deletions
Microsoft’s platform is built for availability — not long term recovery, ransomware rollback, or historical restores.
