What you’re seeing
- The only protection for email and OneDrive is the recycle bin and Microsoft's built-in retention.
- A deleted mailbox, SharePoint site or departed user's OneDrive turned out to be unrecoverable past a certain date.
- No one can say how far back a file or message could be restored if it were deleted today.
- Licenses for former employees were removed, and their data disappeared along with them.
Common causes
Every environment is different, but these are the causes our engineers find most often:
- Microsoft's shared responsibility model keeps the service running but leaves protection of your data against deletion, ransomware and misconfiguration to you.
- Deleted items, version history and recycle bins only hold data for a limited time before it is purged permanently.
- Removing a user's license or deleting their account starts a countdown after which their mailbox and OneDrive are gone.
- Ransomware on a synced PC can encrypt files that OneDrive then faithfully replicates to the cloud.
- Retention policies were never configured, or were built for compliance holds rather than for day-to-day recovery.
Why it matters
Many businesses assume Microsoft backs up everything, then find out after an accidental deletion, a malicious insider or a ransomware attack that the data is gone or only partly recoverable. Email, contracts, client files and project records now live mostly in Microsoft 365, so a gap here can mean losing years of history. Legal holds, eDiscovery requests and industry rules may also require you to produce records long after the built-in retention windows have closed. An independent backup gives you a recovery path outside the account that was compromised or deleted.

Frequently asked questions
Doesn't Microsoft already back up our data?
Microsoft protects against its own hardware failures and keeps the service available, but its recovery options for user mistakes and attacks are time-limited. Once those windows pass, deleted data is generally not recoverable by you or by Microsoft support.
Can data deleted in the past still be recovered?
Only if it is still within Microsoft's retention periods. An engineer can check what is still recoverable and protect it before it expires.
Does a third-party backup need access to all our email?
A backup service needs read access to the data it protects, granted through an approved application in your tenant. We explain exactly what permissions are involved before anything is set up.
