One of the most common misconceptions we hear is that Microsoft backs up your Microsoft 365 data. Microsoft protects the platform; you are responsible for your data. Deleted mailboxes, ransomware-encrypted SharePoint libraries and malicious insider actions can all result in permanent loss without a third-party backup.
What Microsoft actually provides
Retention windows, recycle bins and version history — all of which have time limits and can be bypassed by an attacker with admin rights.
What a proper backup adds
Independent, immutable copies with unlimited retention, granular restore of a single email or an entire site, and protection that does not depend on the tenant remaining healthy.
Our recommendation
Every Olatech managed plan includes Microsoft 365 backup for Exchange, SharePoint, OneDrive and Teams, tested quarterly. If your provider does not, ask why.
