Microsoft’s service agreement is clear about the shared responsibility model: Microsoft keeps the service running; customers are responsible for their data. Native recycle bins and retention help with recent, accidental deletions — but they have time limits, they can be emptied, and they were never designed as a backup system.
For an accounting firm, the exposure is concrete: a mailbox purged after an employee departs, a SharePoint library overwritten by a sync error, files encrypted by ransomware that faithfully syncs to OneDrive, or a malicious deletion by a compromised account. When native retention windows pass, that data is gone — unless an independent copy exists.
MangoCloud maintains automated, independent backups of your Microsoft 365 tenant: Exchange Online mailboxes (including calendars and contacts), OneDrive for Business, SharePoint Online, and Teams-related data where supported by backup platforms. Copies are stored outside your tenant, encrypted, and retained on schedules you control.
Recovery is granular and managed: a single email, a folder, a document version, a full mailbox or an entire site — restored to the original location or an alternate one. Every backup job is monitored, and reporting shows your protection status at a glance.
Multiple daily backup points across covered workloads, running without anyone remembering to click anything.
Keep restorable history for the periods your firm's practices require — well beyond native limits.
Restore items users deleted and only missed after recycle-bin windows closed.
Recover from insider actions or compromised accounts that purged data intentionally.
Recover one email, one file version or one folder without rolling back everything else.
Bring back entire mailboxes or SharePoint sites after major incidents or offboarding mistakes.
Preserve leavers' mail and files affordably without paying for their license forever.
Jobs are watched daily; you receive clear protection-status reporting.
Enforced for all remote access to hosted servers.
Data encrypted in transit between users and the environment, with encrypted backups at rest.
Managed EDR watches hosted systems for suspicious behavior.
Backup copies are separated from production infrastructure to limit blast radius.
Backup data is encrypted in transit and at rest.
Copies are stored independently of your Microsoft 365 tenant and its credentials.
Restores are performed by authorized personnel under MFA, on documented request.
New users and sites are added to protection automatically or flagged for inclusion.
Microsoft's responsibility: keeping Exchange, OneDrive and SharePoint online. Excellent — and unrelated to whether your deleted data can be recovered.
Recycle bins and retention policies help with recent mistakes, within time limits and subject to configuration. They are safety nets, not a backup system, and they live inside the same tenant they protect.
Separate, encrypted, monitored copies with long-term retention and managed restore. This is the layer that answers for your data when the first two can't.

We don’t just fix tech we bring clarity, confidence, and continuity to your business operations.
365 backup integrates with our server backup and DR services — one provider answers for all your data.
You ask for data back; we do the restore work. No portal spelunking during a stressful moment.
We're clear about what backup platforms can and can't capture (for example, some Teams data types), so expectations match reality.
Server failure, ransomware, fire, regional outage — disasters differ, but the question is the same: how fast can the firm work again? DRaaS gives you a measured, rehearsed answer.
Tax and accounting firms hold exactly the data attackers want. Security as a Service puts managed detection, identity protection and continuous monitoring around it — without you hiring a security team.
Client records are the product of your firm’s work. We protect them with encrypted, immutable backups, offsite copies and recovery procedures we actually exercise.
Help desk, administration, patching, monitoring and honest guidance — delivered by a team that supports accounting firms all day, every day.
Microsoft provides availability and limited native retention, and its shared responsibility model places data protection with the customer. Native tools have time limits and live inside the tenant. Independent backup exists to cover what they don't.
Typically multiple times per day per workload, giving you several daily recovery points for email and files.
Yes, if the mailbox was under protection — this is one of the most common restores we perform, and retained backups can also replace paying for a leaver's license indefinitely.
Teams files (which live in SharePoint/OneDrive) are covered; chat and channel data are protected where Microsoft's APIs and the backup platform support it. We document exactly what your plan captures.
No. Backup runs via secure API connections in the background. There are no agents on devices and no impact on how anyone uses Microsoft 365.
