Folder-by-folder incremental backup of every mailbox to portable
.eml files, including hidden folders.
Delta-synced file backup with full version history and original folder structure preserved.

Every calendar and contact folder snapshotted on each run, versioned by change key.
Microsoft 365 group conversations and in-place archive mailboxes, selectable company-wide.
Every notebook page exported as HTML, organized by notebook and section.
Automatic SHA-256 verification after every job, plus on-demand re-verification of the whole archive.
Date-filtered ZIP exports with JSON manifests, and configurable age- and version-based retention.
No agents, no consultants — just your browser and an Azure app registration.
Register your organization with an email and password. The first account becomes the owner; invite admins and viewers any time.
Follow the guided in-app steps to create a read-only Entra app registration. Your client secret is encrypted at rest and validated with a test connection.
Pick what to back up for each user, select company-level sites, teams, and mailboxes, then set an hourly-to-weekly schedule. Backup365 does the rest.
Backup365 treats your tenant data the way regulated teams need it treated — least privilege in, verified integrity out.
Backup365 requests only the application permissions it needs:
Every plan starts with a 15-day free trial and includes verification, exports, retention, and the audit log.
Create your account and you get full access to everything for 15 days — no credit card required. When the trial ends you can still sign in, and all of your backups and settings are preserved, but backups pause until you subscribe. Subscribe any time to pick up right where you left off.
Microsoft keeps your services running, but its shared-responsibility model makes your data your responsibility. Retention windows are short, and deleted or corrupted content can be gone for good. Backup365 keeps independent, verified copies you control.
Per user: Outlook mail, OneDrive, calendars, contacts, and Teams chats. Per company: SharePoint sites, Teams channel messages, Microsoft 365 group mailboxes, in-place archive mailboxes, and OneNote notebooks. You choose what to enable, per user and per item.
Mail, OneDrive, and SharePoint use Microsoft Graph delta queries, so after the first run only changes are transferred. Snapshot sources skip any item whose version has already been stored.
No. It requests read-only application permissions and never writes back to Microsoft 365.
Create a date-filtered ZIP export for any user or company item. Mail
exports as standard .eml, files in their native formats,
OneNote as HTML — plus a JSON manifest with hashes for every item.
Yes — Microsoft gates Teams message export APIs behind an additional protected-API approval for your app registration. All other sources work with standard admin-consented permissions.
Try everything free for 15 days — no credit card required. Set up your company, connect your tenant, and run your first backup in under fifteen minutes.
