Reauthorizing with the M365 global administrator

This article walks through reauthorizing Datto SaaS Protection for M365. M365 global administrator privileges are required to reauthorize SaaS Protection's access to M365.

Environment

  • Datto SaaS Protection for M365
  • M365 Admin portal

Description

This process could adversely impact your backups if not completed properly and should only be used when directed by Datto SaaS Protection support or communicated through an official Datto SaaS Protection announcement.

IMPORTANT  To prepare for Microsoft's deprecation of the Exchange Web Services (EWS) API on October 1, 2026, SaaS Protection of Exchange services will be migrated to the Microsoft Graph API by June 30th, 2026. To continue running Exchange backups, you must reauthorize your M365 accounts by May 30, 2026.

Use either of these procedures to reauthorize Datto SaaS Protection for your M365 accounts:

  1. Navigate to the M365 reauthorization URL located here.

  2. Log in to your M365 tenant as a global administrator.

  3. In the Permissions requested dialog, grant access to SaaS Protection's Backupify application by clicking Accept.

  4. SaaS Protection is reauthorized.

Repeat this procedure as needed to reauthorize additional M365 tenants (for your other SaaS Protection M365 organizations).

When working with an organization in SaaS Protection, a banner displays if reauthorization is needed.

To reauthorize SaaS Protection's access to the M365 tenant:

  1. In the banner message, click Reauthorize Now.

  2. A separate browser tab opens where you are prompted to log in to M365. Log in to your M365 tenant as a global administrator.

  3. In the Permissions requested dialog, grant access to SaaS Protection's Backupify application by clicking Accept.

  1. SaaS Protection is reauthorized and you are returned to the organization view in SaaS Protection.

NOTE  If the banner message still displays, reload the page.
