Changes to Microsoft Authentication for Exchange Online C2C Backups

MS OAuth Change

 

Microsoft will be deprecating Basic Authentication for Exchange Online prior to completely removing the authentication method on October 13, 2020. Basic Authentication passes username and password with every request, which is not as secure as Modern Authentication based on OAuth 2.0. This is a token-based authorization process that eliminates the use of usernames and passwords.

As a result, in order to comply with Microsoft policy for secure authorization, you will need to re-authorize your Safe Data Storage Exchange Online backups using OAuth. 

To switch to OAuth, you will need to login to your Safe Data Storage account and do the following:

  1. Log in to your account.
  2. Click on the Office 365 Exchange backup task.
  3. Click the "Connected" or "Disconnected" icon.
  4. Click "Use OAuth based authorization".
  5. Click the "Authenticate" button.
  6. Login to your Microsoft backup services account to complete the authentication.

These changes must be made prior to October 13, 2020 to ensure your Exchange Online backups continue to run each day. Any Exchange backup still using basic authentication after October 13, 2020 will no longer work. You can find out more on the changes to authentication in this Microsoft Developers Blog.

Although Microsoft will still support credential based authentication for SharePoint, OneDrive, Groups and Teams, we recommend that you also change these backups to OAuth at this time. This will provide greater security for your data and will eliminate any issues in the future when Microsoft eventually deprecates credential authentication for these services.

Please contact support@safedatastorage.co.uk if you have any questions or need assistance changing your backups to OAuth based authorization.
