[COMPLETED] [Acronis Cyber Cloud] Microsoft 365 service degradation

News Update:

        Some of our customers experienced degradation with Cloud-to-Cloud backups for Microsoft 365 during Microsoft’s last maintenance release. We’ve been actively monitoring this issue with Microsoft 365 backups (https://kb.acronis.com/content/71047) and are please to announce the issue have been addressed and corrected. Our internal reporting also shows that almost all backups from the past 72 hours have completed successfully. No action is required from your side.

Acronis continues to work with Microsoft on root cause analysis.

If you still experience Microsoft 365 backup failures, please contact Exabytes Acronis Support at backup-support@exabytes.com. Please let us know the Microsoft tenant name and relevant Acronis Cloud login.
Please be informed that since Microsoft started maintenance for Microsoft 365 on August 17th, some of your cloud-to-cloud backups for Microsoft 365 may experience degradation. This affects all solutions which backup or extract data from Microsoft 365.

You may receive one of the following messages:

  •  [Microsoft][ews-code=ErrorInternalServerError]: An internal server error occurred. The operation failed”
  •  Cannot get the user’s email address for connecting to the Microsoft 365 group mailbox. At least one group owner is required to back up or recover the group mailbox. An owner must be a licensed user”.

Additionally, some users may appear greyed out in the console, although they still exist on Microsoft 365 side.

Backups are expected to resume when the ongoing Microsoft maintenance is complete. You can check the current service health status on Microsoft's website.
