Investigating - Microsoft Outage

Microsoft is experiencing an outage affecting its services, which began earlier today (Thursday Nov 12, 10 am PST onwards). The outage is not yet resolved. It is affecting access to Microsoft 365 services like Exchange Online, OneDrive, SharePoint, Teams, and as a result, some Microsoft 365 backup jobs managed by Cohesity may have failed, been delayed, or not completed as scheduled.


What this means for you
Backup jobs that ran during the outage window may show as failed or incomplete.
Your previously completed backups and recovery points are not affected.

What you need to do
No action is required. Once Microsoft restores service, Cohesity will automatically resume your backups, and any missed data will be captured in the next successful backup run. You do not need to re-run jobs or change any configuration.

What we’re doing
Our engineering team is monitoring Microsoft’s service health and will confirm that backups resume normally after service is restored. We will update this notice when the issue is resolved.

You can follow Microsoft’s progress on the Microsoft Service Health dashboard. Once Microsoft confirms the issue is resolved, rerun any failed jobs. Most will complete successfully on the next scheduled run or when retried manually. Please allow some time for backups to catch up. If failures continue after Microsoft’s recovery notice, please contact Cohesity Support.

Thanks,
Cohesity Team.
