Update - Investigation status:

We continue to actively work on a fix for this issue and are targeting the release of a hotfix early next week. This remains subject to development progressing as planned and the hotfix successfully completing our testing and validation processes.

Nov 13, 2026 - 10:33 UTC
Identified - Investigation status:

We continue to work on this issue as a priority.

A fix has been identified and is being progressed through our development and testing processes. This will result in a hotfix being issued as soon as we confirm that the changes successfully mitigate the issue and our testing protocols have been satisfied. We will update on an ETA for the hotfix as soon as one becomes available.

We can confirm that the issue is limited to customers who have One Drive sync client enabled.

Investigating - Impact: degraded functionality
AutoSave is intermittently disabled when opening Office documents using Cloud Drive Mapper for a subset of customers.
When this happens, changes will not save automatically. Document co-authoring is also affected.

Investigation status:
We are investigating this issue as a priority.
Our findings so far suggest a recent Microsoft OneDrive version update is impacting our file-handling and co-authoring processes. We are working to conclusively establish root cause and determine a suitable resolution.
We can confirm that the issue is limited to customers who have One Drive sync client enabled.

Recommendations:
- Before editing, check whether AutoSave is enabled. If AutoSave is off, save your work manually and confirm that changes have saved successfully before closing the document. Unsaved changes could otherwise be lost.
- Reverting to an earlier OneDrive version also provides a workaround. We are providing further guidance directly to impacted customers as to how to make this change.
- Disabling the One Drive sync client will also alleviate the issue.

Resolved - Service has now been restored sufficiently for us to resolve this incident whilst Microsoft continue to complete global recovery. Iris MFA tokens are being received more slowly than usual but the system is accessible. We are receiving mail-based tickets into Support. CDM error rates have dropped by 80% compared to this morning.

We recommend that customers who require continued updates on the Microsoft recovery rollout follow progress at https://status.cloud.microsoft/

Update - Latest recovery update from Microsoft:

"We're seeing continued recovery progress across affected regions, with broader improvements now observed in North America and sustained improvements across much of Europe. We're also seeing encouraging recovery signals in Asia Pacific, although some users may continue to experience intermittent access issues or delayed email delivery as mitigation progresses across the remaining affected infrastructure.

Our focus remains on stabilizing recovered infrastructure, completing mitigation in the remaining impacted areas, and reducing delayed email queues and backlogs. We're closely monitoring service consistency and validating recovery across different connection methods as we work toward full mitigation."

We are beginning to see improvements in terms of mail congestion and general service performance which is having an associated improvement in IAM Cloud services.

Nov 13, 13:50 UTC
Update - Latest recovery update from Microsoft:

"We've made additional progress toward service recovery, with recovery actions completed across portions of the affected infrastructure in the Asia Pacific region. Traffic is being gradually restored, and we're seeing improvements in key customer scenarios, including mailbox access and delayed email processing. However, some users may continue to experience intermittent issues.

Our focus is now on extending these recovery actions across affected infrastructure in other regions, while continuing stabilization efforts and adding supporting capacity to improve service consistency.

Reducing email queues and backlogs remains a priority, and the extended 48-hour email timeout window remains in place to help protect delayed messages as delivery catches up."

Nov 13, 11:16 UTC
Monitoring - Latest from Microsoft:

"Recovery actions are ongoing and have progressed in phases across affected Microsoft 365 infrastructure. Global telemetry and customer reports show incremental improvement in several workloads; however, service health remains variable and capacity has not yet fully returned to baseline.

Network and traffic-management actions remain active. To protect email during recovery, we’re continuing to prioritize queue and backlog processing, and the email timeout window has been extended to 48 hours to preserve delayed messages."

Investigating - Microsoft are experiencing a prolonged global service outage which is affecting Microsoft and Microsoft-reliant services such as CDM

Impact statement:

- Drive mapping via Cloud Drive Mapper may be impacted
- Access to Iris is impacted due to inability to receive MFA OTPs to complete authentication flows
- Users may not be able to complete CDM trials registrations
- Customers may not be able to raise Support tickets and are recommended to use our support Portal. Users who have not registered to use the portal may not be able to do so.

Fix
Microsoft is responsible for fixing the issue. We understand that a network-level change has been implemented to prevent further server crashes but global recovery is likely to take several hours.

We will continue to monitor status.
