Intermittent SharePoint item download failures in Veeam Data Cloud for Microsoft 365

As of March 25, we have deployed an update globally and are seeing stable operation. 

 

While no new instances of the error are being observed, we are continuing follow-up work to ensure all previously impacted scenarios are fully resolved. An update on this work will be provided as soon as possible.

As of 12:30 UTC, our engineering team has deployed a fix for the issue impacting the Microsoft SharePoint & OneDrive API. We are no longer observing new errors. However, some customer files that were backed up in recent weeks may continue to exhibit issues during restore until remediation is completed.

Our Veeam Data Cloud engineering team is now working to identify and reprocess any files that were impacted during this period.

We have identified an issue with the Microsoft Sharepoint & OneDrive API resulting in some restored files to cause errors when opened with Microsoft office. We are currently working on mitigating this issue and are doing a joint investigation with Microsoft.
