IAM Cloud incident
AutoSave issues when opening Office files through Cloud Drive Mapper
Ongoing since 04:13 PM UTC, affecting Cloud Drive Mapper.
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.
