Issue Status: ONGOING

Issue Description: Users may be unable to open some files in the Microsoft Project Online desktop client from SharePoint Online.

More info: This issue specifically affects opening Microsoft Project Plan (MPP) files. Affected users can bypass the impact by starting the Microsoft Project Online desktop client before attempting to open MPP files. Once Microsoft Project Online has been started, affected users can open MPP files without issue. If impact reoccurs, users can start Microsoft Project Online on their desktop again to bypass the reoccurring impact. Additionally, users may be able to open these files through Project for the web as an alternative while we troubleshoot this problem.

Current Update: 14/06/2024 09:03:00 AM – Microsoft have completed their investigation and discovered that the root cause is associated with a user interface (UI) modification included in a previous Microsoft Office update. They’re developing a fix to remediate the file access issues, which will be deployed in a future Office release. They’ll monitor the status of the fix and share more information at their next scheduled update.

Scope of impact: Any user attempting to open some files in the Microsoft Project Professional desktop client from SharePoint Online may be impacted.
