Unable to open documents on campus-hosted SharePoint sites with Office online apps

Description

Update – April 7, 2025 3:00pm – Resolved

Documents hosted on campus-hosted SharePoint domains should open in Office online applications now. There was a configuration issue with the application service.

SharePoint sites on campus-hosted domains may return an error when opening documents via web-enabled Office online applications.  As a workaround, documents can be downloaded and opened with desktop versions of Office apps.

SharePoint sites with sharepoint.com addresses are not affected.

SharePoint admins are currently working to resolve the issue.
