Error message: "The document [Document name] could not be saved. The file has been changed by another application" - Problem with files on OneDrive

Problem: an alert is shown indicating that Prism cannot save documents stored in Micorsoft OneDrive

There is a known issue in which Prism cannot save documents located on Microsoft OneDrive. In these situations, the following alert is shown: "The document [Document name] could not be saved. The file has been changed by another application." This is a system alert generated by macOS, and is related to Microsoft OneDrive functionality (not an error caused by Prism).

There have been complaints reported on the microsoft.com forums that similar issues occur with files from Apple Pages, Apple Preview, Adobe Acrobat Reader, and Microsoft Office.

Solutions

• Turn off the Files On-Demand feature in OneDrive Preferences. Here is how.

• Pause syncing when editing, and resume syncing after finishing editing (then continue your work on other devices, if needed). Here is how.

• Make sure, OneDrive is updated to the latest version.
