Hi @garethirwin1234,

 

Thanks for flagging this and sorry to hear it's impacting multiple people across your org.

Could you please confirm if the affected users are on Windows and whether they recently installed the Microsoft update KB5074109? Also, are any macOS users seeing the same behavior, or is this limited to Windows only?

It would also help to know where the files are being saved when the warning appears. Are they saved locally on the machine, or in a synced location like OneDrive or Dropbox, or on a network or external drive?

Please also take a look at this thread and let me know if the issue you're seeing matches what's described there:

If it's the same behavior, a bug is already logged, and I've shared the latest update and next steps in my pinned response on that thread. If what you're seeing is different, let me know, and we can troubleshoot this further with you.

 

Looking forward to your update.

Abhishek
