Hi Tom, I had this problem, and I'll describe why I had it in case it's the same reason.

  • Linux: "3-bar" menu button (or Edit menu) > Preferences
  • Any system: type or paste about:preferences into the address bar and press Enter/Return to load it

In the left column, click Privacy and Security

Depending on how you access Microsoft365, you might need either or both of these:

Make sure to include the https:// at the beginning, and don't use any wildcards that you may see in old instructions.
