messages sent from outlook email do not arrive at destination inboxes on Firefox, but they do when logged in to outlook on Edge. What is happening in Firefox that the sent messages don't get delivered?

Is there any error message when you click Send or afterwards?

Is this the only problem you've noticed using Outlook in Firefox or are there other symptoms which might provide more clues?
