Hi everyone - has anyone had issues with sending emails using Outlook 365 for Macs? Especially a red error box that appears at the bottom (attached) and says "Message failed to send Open" The email is then stuck in drafts with the option to continue editing but it is simply frozen in drafts and the only way is to delete and try again. Alternatively, you can go to the webmail version of outlook, find the drafts folder and send from there. This has been happening on/off for several weeks now, no pattern, just happens occasionally.

This version of Outlook 365 is absolutely **** with so many issues

    Ok, so the problem has started again for me on a couple of email replies. Tried the "Schedule Send" and added a couple of minutes. Seems to work every time with that approach. Happy to have a work around but...... Come on Microsoft!!! This can't be a huge issue to fix!

    I just tried this "workaround" of adding 15 seconds before the email gets sent out and it's still not working. Geez.... we're talking about sending email. It's 2024! Is it that hard to get "sending email" correctly?

    What now?
