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

    Come on Microsoft - how many people have to report this as an issue (almost open a year now). Can you please fix your **** software or stop charging us for it until it actually works !!!!

    How hard is it to have an email app that reliably sends emails !!!

    You can also write the draft in the outlook app, then open the Mobile outlook app, find the draft and send it.. that works too. Just very annoying
