We were going to buy a bunch of licenses for work to eventually replace OUtlook but we can’t get passed the Office/Microsoft 365 login loop and failed authentication errors. I guess we’ll be staying on Outlook until we can find yet another mail client that actually works.
This is still a problem. If you cannot change things server side - and with universities or companies you cannot - this problem is unsolvable without support from Mailspring. I have not been able to find any at all. For me, that means that Mailspring is of no use to me. Pity.

It’s July 2024 and this is still an issue for O365 mail, even with the authenticated SMTP selected (which is not ideal). Shame as getting this working was the last thing preventing me from going for the paid version. Hopefully this will finally be resolved.
Any way to fix this issue by changing the code and building the app on windows? How to fix this without using the SMTP authentication?
If your M365/Office365 tenant (Education/Corporate) doesn’t have IMAP and SMTP enabled, there’s not much you can do. This client doesn’t support native Exchange, EWS, or ActiveSync sadly…
