Office 365 - duo based 2-factor not working

Any updates on this ticket? I'm having the same issue.

My university just decided to only allow 2 factor authentification with Duo from now on. So as of 30 minutes ago, I cannot use MailMate anymore. Are there any plans on implementing a fix?

The test releases of MailMate do support OAuth2 which means 2FA should be supported, but I don't know if something about Duo means that this isn't sufficient. Here's the latest test release: r5810.

Note: If it works in Thunderbird then I believe it should also be possible to make it work in MailMate.

Will I get that release if I turn on "Beta Builds" in the prefs?

@David: No, currently you'll have to retrieve it manually as described here.

I'm very hesitant with regard to making an automatically downloaded beta available or a public release, because I've changed a lot in the recent year. Some users do not like when a (however small) feature breaks on an update.

Hi Benny, thanks so much for getting back to me (stupidly, I didn't check back here before as I was under the impression that I would receive an email if the ticket is updated).

Using the test release version of MailMate works great!!

Can confirm. This works for me. Thanks.
