Freron MailMate

My company has a bit of a complicated setup, and just implemented multi-factor authentication with an identity provider connected to Office 365. When I try to login with my credentials, nothing happens. It doesn't seem to be rejecting my password.

I've successfully done this before, but not since we implemented MFA. There is no way through our IdP to get an application specific password. I've confirmed that IMAP is enabled on our Office365 account.

Any advice or ideas appreciated.
