I have K-9 email on my Android phone, and it can send email to outlook just fine. But mutt on my Ubunto 17.?? system cannot send email; it always gets "SASL authentication failed".
Here is what K-9 has for its outgoing server: SMTP server smtp.office365.com Security STARTTLS Port 587 Require sign-in Authentication Normal password (as opposed to encrypted oasswird or certificate) Here is what I have for mutt: smtp_pass xxx (just the password; I have also tried user@company#pass and several variations) smtp_url smtp://user:pass@comp...@smtp.offic365.com:587/ (I have also tried outlook.office365) ssl_starttls yes (I have also tried ssl_forcetls) There is no sendmail on this system (yet). It bugs me that the damned phone can send directly via office365.com, but not this "real" computer. And here is mutt -v: NeoMutt 20170113 (1.7.2) Copyright (C) 1996-2016 Michael R. Elkins and others.
