--- Comment #6 from Brandon Foster <foster2cbran...@gmail.com> --- Thomas and Jan, I managed to get past the initial Folder not found error by unchecking the "Save sent mail" option in the SMTP tab of settings. But now I am running into issues authenticating to send mail. I have this sort of output in the console: SMTP >>> STARTTLS SMTP <<< 220 2.0.0 SMTP server ready SMTP ** startClientEncruption SMTP >>> "EHLO localhost " SMTP <<< 250-DM2PR11CA0014.outlook.office365.com Hello [204.78.58.42] SMTP <<< 250-SIZE 157286400 SMTP <<< 250-PIPELINING SMTP <<< 250-DSN SMTP <<< 250-ENHANCEDSTATUSCODES SMTP <<< 250-AUTH LOGIN SMTP <<< 250-8BITMIME SMTP <<< 250-BINARYMIME SMTP <<< 250 CHUNKING SMTP >>> AUTH PLAIN SMTP <<< 504 5.7.4 Unrecognized authentication type Depending on how I set the settings, I get different output - but this one looked most promising. I tried without authentication, with authentication but no encryption, as well as every other permutation of encryption with authentication. No luck yet. Any ideas? I tried changing SMTP to use IMAP SENDMAIL extension - but when I even try to compose a message I get an error pop-up that says "Set appropriate settings for outgoing messages" - the console is silent on this however. At first I thought this was because of the sent folder name again - I made a child folder under my main inbox and named it SENT and accordingly named the sent folder in settings, that didn't fix it - neither did changing it to INBOX/Sent. I wonder what's up with this one. :-/ -- You are receiving this mail because: You are watching all bug changes.
