Since Comcast forced migration to office 365, I am able to receive emails with Thunderbird but I'm not able to send. The outgoing server is set to smtp.office365.com per Comcast instructions. This is a business account. However, this will not work with TB and I am wondering if there is a fix for this issue? I am able to send from the office 365/Comcast website, but I would like to continue to use TB.

I use these settings: 

     INCOMING: account46, , (imap) imap-mail.outlook.com:993, SSL, passwordCleartext
     OUTGOING: , smtp-mail.outlook.com:587, alwaysSTARTTLS, passwordCleartext, true

And yes, it is an Office 365 account.

Thanks for the suggestion, Zenos. Seems to be working now. I can say that the Cloud Solutions team at Comcast was not very helpful.
