Installed Ubuntu MATE 16.04 and configured evolution (v3.18.5.2) to talk to my Office365 mail/calendar account.
The issue is with sending an email. I press the send button after composing (or replying) and the email is queued to the Outbox, but it never leaves, even after multiple checks for new mail I have to manually do a Send/Receive to flush the email out to the Office365 server.
Let me clarify further: I am using Evolution-EWS (Exchange Web Services), not IMAP or POP. I have tried to determine what is happening by running evolution from the command line: EWS_DEBUG=2 evolution. However, I don't see any logging after hitting the SEND button in the compose window. Nothing occurs (unless I receive email) until I press the RECEIVE/SEND ALL button.
I have the following packages installed -
pmahan@Chaos-~ 7> sudo apt list | grep evolution | grep installed

I'm frankly stumped at what to look at.
