[MlMt] Exchange Error - "server does not support any authentication methods"

[H. Jonah Lefkoff]

Hi Mailmate Gurus,

I’m running r6272 with three accounts, one of which is a @hotmail.com 
outlook account. I’m unable to send messages from this account, but 
can fetch and move existing messages between folders/trash just fine. 
Watching the activity viewer under the SMTP tab for this account while I 
press the “retry” button on the failed send, I get the following 
log:

```

```

Is there some setting I need to change to allow me to send outgoing 
mail?

Thank you!

Sincerely,
Jonah
