[MlMt] Forcing OAuth2 reauthorisation

Hello,

I use mailmate to with 3 email addresses. For one I rely on oauth2 to 
connect to a Microsoft outlook SMTP server. As of the last few days when 
I try to send a message I just see the message go to Drafts and have 
state "Pending submission".

I wonder if the OAuth authentication may have expired. If so I would 
have thought that Mailmate would automatically trigger OAuth dance, but 
this doesn't seem to happen.

* Is there a way to force the OAuth dance?

Or is a different diagnosis likely, perhaps mailmate no longer being an 
authorised app on the server end?

I see no sign of activity in the SMTP tab of the activity viewer when I 
send a message. There are 4 lines showing EHLO messages but no obvious 
error state:

```
ˇSMTP -- xyz at smtp.office365.com
   EHLO [IP 1]
   EHLO [IP 2]
   EHLO [IP 3]
   EHLO [IP 4]
```


Many thanks for any input,

Greg Jefferis.
