[MlMt] Office365 not working anymore

[Raza Rizvi]

Hi Angelo,

Might this be because the server admins have configured only a subset of 
mail clients to connect - for example Outlook?

I can’t use MailMate with my corporate Outlook365 service because it 
throws up a HTTP based authentication/ask the admin for permission box 
and the admin won’t let me connect using MailMate.
