The Evolution Exchange connector uses the Exchange Open Web Access (OWA)
interface, which is essentially the Exchange webmail interface, to
contact Exchange.  Thus, to use the connector you need to have the Web
ports open (80 and 443, for HTTP and HTTPS respectively).

However, the new mapi-provider backend talks to the server using
Microsoft MAPI protocol, which is the same protocol that Outlook uses to
talk to Exchange.  This protocol uses different ports, of course, since
it's a different protocol.
