Way of New Outlook for Mac connects to Office365 and way old Outlook on Mac connects to Office365

Occasional Contributor

Hi All,

Was curious to understand the working of New Outlook on Mac, right from establishing a connection with office365 to mail-flow. Every mechanism NewOutlook uses when compared to Old Outlook, I tried searching everywhere, but couldn't find anything.

 

ForEx: what protocol and port is sed by New Outlook on Mac, and what protocol and port used by old Outlook.
