Email Protocols - what can I turn off?

[Adam in DC]

Looking for best practices to reduce footprint around email protocols as they relate to meeting rooms and RealConnect and Trios and Group Series.

• It appears that EWS is required.
• I assume MAPI is required.  
• Can POP and IMAP be turned off?
• What about SMTP?

Thanks.

Adam, I'm not quite sure what the scope of this question is but in terms of a Trio connecting to a mailbox in Exchange Server or Exchange Online or the OTD service connecting on behalf of a device like a Group Series or Studio X series device the only protocol used is HTTPS via Exchange Web Services (EWS).  The devices do not use SMTP, POP, IMAP, etc.

Thanks Jeff.  My motivation was around security hygiene - what can I turn off that I don't need.  That's exactly what you answered.

I had a second thought.  Though the Poly device may not require MAPI - I assume MAPI will still be necessary in order to see a calendar in Outlook for desktop.  If you turn off MAPI - then you'll only be able to manage the calendar via the web.  That may not be suitable for many orgs.
