hi Guys,
trying to integrate imp 10.5.2 with exchange 2016 for calendaring status. this IMP is already installed and working for everything else. just the calendar "in a meeting" is not showing. they also use it on adroid/iPhone so this integration required for those status.
I have few questions regarding this integration along with compatibility.
I couldn't find any document saying that 10.5. is supported with exchange 2016 or not. anyone has any idea?
also I am looking for firewall requirement as there is a firewall sitting between IMP and exchange. this doc shows (table 19).

looking at the same i am kind of confused of ports requirement for EWS - HTTP/TCP /IP SOAP ? isn't it 443 TCP?

Microsoft Exchange uses this port to send notifications (using NOTIFY message) to indicate a change to a particular subscription identifier for calendar events. Used to integrate with any Exchange server in the network configuration. Both ports are created. The kind of messages that are sent depend on the type of Calendar Presence Backend gateway(s) that are configured.
