Hi,
When I create a new mailbox using exchange 2016 service; MapiOverHttp is not enabled. Outlook 2016clients cannot connect to mailbox profile when this option is not enabled, while other clients can connect using RpcOverHttp.
It might be a good to have option to enable this selection / option during mailbox plan creation.
PS: To workaround; we still can use powershell to enable MapiOverHttp for a specific mailbox.
Thanks,
Levent
