I am trying to configure the Presence Gateway for an integration with Office 365 and failing miserably at the Presence Gateway FQDN.
All it says in the guide is that the Presence Gateway field should have either the fully qualified domain name or IP address of the Presence Gateway server. This value must match the server address that is displayed in the Subject Common Name (CN) or Subject Alternate Name field of the server certificate.
With Office 365 integration, there is no server certificate, only the root and intermediate certificates, so where do you find the FQDN to use here? I have tried using one of the IP addresses that outlook.office365.com resolve to and that allows the Presence Gateway to connect but we need to use a FQDN to ensure always on access.
I have searched through all the forums and this piece just isnt mentioned anywhere and at the moment TAC are equally confused as i am. I would expect this to be a simple setting but for the life of me, i dont know where to get it.
Thanks
Doug
