I have googled like mad on the issue and can not fix the following:
I changed the SSL on the exchange from domain.local to domain.com, i had to apply the certificate via IIS to the exchange service and can confirm that all external Web access and SSL is working as expected. I have changed the local exchange URL to match the external URL and have confirmed via EMS, my internal client machines are failing on the Exchange Server name now when connecting.
The SAN certificate has the following 5:
when the client outlook connected to the exchange the server settings are still ServerName.Domain.Local and not ServerName.Domain.Com and as such they are failing on the final check each time.
Am i missing a step here to point the client to the correct new server name?
