I am having issues with a new Exchange 2016 deployment on server 2016
Just a little bit of backstory:
- This is a replacement of our old exchange 2010 server which is installed on SBS2008
- We created a new local domain (WIN Server 2016) to which exchange 2016 was added, so it was not a migration from 2010 to 2016
- I have exported the CA signed certificate from 2010 and imported into the exchange 2016 management console
I have set all internal DNS records on the DC. External IP has not changed. Also changed all the routing in the firewall to point to the new exchange server. Send and recieve connectors, accepted domains are all set. I have also set all the Virtual directories to poin the appropriate mail.company.com
Already tried the connectivity tester as shown in the attached files.
I can send email from and to addresses inside of the network (to both internal and external mail-addresses, I can access OWA and recieve/send mail on both andoid/ios devices. However outlook clients can only connect to exchange from inside the network, not externally. 2nd problem is that the internal outlook clients get the message: "The name of the security certificate does not match the name of the site".
I have tried removing the certificate and imported it again but i get the error message:
"A special Rpc error occurs on server *Servername*: The internal transport certificate cannot be removed because that would cause the Microsoft Exchange Transport service to stop. To replace the internal transport certificate, create a new certificate. The new certificate will automatically become the internal transport certificate. You can then remove the existing certificate."
Thanks for your help.
