Exchange 2013 ActiveSync Not Working
I have an Exchange 2013 server running in my environment. I have recently had to change the IP address of the server. I have changed the host (a) records and updated pointer records. _autodiscover also points to the dns host record and not the IP address. Everything seems to be operating correctly except ActiveSync. I did an nslookup on my server and it comes back to the right address. I have run the Remote Connectivity Analyzer on ActiveSync and it comes back with the following errors.
Attempting to test potential Autodiscover URL https://domain.com:443/Autodiscover/Autodiscover.xml
Testing of this potential Autodiscover URL failed.
Attempting to test potential Autodiscover URL https://autodiscover.mail.com:443/Autodiscover/Autodiscover.xml
Testing of this potential Autodiscover URL failed.
Attempting to contact the Autodiscover service using the HTTP redirect method.
The attempt to contact Autodiscover using the HTTP Redirect method failed.
Attempting to contact the Autodiscover service using the DNS SRV redirect method.
The Microsoft Connectivity Analyzer failed to contact the Autodiscover service using the DNS SRV redirect method.
Everything in DNS seems to be correct. What am I missing?
Thanks.

So change my SRV record to an IP address or what do you mean?

The _autodiscover SRV record is:
Domain: domain.com
Service: _autodiscover
Protocol: _tcp
Priority: 0
Weight: 0
Port Number: 443
Host offering this service: exchangeserver.domain.com
Domain: domain.com
Service: _autodiscover
Protocol: _tcp
Priority: 0
Weight: 0
Port Number: 443
Host offering this service: exchangeserver.domain.com

I changed the "Host offering this service" to the IP address and it still comes back with the same errors. Could it be something in IIS?
That is in your EXTERNAL DNS?
As the error being reported means the testing service cannot see your DNS record.
Have you checked with one of the numerous external DNS testing services to see if the Autodiscover SRV record is seen?

While looking at my external DNS I had forgotten to change port 443 to map to the new IP address of the Exchange server.

Your SRV records cannot be correct.
Although that shouldn't stop ActiveSync from working, because ActiveSync rarely uses Autodiscover (most ActiveSync devices don't support it correctly). Therefore you should do the test that allows you to manually enter the server address, rather than using Autodiscover.
