Webmail: The connection was reset. iPhone: Unable to verify account information

Our webmail webpage has stopped working.
Users of Firefox receive "The connection was reset" error.
Users of IE receive "Internet Explorer cannot display the webpage" error.

Users trying to update their mailboxes on iPhone's "The connection to the server failed"
or when trying to add an exchange account to an iPhone, we see "Unable to verify account information."

I have reset IIS, I have reset the Exchange Information store (I have not restarted the server)
Port 443 is open.

In-fact when attempting to access the exchange server's web pages via it's local IP, name or FQDN I see errors in IE and Firefox.

The server is 2003 R2

You need to check SSL and activesync is all set up correctly.

If you have 3rd party SSL certificate make sure it is not expired, same with self-signed i guess.

I always use this guide to ensure that virtual server properties are set correctly:

That's a great guide, unfortunately I have already followed it.

Our SSL certificate is valid until mid 2014.

Hi, having read the guide again I missed the final steps.
I've ran a test using testexchangeconnectivity.com.

Here are our results...
Testing the SSL certificate to make sure it's valid.
The SSL certificate failed one or more certificate validation checks.
Test Steps
ExRCA is attempting to obtain the SSL certificate from remote server mail.???.com on port 443.
ExRCA wasn't able to obtain the remote SSL certificate.

Additional Details
The certificate couldn't be validated because SSL negotiation wasn't successful. This could have occurred as a result of a network error or because of a problem with the certificate installation.

Has Powershell sent you back into the Stone Age?

If managing Active Directory using Windows Powershell® is making you feel like you stepped back in time, you are not alone.  For nearly 20 years, AD admins around the world have used one tool for day-to-day AD management: Hyena. Discover why.

I removed the Virtual Directories.
Restarted the server (so they were re-created)

Followed you link's article to ensure the correct permissions were setup.
Webmail works, iPhones still didn't.

Followed the guide again and after running the https://testexchangeconnectivity.com  test I saw 403 errors.
Followed the instructions for 403 errors and wollah. All working.

Thanks bud, that article is pretty comprehensive!
