Exchange port 80 changed to 443

Question

Exchange port 80 changed to 443

We changed our web outlook from 80 to 443 no problems, web works, BB works. The BB's only had to change http to https and email flows.
None of the iPhones can connect including the person that went to store, set it up correctly but no go. Are iPhones unable to retrieve via SSL?
With SSL and the cert, the logins are pretty simple, And this

http://mail.domain.com/exchange changed to
https://mail.domain.com/exchange
The login example is:
domain\name or name
password

It should work but it does not, Suggestions>?

Yes, it works. Preferred actually...

Make sure the "Use SSL" switch is turned on in the Exchange account on the iPhone. SSL runs on port 443 and ensures the phone connects to the https address.

If it already turned on or doesn't fix it, I would delete the account on the phone, then add it back.

Still nada.
"The mailbox server [domain.server.local] has its [exchange] virtual directory set to require SSL. Exchange ActiveSync cannot access the server if SSL is set to be required."

Well it's supposed to but not.

Check this KB from Microsoft.

I had to do this on our Exchange server to get ActiveSync to work with SSL enabled. Do you have a Front End server?

We have an only Exchange server and yes I saw that kb article but thanks anyway. Since we use SSL only, the devices and web outlook work fine on 443, I am not doing server changes for a single user much less a group. BTW, the iPhone didn't connect to SSL on register.com either.
The solution for now is to send their email to a pop3 outside and they can connect to that unsecured.

Thanks everyone for the help.

Wait - the phone can't connect to OWA using Safari over SSL? If that's the case then this sounds like a possible certificate issue. The device will certainly use SSL; however, are you using a certificate provided by an intermediate CA from GoDaddy or one of the other vendors? If so you need to ensure the intermediate CA's certificate is installed on the phone so we can verify the entire chain of trust.
