iPhone cannot verify server identity, exchange active sync

Recently a user was getting this error on their iPhone:
Cannot verify server identity

Long story short its due to server certificates and various IOS's.  The users impacted had IOS 7, but it looks like an on and off issue since IOS 4.
The solution I found was to manually install the server certificate on the phone.

Get a copy of the CA certificate, either by emailing it to yourself or the user, or having it loaded on an FTP or something like that.

Tap the certificate and tap install.  Enter your passcode and you're done.

There is a great walk through for adding the certificates with screen shots here:
