Issue with iPhone and ActiveSync of Exchange 2010 ...

Hello to all, a customer has a Windows Server 2008 R2 Service Pack 2 and Exchange 2010 SP3. Exchange 2010 comes from a migration to Exchange 2003 installed on Windows Server 2003 SP2, now I have a problem with connecting an iPhone to Exchange 2010 where Exchange ActiveSync does not have SSL: the message that returns iPhone after the stage of creation of the account "exchange" is: Title "Exchange" - Message "Unable to verify account information." I tried to remove the SSL protection, but nothing to do. I have found in the event viewer error "1053" of "MSExchange ActiveSync." I do not know where to turn, everything seemed so easy to achieve.

Thank you and good job

Paolo

Exchange 2010 has SSL encryption by default. Make sure that "Use SSL" is "on" on your iPhone.

SSL is not optional with Exchange 2010.
A self signed certificate is not supported for use with ActiveSync either.

If you haven't already, you need to get a commercial SSL certificate - suitable types are available from around US$60/year. Then configure Exchange to use it everywhere.
