Question : How do I get exchange emails to come from a different address?

The email is [email protected]. The username on the domain and exchange login is [email protected].  On his IPhone and IPad in order to get email i must enter the [email protected] and all emails leaving those devices come from [email protected] instead of [email protected]. I need for those devices to send email out as [email protected].  Or any other fix for this would be great.

Answer : How do I get exchange emails to come from a different address?

go to the user properties on Exchange management console (if exchange 2010 or 2007), or in active directory users and computers (if exchange 2003) and change the primary smtp address, also know as send as address.
