Hello experts. I am new to this subject and need your help, I have no experience with this particular issue.
The system administrator before me set up a domain server and exchange in the company, let's say it is mycompany.local. We also have a domain with email accounts at GoDaddy, mycompany.com, and you can email to them using me@mycompany.com. In order for users to get their external email in Outlook, they each have a POP3 account which points to the mycompany.com mail servers. If they want to send email externally through Outlook, they must select the POP3 account they want to send from and use that to send their message. If they want their message sent internally, they select the Exchange email account. Each user also has different POP3 accounts with other GoDaddy hosted domains (e.g. mycompany2.com) that they would like to be able to send from.
I know that Exchange is smart enough to handle this a better way. Basically what I would want to accomplish (in a perfect world) is that the user can go into Outlook, receive all their email from their GoDaddy accounts, reply to them, send email externally and internally, all with only having 1 exchange account set up in Outlook.
I know I will have to set up some MX records and such on the domains at GoDaddy, but I am just lost on what I should do there and what I need to do in Exchange to make this happen. Help! I am using Exchange 2007.
