Our company here in KSA is using like 10 e-mail accounts hosted at a mail hosting company ( @companyksa.com ), when I came here I installed Exchange 2003, my plan was to host our e-mail accounts on our server, but then our mother company in Spain required that all employees from all branches should only use the company's e-mail domain ( @company.com ), so they required us to create a connector on our exchange server so that all the users here will get e-mail accounts at the company's domain name, they sent me the plan, I created the connector and used the configurations they told me to use, and they created a connector on their server, but the thing is that I can send emails from my new e-mail account ( @company.com ), but I cant receive any email here! And to make it worse, we cant now receive e-mails from any user in @company.com domain on our e-mail accounts that are hosted at the mail hosting company!
Our exchange here is working only internally now, we are using @companyksa.local to send messages within our internal network.
