I am a programmer and don't have experience in Outlook configurations. Our company has two email domains namely xyz.com and xyz.biz. Each employee has an email id on one of these domains but not both depending on the project they are working on.
The problem we are facing is that when a communication email is sent from the Accounts, HR, Admin, etc departments, they need to send the email twice. Once through the xyz.com account to all employees with an email address on xyz.com and once through xyz.biz to all employees with an email address on xyz.biz. I am not sure why they have to send two separate emails but the IT team has directed all departments to do so as there is no other solution according to them. Even though two different groups have been created, sending an email to employees in a group of xyz.biz from xyz.com does not seem to work.
I want to know if Outlook provides a feature such that we can configure some kind of rules to send an email through an id on xyz.com to all users on xyz.com and the same email gets sent automatically to users on xyz.biz through an id on xyz.biz.
The only technical details I know is that we are using Exchange 2003 and the IT team claims that this is a limitation causing the problem.
Edit 1 :
Our company is split into two main divisions depending on the type of projects. I am pretty sure I use domain XYZ wheras the employees in the other division use the doman ABC to log in into the windows machine or outlook itself.
Also, employees in domain XYZ can access the machines on the network in domain ABC but not the other way around
Edit 2: There is one correction. The employees can access only those machines in the network which are in the same domain as theirs. Cross domain access is not possible over the network. On the other hand, employees are able to send emails to anyone regardless of which domain in which the recipient or the sender is. The problem occurs only when a communication email is sent out that uses email groups instead of email-id's.
