I have a scenario where the company needs to keep the appearance of an internal resource but have Exchange send it out to an external resource.
Here is the scenario. The company has multiple accepted email domains on Exchange 2013. One of them we will call @internal.com. I need to have Exchange change any emails that are sent to @internal.com to be sent instead to external.com.
So for example , Jon Doe sends an email to Jane@internal.com , I need Exchange to accept this but then deliver the email to Jane@external.com
I checked transport rules but do not see a way of doing this.
Any help would greatly be appreciated.
