I have limited access to our hosted exchange server, and whenever I need to add internal/external contacts I would have to go through a panel that the service provider created.
After adding an external contact through the panel, I would go to my outlook > address book > GAL ,and I can see the contact added.
But when I send a message to an external contact, the email address is replaced with an alpha numeric placeholder with my company's domain instead of the actual external contact's email address. (i.e. firstname.lastname@example.org)
I know this is something for the service provider to work on, but is there a way to upload contacts to the GAL on my end so I can make the external contacts available to all employees in our company?
