This is a tough one to Google as I'm not sure how to word it. I have 2 (actually 3) domains that my company owns. One named after the business, and one that has nothing to do with the business. When one signs into Outlook through the program or OWA with the business domain, everything works as expected - GAL, business contacts, etc.
I created an email address with the other domain. When I sign in to Outlook with the secondary address (have only used OWA so far) I still see the GAL, suggested contacts, distribution lists, etc, from the business address.
I would like to have these 2 email addresses completely ignorant of each other and unassociated in any way.
The main goal that I am trying to achieve is to create an email distribution list that only the new email address can use or access, and I don't want the new email to be able to...
