MIM 2016 GAL Sync - Contacts not created

Hi.

I'm working with MIM 2016 in a lab environment. 

I'm probably missing a step, but I can't seem to get MIM 2016 to create contacts in the OUs of each domain. I have two untrusted domains, contoso and wingtoys. I setup MIM in contoso and created a managment agent for both domains. I ran full import and sync, and I ran export.

When I check Metaverse Search in MIM, I see all the email accounts from both domains, but these are not showing up in AD as contacts, or in the Exhange Address book. What do I need to do to get these into AD?
