Hi,
My customer wants to merge bikes.com" into cars.com's existing hybrid-configured and federated tenant by adding bikes.com email domain to the existing tenant and create a unified GAL as cars.com users need to lookup bikes.com user in the GAL and vice versa.
Q1: Will the configuration be sufficient to provide a unified GAL in both Exchange Orgs?
Q2: If Yes, how will the users from each forest appear in the GAL in the other forest? Contacts? Users?
Q3: What would be the easiest way to enable free/busy calendar sharing between cars.com and bikes.com users? Exchange Availability service?
Thanks in advance,
Douglas

@Vasil Michev, thanks for your reply.
Could you please clarify "move users to a single tenant"?
The suggested solution is a single O365 tenant with two domains (cars.com and bikes.com) as bikes.com will keep its domain. Cars.com is already configured as an Exchange hybrid and now they want to merge bikes.com into the already existing tenant.
To get a unified GAL, will an AADConnect write-back sync suffice or does bikes.com also need to be an Exchange hybrid?
Thanks, Douglas

OK, but both domains (forests) will join the same tenant ("cars.com" already is with a majority of their mailboxes in EOL) and optionally "bikes.com" will be configured as a hybrid. Without a 3rd party tool, will on-prem users from each forest not be able to see users from the other forest in GAL?
