What we would like to do is this:
Company A has an existing AD domain with a 365 tenant with email and SharePoint.
Company B has an existing AD domain with a 365 tenant with email and SharePoint.
We would like to move email from the Company B tenant into Company A tenant, and leave the SharePoint alone for now. The basic question is whether we can sync 2 AD domains into 1 Tenant using AAD Connect? I believe we can from what I have read.
Does anyone have experience with this scenario? Does this seem reasonable? Ideas on how to proceed?
