Our customer has Office 365 tenant and have a requirement to populate GAL with contacts from legacy email system (Postfix) as well as from two other companies who has separate o365 tenants. As far as I undestand, neither dirsync nor galsync is an option in multi-tenant scenario.
What is preferred way to fetch user accounts information from Azure AD? I'm getting completed-no-objects when running an Import with AAD Connector.
I'm going to make provisioning either via powershell or WAAD Connector. Do I miss something in this setup, or it will work just fine?
