Hey everyone! I'm reaching out for some help with our Office 365 setup. We have an on-premises Active Directory (AD) forest with a structure that includes a parent domain and five child domains, each representing different companies. Each child domain has its own Domain Controllers (PDC and ADC). Currently, we have Exchange 2019 set up in the parent domain and we're using Azure AD Connect to sync all users to Microsoft 365. The issue is that our users are being created with two accounts: one in the child domain for logging into their workstations and another in the parent domain solely for email access. We want to streamline this so that users can use the same AD account from their child domain to log in to their workstations and access their Exchange Mailbox. Any suggestions on how we can achieve this?

Have you set up a two-way sync between the parent and child domains? That should allow you to link the accounts effectively, enabling users to log in with their child domain accounts and access their mailboxes without the duplication issue.
Thanks for the reply! Are you referring to AD Connect Sync for that?
