Hi All,
Until now, I did believe, that some properties from synchronized Objects from On-Prem to Entra ID like Emailaddresses and HideFromAddressLists can only be changed on the Source in Active Directory.
I discovered that you could change the HideFromAddressLists property for synced MailUsers in Exchange Online EAC and EXO Powershell.
User Mailbox If you look at a syncronized User Mailbox in Exchange Admin Center the “Hide from global address list (GAL)” is greyed out and can not be changed.
