msExchHideFromAddressLists don’t sync to Exchange Online

You run into an issue when you want to remove a synced recipient from the GAL even if you set msExchHideFromAddressLists on $true


The trick is, AD attribute “MailNickname” need to have a value. You can fill in the alias of the recipient and sync it again to Exchange Online. The check mark “Hide from address list” should be checked for the recipient in Exchange Online after the sync.
