I have one question, I have local domain and custom domain. when I setup azure adconnect and office 365. I synced with the OU filtering that has user has .local and .com in the same OU. my .com domain is synced corretly but .local domain is synced to .onmicrosoft.com
My question, can I prevent .local sync to office 365 because I have thousand users have used .local, I cannot change all user to .com domain. I don't want .onmicrosoft to show in portal. and I need azure ad connect should synced automatcally when I will change UPN suffix from .local to .com. I know the attribute filtering but I don't know which attribute should i select.
