Hi All
I am using exchange hybrid environment, currently we are using exchange 2010 and exchange 2016, we are yet to decommission exchange 2010. In Exchange 2010 admin console we can the tab of alias. and alias take the primary SMTP email address. I am trying to change the primary SMTP address in exchange 2016 for a user but i am not able to change it since it is taking the alias which is set in exchange 2010, how do i change the alias from exchange 2016 without making change in exchange 2010.
