I have a 2012 Domain Function level and just extended the Schema with Exchange 2016 using Admin Command Prompt of Setup.exe /PrepareSchema /IAcceptExchangeServerLicenseTerms. This completed successfully. I can go into ADSIEdit and connect to the Schema and see the CN=ms-Exch-* values.
However, when I go to Attribute editor either through ADSIEdit or AD Users and Computers, none of these values show up for a user.
Why does ADSIEdit show the schema being extended, yet I can't see those attributes? I've already rebooted the domain controller.<style><br _moz_dirty="" /></style>
