How to edit Exchange Online attributes for a tenant with AD-Sync with ease
Hi, when you synchronise your on-premises AD to Azure AD with AADC, it is Microsoft recommended/supported practice to install an Exchange 2016 management server and configure hybrid co-existence. If you have O365 Enterprise licensing, then you will qualify for a free Exchange 2016 hybrid licence key. This is conditional on no mailboxes being present on the server. This is the best way to manage attributes such as secondary email addresses in a hybrid identities methodology.
However, it is also possible (but not really recommended) to manage on-premises attributes without the Exchange Management server by using either ADSI edit (to be used with great caution), or by enabling Advanced Features in AD Users and computers, which will enable the attribute editor tab in the user properties. These methods will allow you to add and remove smtp addresses by modifying the proxy addresses filter setting.
I highly recommend the first option, as it is free to setup if you have O365 E1 or E3 licences and offers far more control of those attributes which must be managed on-prremises. You just need to spin up a server to install Exchange 2016 on (which may require a schema update), and then you can run the Hybrid Configuration Wizard.

Just to add to the above, at minimum you should extend the on-premises AD schema with the Exchange attributes. Regardless on whether you plan to keep an Exchange box for management purposes or not.
