Hi, 

I'm looking for the best pratice on how to add alias, before joining to hybrid I could add alias for single or shared account in O365 but after hybrid join I can't see a way to add for shared account in O365.If now I would like to add alias for user account I have to go to local AD>User>user attribute>Proxy address> smtp:alias@keyman .comMy enviroment: One AD forest with One Domain (local)1 O365 Tenant with 25 domains

There isn't on-premise Exchange server. Does anyone have any suggestions on how to add an alias to shared account in o365 if we have Hybrid join.? 

Many thanks
