I'm looking for the best practicee on how to add alias, before joining to hybrid I could add alias for single or shared account in O365/Exchange online but after hybrid join, I cannot see a way to add alias for shared account in O365. Each time I add alias for shared account in O365/Exchange I gets a error says "We couldn't save your changes. Please try again. "If I would like to add alias for user account, I cannot do it via the O365/Exchange online, I have to go to local AD>User>user attribute>Proxy address> smtp:alias@domain.com that's how I can get alias for user accounts
My environment: 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
