Looking for the best practice 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 can't 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 tolocal AD>User>user attribute>Proxy address> smtp:email address removed for privacy reasonsthat's how I can get alias for user accounts
I can create new users or shared account and add alias to them but can't do with already existed shared account.
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.?
