I am trying to create a way for external mail to be sent to an address in our company that would be distributed among several internal user mailboxes using a Contact in Exchange 365. Situation: there is a Contact email@example.com who is also a user in AD. I just want this contact to point to a list of other domain users so that all mail sent to it from outside of the company goes to them. Right now the Contact just points to itself and all internal mail gets bounced back to sender - #550 5.1.1 RESOLVER.ADR.RecipNotFound; not found ##., mail sent from external sources just disappears. I'm missing something basic here just not sure what it is.
Is a DL a better choice for this? Do I need to delete the contact and AD user and just create a new distribution group?
