Recently our central IT worked with Microsoft to convert our departmental mailbox to a shared mailbox, which broke outbound email for us in Zammad. I’ve asked that they convert it back to a usermailbox to restore oubound mail in our Zammad instance. It was unable to authenticate for outbound but inbound was fine. Any chance to make outbound mail work with a O365 shared mailbox in future releases?
As far as I understand this problem, it’s a problem on microsoft side, as I don’t understand the technical difference in terms of authentication. I’ve worked for years with exchange and don’t seem to get it.
Maybe this is only a office 365 issue, but currently I don’t have time for a test setup in that direction.
sending and receiving via shared mailboxes is already possible, but you have to have a valid user with an O365 license. This user needs to have a “send as” premission setup. You just have to set the sending address to the shared mailbox address and that’s it (authenticate as this user in your outbound settings).
Can someone show a screenshot example of how to do this? Having issues authenticating. I have checked that my account has send as access on this mailbox in office365.
