Is it possible, to add an Microsoft 365 mailaccount, when the zammad instance is not reachable from the internet?
We have setup zammad in our active directory network, which has a .local domain. To get a ssl certificate for our zammad instance, we have set up split dns. The zammad uses a subdomain from a public domain, we own.
If i set up microsoft 365, there is the callback url with our public domain, which points internally via dns to the zammad server in the LAN. Due to this, the M365-authentication won’t work. Is there a way to add such accounts without opening the zammad server to the internet?
