Hello Guys,
in my current Szenario I have one big domain. Lets call it contoso.com. Every department has its own subdomain like department1.contoso.com, department2.contoso.com etc. Some of those departments has its own M365-Tenant. We currently do not a connection between those two worlds as every subdomain has its own tenant. The fact that every department has its own Tenant is nothing that i can change, so I need a solution that connects department1.contoso.com to department1.onmicrosoft.com (for example). Im currently searching for possible ways solving this issue. Ive already read something about Alternate Login ID. What would you gues suggest me to search for?
Thanks!
