Hello

I have Exchange 2016 and I have ADFS and MS Teams.

I have configured HMA and working perfectly with Exchange 2016 , Also out calender synced with MS Teams.

I have no mailboxes hosted on Office 365 and all mailboxes on-Prmise

Do i still need to allow the below ports:

https://learn.microsoft.com/en-us/microsoft-365/enterprise/urls-and-ip-address-ranges?view=o365-worldwide

I already ran the Exchange hybrid Wizard and the HMA working fine but do i need to leave all the Endpoint between My Exchange onprimse and Exchange online allowed.

what is the required ports in my case should be allowed ?

Is it mandatory to Exchange hybrid configuration to do HMA?
