OAuth for Sub-Domains RRS feed

  • Question

  • Hello All,

    I am running an Exchange 2016 on-prem environment with multiple domains and have an Office 365 tenant. I have setup OAuth connectivity between my Exchange and Office 365 environments already to allow access to services like Calendar application in Microsoft Teams.

    These services are currently working fine with my primary domain, however it's not working with my subdomains. I have tried to add the sub-domains to exchange on-prem using the New-AuthServer commands with new names but it still says the value is the duplicate of the existing entries for the primary tenant. Any advice?

    Will be grateful for your kind assistance
