HCW Federation failed with Error RRS feed

  • Question

  • We are planning to configure Exchange Hybrid Configuration with Exchange 2010 SP3 server. We have AD domain 'domain1.com' and SMTP domains '@domain1.com, @domain2.com, @domain3.com" on Exchange 2010 server ( single server using mimecast as email gateway).

    We ran AAD connect for "Domain2.com" to migrate users with "@domain2.com" email addresses.

    When we ran HCW from windows 2012 r2 server ( could not run HCW on Exchange 2010 server), the federation part failed with the below error message:

    PowerShell failed to invoke 'New-FederationTrust': Unable to access the Federation Metadata document from the federation partner. Detailed information: "The underlying connection was closed: Could not establish trust relationship for the SSL/TLS secure channel."

    we have SSL certificate for "webmail.domain1.com" and Autodiscover service internaluri is https://webmail.domain1.com.

    Any help to resolve this issue is much appreciated.
