ARCHIVED: If the Microsoft Lync federation between Indiana University and another organization isn't working
The Microsoft Lync servers at Indiana University use certificates issued by InCommon. Therefore, for the federation between IU and another organization to work, the Lync administrator at the federated organization will need to confirm that the InCommon Server CA issued by AddTrust External CA Root is in the Intermediate Certification Authorities store on the organization's Lync Edge server(s).
Also, if the other organization's administrators have not enabled automatic partner discovery on the Lync Edge service, they will need to allow the following IU SIP domains for federation:
indiana.edu iu.edu iue.edu iuk.edu iun.edu iupuc.edu iupui.edu ius.edu iusb.edu
All SIP domains share the following Edge servers:
bl-edge-access.ads.iu.edu in-edge-access.ads.iu.edu
