Update 08/06/2015 : I found another technet page explaining that the same federation route need to be set for every pool in the organization -> https://technet.microsoft.com/en-us/library/JJ204800(v=OCS.15).aspx

It is also explaining that even you set up only one federation route A/V traffic will go through each respective Edge pool, only SIP, IM will go through the Edge pool set for the federation route.

Hi,

Some weeks ago, we found that our OWA(O365)-Lync(On-Prem) integration was not working completely.

Here is the status :

  • Presence -> OK
  • IM with someone in the same Lync pool -> OK
  • IM with someone in another Lync pool -> NOK

I was getting this error message :

IM OWA Error message Federation

After troubleshooting with MS, we found that the issue was the fact that we had for each front-end pool a different federation route. Each front-end pool was using it’s own Edge pool for federation and that caused the issue.

This is also wrote in the followed technet page : https://technet.microsoft.com/en-us/library/jj688121(v=ocs.15).aspx
