Hi

Check the SRV record sipfederationtls._tcp.domain.com with port 5061 pointed to.

Also please make sure the port 5061 traffic isn't blocked by any firewall on both sides. Check if you have any Event errors.

Hi Raju,

Thanks for the quick reply... I issue is particular to IMexpert. Which is unable to find company2 users presence.

Whereas, normal users are able to find the presence after engaging with and conversation.

Yes check the above it might be the Federation configuration issue.

you are using Lync for IM Right?

Did you checked the configuration. Can you check the Connectivity using test connectivity.
