"Could not load contacts at this time."
I am getting "Could not load contacts at this time." error message while adding SharePoint messenger webpart on my page.
Going through ULS logs I found below error message recorded:
"Group cannot be found. Request (GET:http://TestMach:4141/_vti_bin/SharepointMessenger.WebServices/SharepointMessenger.svc/Contacts)"
Can you please help me to get this working as this is of high priority.
