Try adding -Verbose to the end of the line. What it looks like to me is that some required attribute is missing other than the one you're trying to set. Also, run Get-OwaVirtualDirector | fl and post the results here.Ed Crowley MVP "There are seldom good technological solutions to behavioral problems."

Hi, Try to restart exchange server to reconnect DC then try to configure the external URL through EMC. What's result?
