I use to have my web application on the server root, where the web application was accessible from the following URL :-
And the Lync ActiveX was working well . Then the client asked us to change the URL to have the following format
“www.companyname.intra” instead of
http://servername. So I added the required mapping inside the SharePoint alternative access mapping configuration, and the intranet became available from the new URL
But I have noticed that the Lync ActiveX have stopped working after renaming the web application URL , while if I access the web application from the old URL the activeX will work well and it shows the user statuses. so can anyone advice what might be the problem ?
