IM and Presence Service Web Page Does Not Open from the Microsoft Lync Client Default Web Browser.
Problem When the Microsoft Lync client user accesses the IM and Presence Service menu item, the default web browser cannot connect to the IM and Presence Service node and the IM and Presence Service web page does not open.
Solution When the Microsoft Lync client user accesses the IM and Presence Service menu item, IM and Presence Service should open a web page in the user's default web browser. If the web browser cannot connect to the IM and Presence Service node, check the following:
-
Ensure that JavaScript is enabled in the browser settings.
-
Enter the following address in a web browser to verify that the browser can connect to the IM and Presence Service node: https://imp_server_address:8443/cucmuser/showHomeMini.do?mini=true
Where imp_server_address is the hostname, FQDN, or IP address of the IM and Presence Service node.
-
If you specified an invalid IP address or FQDN for your IM and Presence Service node, repeat the plug-in installation procedure, specifying the correct IM and Presence Service node address.
-
If you experience other connection problems, you may need to do the following: -
Add the web address of the IM and Presence Service node to the list of trusted web addresses in the browser on the Microsoft Lync client computer. In Microsoft Explorer, select Internet and add the following entry to the list of trusted web addresses:
https://<IM and Presence_server_name>
-
Add the HTTPS web address of your domain to the security zone of the IM and Presence Service node. In Microsoft Explorer, select and add the following entry to the list of web addresses for the security zone: https://*.<your_domain>

If an error message appears informing the users that they do not have permission to use this feature, you must enable the users for Microsoft Lync in the IM and Presence Service node. See Remote Call Control Setup.

If an error message appears regarding an un-trusted security certificate issue or similar warning, select Continue. Most browsers allow you to download a website security certificate and mark it as trusted.
