Presence information does not show on a SharePoint page
Assume that you have Skype for Business running on the computer. When you open a SharePoint page, your presence information is not shown.
Use one of the following two workarounds, and then open the page again:
- Disable Protected Mode for Internet Explorer by clearing the Enable Protected Mode check box on the Security tab in the Internet Options dialog box.
- Run Internet Explorer as an administrator.
Why this issue occurs
The Office add-on for Internet Explorer loops though all the processes on the computer to look for the Skype for Business process so that it can use a handle to the process to communicate with it. When Internet Explorer runs in Protected Mode, Windows security restricts the process list that is sent back to the Office add-on, and the Skype for Business handle is inaccessible.
