I'm having a strange issue where suddenly SharePoint 2013 presence indicators started showing up blank:
The indicator image isn't broken, because I can browse to it. I'm not even sure what this color means. In the past it would either be red or green depending on the users Lync status. All users are affected by this.
Lync 2013 still functions fine, and presence indicators in Outlook web access are still working as well. I searched for docs on how to setup Presence in SharePoint 2013, but everything seems to point to "it just works" as long as the imported profiles contain a SIP address(which they do).
We're currently running IE11, and all intranet pages are part of the Local intranet zone. As far as I can tell, the presence indicator IS working, but it is displaying this blank status for some reason.
