Hi, We are experiencing a strange situation with Skype For Business. A few of our users are reporting that when they search for certain colleagues, they are found in the Skype address book but they are showing as presence unknown. When others search for the same people, their presence is reported correctly. We have tried the following for a user who is being presented with the presence unknown problem: Copying over a cached address book to the affected machine by replacing the GALContacts files in C:\users\<user>\AppData\Local\Microsoft\Office\16.0\Lync\sip_<user>; Removing all the files from the sip_<user> folder and allowing Skype to re-create them; Removing any contacts from the user's Skype favourites list for people who are being reported as presence unknown; Removing any contacts from the user's mailbox for people who are being reported as presence unknown. None of the above has solved the problem. Has anyone experienced this before, and if so, do you have any suggestions about what we can try next? I've googled the problem and haven't found anything except what we have already tried. Caroline.
