Message Offline files – Working offline keeps “popping up” on laptop

Hi,

This problem started on 1 computer and now there are 2 more with the same. They do not loose contact with the network because outlook and other apps are running fine. Only seems to be “offline files related”. Have e.g. tried to map drive using IP address instead but no success. Anyone have had this problem? Grateful for more tips on how to troubleshoot this further. Thanks in advance!

Regards, JC
