Excel fails to open files when offline

[geekmedic]

To all:
When any of or computers (laptops, desktops, tablets) are offline excel will not open any files. ( it starts fine but fails to open excel files (CSV, XLSX, XLS, etc). It gives the attached error.
Our computers are attached to a domain. When using a local computer user account this error does not occur.

This happens regardless if the file that it is trying to open is stored locally on the C Drive, on a USB stick, etc.

Any Ideas?
