3. Trusted Documents – tick the ‘allow documents on the network to be trusted’ if not already ticked.
4. Trusted locations – add the C Drive (or whatever drive your docs are in) if not already in list, and tick ‘allow trusted locations on my network’. May have to restart your PC.
Do the same for Excel if you want Excel previews in File explorer.
