Hi guys,
Thanks for all your replies, I have recreated our blocking policy with the folder method and still getting the same error, it has improved things as this is the only one, instead of having all sorts relating to fonts, etc. Very weird, did some internet based research and in past versions there was an update application that could be added to the allowed policy and this would solve the error, been through all the folders relating to Office and there is no sign of this app, set updates to both manual and then automatic, this has not changed anything.
