We have installed office 365 on a new pc but macro enabled workbooks have been disenabled and the button above doesn't allow us to enable macros on this pc. We don't have this issue on any other pc. We have tried uninstalling and reinstalling office 365, also we have wiped the hard drive by doing a factory reset but nothing has resolved the problem and 'technical support' (case number: 1018125555) have not been able to assist. We understand this is a known issue? Glad of help please?
