OK. I was assuming the ‘rights’ were those that I have over the address book rather than those granted to others. The object being nothing if I haven’t shared it makes sense I guess.
In which case how can I test if the current user (i.e. the one Formativ is running against) has write rights over an addressbook within the addressbooks collection?
I realise I can just try and update which will then fail but I not particularly keen on that sort of approach.
