Thanks for your help so far, much apreciated!
Is it just a Web Client issue - or a server issue ?
If you have enabled external users to invite the room (I believe you said you have this configured) and you login to a gmail account for example, open the Calendar app, create a new event, and invite firstname.lastname@example.org and email@example.com to the meeting - then you should get a response back from the server to say whether the boardroom has accepted/declined the invite.
If that part works - then perhaps it is just a client issue.
