What I am looking for is some information on whether there is an Outlook setting which would force Outlook to hide accept/decline options for specific settings in my iCalendar text. I'm pretty sure the client have been facing these issues and they are not just complaining. I have verified the invitations on my computer and others computers too, on Outlook 2003, 20 and all of them seem to display thei nvite to me just fine, that is, with the normal options. I have been googling a lot on that but could not even find a hint which could point me towards a solution. The problem I'm facing is that some times clients complaint that they don't get options to accept/decline/tentative an invitation. I have been working on iCalendar for quite some time now and after a long and hard effort I have an iCalendar format which is acceptable to more or less all versions of Outlook.
