3.4.3. Vendor2
Vendor2 does not have full featured workflow support in yet. They do not support delegation, counter proposals or anything associated with them. While they do support the basic accept, decline and tentative acceptances, the other iTIP messages are ignored or not supported so trying them against an invitation from VENDOR2 results in an undetermined state or loss of workflow (at least from the non-VENDOR2 POV). We did not receive any Vendor2 originating workflow, they simply responded to the ones we sent out. As such, we do not know how well we interoperate with them when they are the Organizer of an event or repeating event. I was not able to find out if this was because we did not have enough testing time or if they are unable to originate iCalendar workflow just yet
