1.1. Vendor 1 notes/results

Overall there was good interoperability. In general the vendors were able to interoperate. They were able to invite, reply, reschedule, and cancel to single instance meetings. There was some problems with the timezones that were used in recurrence rules, as a result only minimal testing was done with events with multiple occurrences. Finally, even though Microsoft was not there, some interoperability was done with Outlook.
