Client is using Mac Outlook 2011 with Exchange 2010
When a new Calendar item is created with a recurring item (every 2 weeks) with a specific end date, the user gets the "Data is Corrupt" error 19943.
As a temporary workaround I have them creating a specific # of recurring instead and that does seem to be working.
The item was had a location set, the time zone included, and was categorized.
I was able to finally narrow it down to something to do with setting the appoint as recurring with an end date. The first occurance was 3/6/12 at 8:00am.. the final was set to 5/29/12 (default that popped up when I select by).
Redoing the appointment in the same way but setting the recurring to after xx number of meetings allowed me to successfully create a meeting.
Thanks
Dan
