Rescheduling Outlook Calendar Meetings creates duplicate meetings

Scenario:

1.       Meeting request comes in.

2.       User accepts.

3.        Meeting shows as accepted in calendar.

4.        An update comes in.

5.       User accepts.

6.        Now there are TWO meetings: The new one and the old one.

I found a workaround, but I believe that MS will release fix for this issue.

Go to TOOLS > OPTIONS > PREFERENCES > EMAIL OPTIONS > TRACKING OPTIONS and turn OFF PROCESS RECEIPTS AND REQUESTS ON ARRIVAL.
