Q: We have a gap between patches and are concerned about breaking some appointments to fix others. Is there any negative impact to running the Exchange-side Time Zone Update Tool with the recurringonly switch?
A: Recurring meetings are handled well, time zone information is already contained in them.  If you use the RECURRINGONLY switch you will not be updating any of the single-instance appointments.
