I didn't keep mNotes long enough for it to do the damage that VZW Wireless Sync did.

As I recall, mNotes added the category and then pushed out a change to the meetings that I originated. Of course, the other parties didn't understand why they needed to receive a changed meeting notice. Just that unexpected change led me to uninstall it.

Wireless Sync did HORRIBLE things like making one hour meetings expand to over 24 hours spanning multiple days. My assistant had to cancel and reschedule a lot of meetings. I didn't disclose why my calendar was destroyed, of course.

I vowed to never use a product not supported by our IT department that also modifies Notes server data. I'd rather forward the email to a POP or IMAP user ID before doing that.
