Her most common issue was the event being scheduled on the wrong date. Well, more correctly, the day was right but it would be scheduled for next year. Or worse, 2 years ago.
Go thorugh Notes help or maybe call your IT people and tell them that you are having an issue with meeting invites sent from BlackBerry. Really no need to tell them that it is personal stuff. See if there is anything that they can tell you.
My wife's company fixed the problem on their system by switching to Outlook/Exchange.
