I have tried using the steps provided in a Microsoft KB and they did not resolve it. I tried:
outlook /cleanreminders outlook /resetfolders
They did not fix it. The machine is running Outlook 2007 on Windows XP Pro. I have tried restarting the machine and I checked for processes running in the background. The outlook web access shows the reminders but they do not appear on the machine at hand. I have not tried getting the user to log into another machine to see if they work or not as she is away for a few hours.
Does anyone have any suggestions?
