Calendar reminders not showing for a user in Outlook

[sidewinder]

We run Windows XP and Office 2007. Our receptionist has recently stopped getting popup reminders from her calendar, which isn't great because she has a LOT of appointments.

 

I've googled extensively, and although there is plenty on this, running the most common solutions (outlook /cleanreminders and outlook /resetfolders) do nothing, there are no error messages, and a new profile seems to make no difference.

 

As far as I know she is the only user experiancing it, they certainly work for me anyway. There are no errors displayed either.

 

Any other ideas as to what I can try?
