Missing Public Folders in Outlook

We run Outlook’97 on our clients connecting to an Exchange 5.5 server.

We use public folders on the server extensively which all the Outlook’97 clients can see apart from one user.
She can see and use some of the older public folders we have setup but when I setup a brand new one on the server all the Outlook’97 clients can see it automatically except her!

She uses Windows 95 and Office 97.
I’ve tried service packing Office 97 to the latest SR2b patch but still no joy.

Anyone any ideas on how she can get the list of all Public Folders like everyone else?
I’ve checked her Exchange service is installed OK and pointing at the correct server.
