Can not get user logged in to Exchange

[merk]

We have a laptop user who can not get connected to exchange. When I add the exchange account, everything seems to go as normal. In outlook, the user has the exchange account and the public folders. However, when trying to access these folders in outlook, the access is denied (folder not available).

Any help would be appreciated!
