Outlook 2000 - open other users folders not working

[tpluskota]

Every time I open another users folder in Outlook i.e. Calendar, it saves that user in a history where I should be able to click on it in futrue. This works and I build up a list of freqently visited folders..then all of a sudden it starts opening random folders when I click on any of these links, event thou it will say user1 Calendar it will infact open user 9's calendar...??
Has anyone seen this before??
