I have a customer on Outlook 2003 clients, Exchange 2003 server, who has created 4 shared contacts lists. Some users can access all 4, others can only access a couple of lists, and a handful can't access any of them.

The lists are shared to 'everyone', and some of the users who can't access are listed as editors or owners.

The error received is that there is not enough memory on the server to complete the request. To me this seems like a client side issue, not a server issue. Any ideas?
