I use Office 97 & Windows 98. Outlook won't let me add any more contacts to my address book without deleting some as it appears to be full. Is there a limit to the number of contacts you can have? How can I add more? Does Office 2000 give unlimited contacts in an address book? I also am frequently experiencing a 'Mapisp 32' illegal operation error when checking my e-mails as well as the messaging interface returning an unknown error which both combine to prevent me from downloading e-mails.
