After upgrading from Outlook 97 to Outlook 2000, and then turning off Microsoft Schedule+ as your primary calendar, you are not able to add delegate permissions to your Outlook calendar.
Choosing the option to Use Schedule+ as my primary calendar while running Outlook 97, sets a key in the Office 8.0 registry values called, UseSchedPlus. Among other things, this key keeps you from setting delegate permissions to your Outlook calendar.
When you upgrade to Outlook 2000, setup installs a new set of registry entries for Office 9.0. When you turn off the option to use Schedule+ in Outlook 2000, the Office 9.0 key is turned off, but the Office 8.0 value for the UseSchedPlus key remains on, therefore delegate permissions to your Outlook calendar are still unavailable.
To resolve this problem, obtain Microsoft Office 2000 Service Release 1/1a (SR-1/SR-1a).
To obtain SR-1/SR-1a, click the article number below to view the article in the Microsoft Knowledge Base:
