XCLN: Outlook 2000 Delegate Calendar Permissions Unavailable After Disabling Schedule+ as Primary Calendar

If you upgrade to Outlook 2000 from a previous version of Outlook that uses Microsoft Schedule+ as the primary calendar, you may be unable to configure calendar permissions for delegates after you disable the use of Schedule+ as the primary calendar.

When you click Options on the Tools menu, click Delegates, and then try to set up calendar permissions, the permission list is unavailable, which prevents you from establishing calendar permissions for delegates.

This problem can occur because if you upgrade to Outlook 2000 and continue to use Schedule+ as your primary calendar, and then convert to use the Outlook calendar as your primary calendar, the UseSchedPlus registry value is changed from 1 to 0 in the Office 9.0 key, but the corresponding Office 8.0 entry is not changed from 1 to 0.

Outlook 2000 disables the Schedule+ option in the following registry key: However, the following registry key remains enabled:

Change the following Office 8.0 registry key to disable the SchedPlusOption value by changing it to 0:

Microsoft has confirmed that this is a problem in Microsoft Outlook 2000.
