I read "The Case of the Mysteriously Deleted Appointments," March 2005, InstantDoc ID 45073, about how to get items that User A deletes from User B's calendar to stay in User B's Deleted Items folder, but I can't make it work. The Delegates page has no reference to the Deleted Items folder. Do I need to set the Write permission for Deleted Items in Exchange Server?

You don't use the Deleted Items page of Outlook's Tools, Options dialog box to set permissions on the Deleted Items folder, nor do you make the change using server tools. Instead, in Outlook, right-click the Deleted Items folder, choose Properties, then click the Permissions tab and set the permissions there.

You've brought to mind an important step that I omitted in the original tip. A registry value determines whose mailbox deleted items go to when another user deletes them. The Microsoft article "Items deleted from a shared mailbox go to the wrong folder in Outlook" (http://support.microsoft.com/?kbid=202517) explains that the relevant entry in Outlook 2002 is a DWORD value named DelegateWastebasketStyle in the HKEY_CURRENT_USER\Software\Microsoft\Office\10.0\Outlook\Options\General subkey. (For Outlook 2003, change the 10.0 part of the key name to 11.0; for Outlook 2000, change 10.0 to 9.0.) The DelegateWastebasketStyle value can have one of two values. The value 4 stores deleted items in the mailbox owner's Deleted Items folder. The value 8 stores the items in the Deleted Items folder of the person who deletes them. Set this registry value to 4 for the user who will be deleting the items.
