IMPORTANT: This article contains information about editing the registry. Before you edit the registry, make sure you understand how to restore it if a problem occurs. For information about how to do this, view the "Restoring the Registry" Help topic in Regedit.exe or the "Restoring a Registry Key" Help topic in Regedt32.exe.



SYMPTOMS
After you use the Move Mailbox command in the Microsoft Exchange Administrator program, the Reminders dialog box for scheduled appointments fails to display using Outlook 97 clients.



CAUSE
Outlook 97 introduced some new MAPI properties. These properties were not being correctly mapped to the older properties that actually contained the Reminder information after the mailbox was moved to the new server.



WORKAROUND
WARNING: Using Registry Editor incorrectly can cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that problems resulting from the incorrect use of Registry Editor can be solved. Use Registry Editor at your own risk.

For information about how to edit the registry, view the "Changing Keys And Values" Help topic in Registry Editor (Regedit.exe) or the "Add and Delete Information in the Registry" and "Edit Registry Data" Help topics in Regedt32.exe. Note that you should back up the registry before you edit it. If you are running Windows NT, you should also update your Emergency Repair Disk (ERD).

To clean your reminders so they are displayed when they normally should be, follow these steps:

 Apply the latest service pack for Microsoft Exchange Server version 5.0 on an Exchange Server 5.0 computer. For information on obtaining the service pack, query on the following word in the Microsoft Knowledge Base (without the spaces):

NOTE: The fix that allows you to clean your reminders has been implemented only in the Administrator program for Exchange Server 5.0. However, the Exchange Server 5.0 Administrator program can be used to clean your reminders on an Exchange Server 4.0 computer.

 Start the Registry Editor (Regedt32.exe).  Locate the following key in the registry:

     HKEY_CURRENT_USER\Software\Microsoft\Exchange\MSExchangeAdminCommon   On the Edit menu, click Add Value, and then add the following registry value:

     Value name: CleanReminders Value type: REG_DWORD Value data: 1  Quit the Registry Editor.</li> Start the Administrator program. To do so, click Start, point to Programs, point to Microsoft Exchange, and then click Microsoft Exchange Administrator.</li> In the left pane, select the appropriate Recipients object. In the right pane, select the desired mailboxes.

NOTE: The users should not be logged on to the server when you perform these steps.</li> On the Tools menu, click Clean Mailbox. Click OK, and then click OK again.</li> When Clean Mailbox finishes, start Outlook and log on to the server using the mailbox that was experiencing this problem. When you do so, the Reminders folder is rebuilt and your reminders should be displayed.</li></ol>

NOTE: When the CleanReminders registry value is set to 1, the Clean Mailbox command only cleans the Reminders folder for the selected mailboxes. The Clean Mailbox command does not delete any messages.
