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 feature, mailboxes on the new server will not be able to view new messages with delegate permissions.

You will notice, however, the message count will always reflect the correct number of messages in the delegate's Inbox. This specific feature is by design for View/Searches.



CAUSE
Using the Move Mailbox feature of Microsoft Exchange Server corrupts certain properties on search folders. This does not cause any corruption in messages or in the database but does change certain properties on search folders. A search folder is a View/Sort/Filter of any kind. It does not contain messages but, instead, contains pointers to messages.



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.

To work around this problem, perform the following steps:

 Open the Exchange Administrator program and connect to the server affected by this problem. Set information store maintenance to Always. This can be set from the IS Maintenance tab on the Properties page for the affected server. NOTE: If IS Maintenance is not set to Always, you will delay the deletion of the restrictions on views until normal maintenance is scheduled. From the server's Properties page, select the Diagnostics Logging tab. From MSExchangeIS, then Private, set Views to MAXIMUM.  Create the following registry value:

     HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\MSExchangeIS \ParametersPrivate Value Name: Reset Views Data Type: REG_WORD Value: 1

NOTE: The above registry key is one path; it has been wrapped for readability.  Stop and restart the information store service. This can be done by going to Control Panel and choosing Services.</li></ol>

In about 15 minutes or less, the Maintenance Thread will execute, and you will notice the Reset Views registry value has been set to 0. This tells Exchange it is time to delete the cached restrictions/views, no matter how old they are. Normally, IS Maintenance will delete a cached restriction after 8 days of non-use.

STATUS
Microsoft has confirmed this to be a problem in Microsoft Exchange Server version 4.0. This problem has been corrected in the latest U.S. Service Pack for Microsoft Exchange Server version 4.0. For information on obtaining the Service Pack, query on the following word in the Microsoft Knowledge Base (without the spaces):

MORE INFORMATION
After you perform the above workaround, it is important to note that the client application may appear slow the first time a user views a mailbox with delegate permissions. This is normal, because the View/Restriction must be recreated for the client.

After the information store service has been running for a while (about one hour), check the Application Event log for the following event:

<pre class="fixed_text">  Event ID: 1175 Source: MSExchangeISPrivate Description: Deleted 4458 unused restricted views.

After this process has been completed, the registry value (specified in step 4 above) will be set to 0. Then you should undo the changes made in steps 2 and 3 above (that is, reset the information store maintenance schedule and set Diagnostics Logging to NONE).

At this point, the delegates should be able to see all messages except Private messages.
