Important This article contains information about modifying the registry. Before you modify the registry, make sure to back it up and make sure that you understand how to restore the registry if a problem occurs.

256986 Description of the Microsoft Windows Registry



SYMPTOMS
When a new public folder store is brought online, you may notice in the Queue Viewer that the local delivery queue is growing. If the public folder hierarchy is large, the messages in the local queue continue to grow and may take additional time to be delivered. In some cases, the messages may not be delivered. Messages are not queued if the server sending these messages is in a different routing group from the server with the new public folder store.



CAUSE
This problem occurs because when a new public folder store is brought online, mail is frequently routed to the server before the hierarchy can replicate. As a result, mail may be delayed or not delivered.



RESOLUTION
A supported hotfix is now available from Microsoft, but it is only intended to correct the problem that is described in this article. Only apply it to systems that are experiencing this specific problem. This hotfix may receive additional testing. Therefore, if you are not severely affected by this problem, we recommend that you wait for the next Exchange 2000 Server service pack that contains this hotfix.

To resolve this problem immediately, contact Microsoft Product Support Services to obtain the hotfix. For a complete list of Microsoft Product Support Services telephone numbers and information about support costs, visit the following Microsoft Web site:

http://support.microsoft.com/contactus/?ws=support

Note In special cases, charges that are ordinarily incurred for support calls may be canceled if a Microsoft Support Professional determines that a specific update will resolve your problem. The usual support costs will apply to additional support questions and issues that do not qualify for the specific update in question. The English version of this hotfix has the file attributes (or later) that are listed in the following table. The dates and times for these files are listed in coordinated universal time (UTC). When you view the file information, it is converted to local time. To find the difference between UTC and local time, use the Time Zone tab in the Date and Time tool in Control Panel. Date        Time   Version       Size     File name -- 22-Sep-2002 14:49  6.00.00.6329  372,000  Phatcat.dll



If you install the hotfix only on the server that has the new public folder store, you will not fix the issue. To fix the issue, you must apply the hotfix on all the servers that route the public folder routing messages.



WORKAROUND
To work around this problem, create a second routing group and move the new server to that group. Set up routing group connectors and let replication occur. After replication has occurred, move the new server back to the original routing group.

To create a second routing group, follow these steps:
 * 1) Open Exchange System Manager, expand Administrative Groups, and then expand First Administrative Group.
 * 2) Right-click Routing Groups, and point to New, and then click Routing Group.
 * 3) Type a name for the new routing group, and then click OK.
 * 4) Expand First Routing Group, and then click Members.
 * 5) Drag the server with the new public folder store from the First Routing Group to the routing group that you just created, and then wait for replication to occur.
 * 6) After replication has occurred, move the server back to its original routing group.



STATUS
Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article.



MORE INFORMATION
When the new server is introduced, its distinguished name is added to the msExchOwningPFTreeBL attribute of the administrative group's Folder Hierarchies - Public Folder object in Active Directory.

To configure the number of days that the routing engine bypasses the new public folder store, follow these steps.

Warning If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.
 * 1) Start Registry Editor (Regedt32.exe).
 * 2) Locate the following key in the registry:
 * 3) On the Edit menu, click Add Value, and then add the following registry values:

Value Name: IgnorePFTimeLimit

Data Type: REG_DWORD

Radix: DECIMAL

Value: Number of days the routing engine will ignore the public folder

Default: 2
 * 1) Quit Registry Editor.
 * 2) Restart the Internet Information Services (IIS) Admin service (IISAdmin).

Note The registry change only takes effect after you restart all IIS services.
