Symptoms

When you move several mailboxes from a Microsoft Exchange 2000 Server server to a Microsoft Exchange Server 2003 server, the synchronization of the rules for the mailboxes may be delayed. Therefore, the rules may appear not to work for some time after the mailboxes are move.

More information

Warning Serious problems might occur if you modify the registry incorrectly by using Registry Editor or by using another method. These problems might require that you reinstall your operating system. Microsoft cannot guarantee that these problems can be solved. Modify the registry at your own risk.

When you move the mailboxes from an Exchange 2000 Server server to an Exchange Server 2003 server, the rules are moved in a server-independent format. Eventually, the rules are converted to rule messages that appropriate for the new target server.

The synchronization of the rules occurs in a background process that fires periodically. A single mailbox is synchronized every time that the background process fires. This behavior occurs even if the following conditions are true:
  • There are several mailboxes that have successfully completed the move.
  • There are mailboxes that are ready to be synchronized.
After you install this hotfix, the synchronization of the rules for all mailboxes that have completed a move is faster.

By default, mailbox rules are synchronized every hour after you install this hotfix. However, you can modify the following registry subkey to change the synchronization time:
HKLM\System\CurrentControlSet\Services\MSExchangeIs\<name of server>\<private store GUID>\Rules Sync Retry Frequency
Collapse this tableExpand this table
Value TypeDWORD
Minimum60
Maximum2592000
Default3600


The value for this registry subkey is in seconds. The minimum value that you can use is 60 seconds (1 minute). The maximum value that you can use is 2,592,000 seconds (30 days).

Warning If you set the value to 1 minute to try to achieve the fastest possible synchronization time, you may actually cause the synchronization process to take longer. This behavior occurs because the average sized mailbox takes 2 to 3 minutes to move. Additionally, only those mailboxes that have completed the move can be synchronized.

If you find that the synchronization process is too aggressive after you install this hotfix, you can limit the number of mailboxes that are synchronized at a time. You can modify the following registry subkey to set a limit for the number of mailboxes that are synchronized at a time:
HKLM\System\CurrentControlSet\Services\MSExchangeIs\<name of server>\<private store GUID>\Rules Sync Batch Limit
Collapse this tableExpand this table
Value TypeDWORD
Minimum1
Maximum0xFFFFFFFF
DefaultAll the mailboxes ready to be synched.


The values of this registry subkey are based on the number of mailboxes that you want to synchronize at a time. For example, the value of 1 means that you want one mailbox synchronized every time that the synchronization process occurs. Additionally, the value of 0xFFFFFFFF is a special value that means that you want all the mailboxes synchronized during the synchronization process.

If the synchronization process does not work, you can modify the following registry subkey to set the number of times that the synchronization process is retried for a mailbox:
HKLM\System\CurrentControlSet\Services\MSExchangeIs\<name of server>\<private store GUID>\Rules Sync Retry Limit
Collapse this tableExpand this table
Value TypeDWORD
Minimum0
Maximum250
Default24


If the synchronization process does not work, the following event is logged if the diagnostic level for rules is set to medium or to maximum. However, this behavior only occurs if the reason for synchronization not working is that the mailbox move is still in progress.
Event ID: 1151 
Source: MSExchangeIS Mailbox 
Description: A rule synchronization error (1144) has occurred on Mailbox Store "database name". 
The mailbox folder is Top of Information Store\Inbox. 
The distinguished name of the owning mailbox is /O=organization/OU=organizational unit/CN=Recipients/CN=s140605. 
There are 24 of 24 retries remaining.
If the synchronization is successful, you receive the following Information event when you set diagnostic level for rules to maximum:
Event ID: 1154 
Source: MSExchangeIS Mailbox 
Description: Rule synchronization has successfully completed. 
The mailbox folder is Top of Information Store\Inbox on database "database name". 
The distinguished name of the owning mailbox is /O=organization/OU=organizational unit/CN=Recipients/CN=s140605.
Note This hotfix resolution is only for the Exchange Server 2003. Therefore, you can only use this hotfix for migration scenarios where the target or destination server is an Exchange Server 2003 server.
