Exchange2010 mailbox size limits are not immediately valid for configuration changes

PS In addition, there is an alternative way to move mailboxes to another mailbox store, which allows the changes to take effect immediately.

Do not enforce mailbox size for a reasonable period of time limit Exchange 2007

Last modified theme: 2007-09-20

This topic describes the reason that mailbox size limits do not take effect immediately after a configuration change.

After the mailbox size limit is configured for a mailbox, the mailbox user can continue to send and receive messages even if the configured mailbox size is exceeded. The configured restrictions will be enforced after a period of time, but will not take effect immediately. Restarting the Microsoft Exchange Information Store service causes the configured restrictions to take effect immediately. Solving method

This problem occurs because the Microsoft Exchange Information Store service enforces mailbox size limits with cached mailbox configurations. The configuration changes will not take effect until the cache is refreshed. The default time interval for refreshing cached mailbox information is two hours.

To resolve this issue, change the refresh interval for the mailbox information cache by modifying the value of the reread logon quota interval for the Microsoft Exchange Information Store service in the registry. The value of the "Reread logon quota interval" depends on the directory service Access (DSAccess) cache and the mailbox information cache. Therefore, you must configure both the Cachettluser and the mailbox cache aging limit values.

Unresolved_token_val (exregistry) point: Setting the cache refresh interval to a very small value can affect the performance of your Exchange server. It is recommended that you set the time interval value for refreshing mailbox information to 20 minutes. Before you start

To perform this procedure, you must delegate the following roles for the account that you use:

The Exchange server Administrator role and the local Administrators group membership of the target server

For more information about the permissions, role delegation, and rights that are required to manage Microsoft Exchange Server 2007, see Permission Considerations. Step Use Registry Editor to configure the mailbox information cache refresh interval for the Microsoft Exchange Information Store service

Start Registry Editor and connect to the registry of the server on which you want to configure the Microsoft Exchange Information Store service.

Locate the HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\MSExchangeIS\ParametersSystem item.

To configure the time interval for refreshing mailbox size limit information, do the following:

Right-click ParametersSystem, select New, and then select DWORD value.

Name the new DWORD value "reread logon quota interval."

Right-click Reread logon quota interval, and then click Modify.

Under the Cardinality option, click Decimal.

In the Value data text box, enter a positive integer to specify the refresh interval (in seconds) for the mailbox information cache, and then click OK. The default value is two hours (7,200 seconds). The recommended value is 20 minutes (1200 seconds).

To change the aging limit for the mailbox information cache, do the following:

Right-click ParametersSystem, select New, and then select DWORD value.

Name the new DWORD value as the mailbox cache aging limit.

Right-click Mailbox Cache Aging Restrictions, and then click Modify.

Click Decimal for the cardinality option.

In the Value data text box, enter a positive integer to specify the age limit for the mailbox information cache (in minutes), and then click OK. The default value is two hours (120 minutes).

Locate the Hkey_local_machine\system\currentcontrolset\services\msexchange ADACCESS\INSTANCE0 item. If the registry key does not exist, use the following procedure to create the key:

Right-click MSExchange adaccess, select New, and then select items.

Name the new item INSTANCE0.

To configure the DSAccess cache refresh rate, do the following:

Right-click Instance0, select New, and then select DWORD value.

Name the new DWORD value Cachettluser.

Right-click Cachettluser, and then click Modify.

Click Decimal for the cardinality option.

In the Value data text box, enter a positive integer to specify the cache expiration interval (in seconds) for the user data object. The default value is 5 minutes (300 seconds). Important: Reducing this value can affect performance because Exchange Server will perform more Active Directory directory service lookups.

Close Registry Editor.

Restart the Microsoft Exchange Information Store service.
