SYMPTOMS

If a Microsoft Exchange Server user sends a meeting request to another user whose mailbox has exceeded the defined per-mailbox storage limitation and who also has a delegate defined with Editor permissions for Calendar and Tasks, the sender receives a non-delivery report (NDR) similar to the following:

From: System Administrator
To: User1
Subject: Undeliverable: Subject

Your message did not reach some or all of the intended recipients
Subject: Subject
Sent: dtg of sent item

The following recipient(s) could not be reached:

User2 on dtg

Either the message size exceeds the maximum allowed for the recipient or transport, or you have exceeded the storage limit on your mailbox.

MSEXCH:MSExchangeIS:Domain Name:Server Name

This hotfix contains new functionality that can resolve this problem through a registry parameter:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\MSExchangeIS\Parameter sPrivate

Value Name: Apply Mailbox Quota to Rules
Data Type: Reg_DWORD

If this value is not 0, messages sent by rules still have the mailbox quota checked. If the value is not present or is 0, messages sent by rules ignore the mailbox quota for sending messages. Applying the latest Exchange Server 5.5 service pack does not automatically add this registry value.

NOTE: If you set mailbox quotas to rules, there may be side effects. For example, if you set a forward and delete rule, it may result in data loss, and if you set meeting requests to go only to the delegate, neither may receive the request if the mailbox is over the limit.

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\MSExchangeIS\ParametersPrivate

Value Name: Apply Mailbox Quota to Rules Data Type: Reg_DWORD

If this value is not 0, messages sent by rules still have the mailbox quota checked. If the value is not present or is 0, messages sent by rules ignore the mailbox quota for sending messages. Applying the latest Exchange 2000 Server service pack or Exchange Server 2003 service pack does not automatically add this registry value.

NOTE: If you set mailbox quotas to rules, there may be side effects. For example, if you set a forward and delete rule, it may result in data loss, and if you set meeting requests to go only to the delegate, neither may receive the request if the mailbox is over the limit.
