XADM: Meeting Requests Are Not Delivered if Recipient's Mailbox Has Exceeded the Storage Limit and Has a Delegate Defined

ID: Q217139

The information in this article applies to:

Microsoft Exchange Server, version 5.5

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

CAUSE

The Exchange Server information store does not allow Inbox Rules to start when the mailbox size limit has been exceeded.

RESOLUTION

To resolve this problem, obtain the latest service pack for Exchange Server version 5.5. For additional information, please see the following article in the Microsoft Knowledge Base:

Q191014 XGEN: How to Obtain the latest Exchange Server 5.5 Service Pack

The English version of this fix should have the following file attributes or later:

Component: Directory Synchronization

File name	Version
Gapi32.dll	5.5.2543.0
Mdbmsg.dll	5.5.2543.0
Store.exe	5.5.2543.0

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.

STATUS

Microsoft has confirmed this to be a problem in Microsoft Exchange Server version 5.5. This problem was first corrected in Exchange Server 5.5 Service Pack 3.
