A message that exceeds the configured size limit is sent to a server that is running Exchange Server 2003

Article ID: 894795 - View products that this article applies to.

SYMPTOMS

Consider the following scenario. In Microsoft Office Outlook 2003, a user sends a message that exceeds the configured size limit on a server that is running Microsoft Exchange Server 2003. Although the message exceeds the configured size limit, the message is sent to the Exchange server if one of the following conditions is true:

Outlook is configured to use cached mode.
Outlook is configured to use offline mode.
Outlook is configured to use a personal folder (.pst) file as the delivery location.

When the Exchange server receives the message that exceeds the configured size limit, the Exchange server generates a non-delivery report (NDR) that has the original message attached. Then, Outlook 2003 downloads the NDR.

When a message that exceeds the configured size limit is sent to the Exchange server, you may experience the following behavior:

General performance issues occur on the Exchange server.
Excessive network bandwidth is used between Outlook 2003 and the Exchange server.
Excessive transaction logs are generated on the Exchange server.
Excessive database growth occurs on the Exchange server.

How to obtain the latest service pack for Office 2003

After you install Office 2003 SP2 on the Outlook clients, Outlook users experience the following behavior when they send messages. Note that the following behavior occurs when Outlook 2003 is configured to use cached mode, to use offline mode, or to use a .pst file as the delivery location:

If the Outlook user's mailbox exceeds the configured size limit, the message is not sent to the Exchange server. The Outlook user receives the following error message:
Task 'Microsoft Exchange Server – Sending' reported error (0x8004060C) : 'The message store has reached its maximum size. To reduce the amount of data in this message store, select some items that you no longer need, and permanently (SHIFT + DEL) delete them.'
Additionally, the Outlook user is prompted to use the Mailbox Cleanup Wizard.
If a message exceeds the configured size limit on the Exchange server, the message is not sent to the Exchange server. Additionally, the Outlook user receives the following error message:
Task 'Microsoft Exchange Server – Sending' reported error (0x80040610) : 'The message being sent exceeds the message size established for this user.'

To configure the size limits that are described in this article, follow these steps:

Use Exchange System Manager to configure the Prohibit send at (KB) limit, the Prohibit send and receive at (KB) limit, and the Sending message size limit.
Wait for the Exchange server caches that are described in the following Knowledge Base article to expire:
327378
(http://support.microsoft.com/kb/327378/ )
Exchange 2000 and Exchange 2003 mailbox size limits are not enforced in a reasonable period of time; fix requires Exchange 2000 SP3
When the Exchange server caches expire, restart Outlook so that Outlook recognizes the new limits.

MORE INFORMATION

Exchange servers that have hotfix 894795 applied expose two new read-only MAPI properties that contain size-limit information. The two newly exposed properties are the PR_PROHIBIT_SEND_QUOTA property and the PR_MAX_SUBMIT_MESSAGE_SIZE property.

PR_PROHIBIT_SEND_QUOTA = 0x666e0003

The limit at which a user can no longer send messages is represented in kilobytes (KB).

The value of the PR_PROHIBIT_SEND_QUOTA property is determined by the following process:
- If the user account is configured to use custom storage limits and neither the Prohibit send at (KB) limit nor the Prohibit send and receive at (KB) limit is configured for the user account, MAPI_E_NOT_FOUND is returned when you query the PR_PROHIBIT_SEND_QUOTA property. Additionally, no mailbox size-limit checks are performed.
- If the user account is configured to use custom storage limits and either the Prohibit send at (KB) limit or the Prohibit send and receive at (KB) limit is defined for the user account, the limit that is defined for the user account is used.
- If the user account is configured to use custom storage limits and both the Prohibit send at (KB) limit and the Prohibit send and receive at (KB) limit are configured for the user account, the lesser of the two values is used.
- If the user account is configured to use mailbox store defaults and neither the Prohibit send at (KB) limit nor the Prohibit send and receive at (KB) limit is configured for the mailbox store, MAPI_E_NOT_FOUND is returned when you query the PR_PROHIBIT_SEND_QUOTA property. Additionally, no mailbox size-limit checks are performed.
- If the user account is configured to use mailbox store defaults and either the Prohibit send at (KB) limit or the Prohibit send and receive at (KB) limit is defined for the user account, the limit that is defined for the user account is used.
- If the user account is configured to use mailbox store defaults and both the Prohibit send at (KB) limit and the Prohibit send and receive at (KB) limit are configured for the mailbox store, the lesser of the two values is used.
PR_MAX_SUBMIT_MESSAGE_SIZE = 0x666d0003

The maximum size for a message that a user can send is represented in kilobytes (KB).
The value of the PR_MAX_SUBMIT_MESSAGE_SIZE property is determined by the following process:
- If a Sending message size limit is defined for the user account, the value for the Sending message size limit is used.
- If no limit is defined for the user account, the organization-level Sending message size limit is used.
- If the organization-level Sending message size limit is set to No limit, MAPI_E_NOT_FOUND is returned when you query the PR_MAX_SUBMIT_MESSAGE_SIZE property. Additionally, no maximum-message-size checks are performed.
