Delivery Restrictions set at the user level in Exchange 2003 not behaving as expected for internal emails. We've set delivery restrictions at the user level only for both the sending message size and receiving message size. Most of our users have sending and receiving restrictions of 15MB. Some users have sending and receiving restrictions of 50MB and a very small handful are unrestricted. Here's my problem: When a user with a 50MB limit sends an 18MB email to a user with a 15MB limit, that 15MB limit user is receiving the email. Shouldn't the user withthe 50MB limit be receiving an NDR instead? Why is the user with the 15MB recieving limit receiving that large email? Is this the way it should be behaving? When a user with a 15MB limit sends an 18MB email to a user with a 50MB limit, that 50MB limit user receives the email. Shouldn't the user with the 15MB limit be receiving an NDR? Why is the user with a 15MB limit able to send to a user with a 50MB limit? Is this the way it should be behaving? BTW - we are only experiencing this with large internal emails. Large emails being sent to, or received from, the Internet are behaving as expected.

Hi pls read the following link: exchange 2k and exchange 2k3 message restrcition: http://technet.microsoft.com/en-us/library/aa996221.aspx how to set size limits for messages in exchange server 2k and2k3: http://support.microsoft.com/kb/322679/en-us managing message size limits for exchange server 2k7: http://technet.microsoft.com/en-us/library/bb124345.aspx SMTP conenctor of exchang 2k/2k3 restrictions need to modify registry to effective impact http://support.microsoft.com/kb/277872/en-us for example for exchange server 2k/2k3: Examples of effective size limits Example 1 In this example, the following size limits have been configured: The global setting is set to 5 MB. The Exchange SMTP connector is set to 3 MB. The SMTP virtual server is set to 4 MB. The user mailbox setting is set to 2 MB.Because of these settings, users in the Exchange 2000 or Exchange 2003 organization can send and receive messages that are a maximum of 5 MB. Users can send messages through the connector that are a maximum of 3 MB. All mail that passes through the SMTP Virtual Server (sending or receiving) is limited to 4MB. The individual user, whose mailbox setting is 2 MB, is also limited to sending and receiving messages that are a maximum of 2 MB. Example 2 In this example, the following size limits have been configured: The global setting is set to 2 MB. The Exchange 2000 SMTP connector is set to 5 MB. The SMTP virtual server is set to 2 MB. The user mailbox setting is set to 3 MB.The global setting is 2 MB. Therefore, all the users who are using the default global setting in the Exchange 2000 Server organization or in the Exchange Server 2003 organization are limited to sending and receiving messages that are a maximum of 2 MB. If an individual user has a mailbox setting of 3 MB, that user overrides the global setting. hope it helps -Jack

Dear customer: In order to better troubleshoot the issue, please help collect the following inofrmation: 1. What is your Exchange server SP version? 2. Did the problematic user send e-mail via Exchange account (MAPI)? If no, please try to create a new Outlook profile with Exchange account, and check the effect. 3. Open ESM, navigate to global settings- Message Delivery, right click Message Delivery and select properties, click defaults tab, send the screenshot of it to v-rocwan@microsoft.com for analyze. 4. Open ADUC, navigate to the user whose limit is 50M, right click it and select proerties, click Exchange general tab, and click delivery restrictions, send the screenshot of it to me. 5. Repeat step 4 for the users whose limit is 15M and 18M respectively, and send the screenshots of them to me. 6. Do all users belong to one routing group? 7. Do all user mailboxes resides on one Exchange server? Note: when you send e-mail to me, please let me know the subject of the post. Thanks for your cooperation. Rock Wang - MSFT
