Hi All,Currently my Exchange Server 2007 only can Send/Receive an email not more than 5MB. After configure the Organization Configure-->Hub Transport-->Send Connector to Maximum 20MB and all the user mailbox send & receive email to maximum 20MB, but now only internal user to internal user can send/receive email max to 20MB, and internal user also can't send an email more than 5MB to external. If external people want to send an email more than 5MB also will not reachable to us. I don't know what is the problem, please advice.Thank you very much.

As this is only for mails to external domains, so check the size limits you need to check on send connector and also on the FW (if there is any limit set over there.)check this out for better understanding http://technet.microsoft.com/en-us/library/bb124345(EXCHG.80).aspxRaj

Make sure to configure the Transport Settings (under Organization Configuration --> Hub Transport --> Global Settings) If you still get an error, please post the NDRElie B. MCITP: EMEA|EA|SA; MCTS: Microsoft Exchange Server 2010, Configuration; Blog: http://blog.elieb.info

Thanks All.The Transport Settings (under Organization Configuration --> Hub Transport --> Global Settings/Send Connector) already set to 20MB.I am try using my hotmail account send an email(7.6MB) to my exchange but not reachable. NDR: This is an automatically generated Delivery Status Notification. Delivery to the following recipients failed.Any idea on this?

Can you try to increase the size of the receive connector? If failed, please post the full error.Elie B. MCITP: EMEA|EA|SA; MCTS: Microsoft Exchange Server 2010, Configuration; Blog: http://blog.elieb.info

Hi,How about your question? Any update?Do you have a pure exchange 2007 server organization, or exchange 2007 and exchange 2003 coexistence?Is there any error code in the NDR? Do you have an edge server?Frank Wang

Hi All, I dont have an edge server and also set MAX size 20MB in the receive connector. My friend try to send me an email with 16MB, but get the below NDR:Delivery has failed to these recipients or distribution lists: 'leeyl@xxxx.com'This message exceeds the maximum message size allowed. Microsoft Exchange will not try to redeliver this message for you. Please make the message smaller -- by removing attachments, for example -- and try sending it again, or provide the following diagnostic text to your system administrator.

Can you try with a small attachment size, 12MB for example. Who is the first checkpoint for your incoming mails?Elie B. MCITP: EMEA|EA|SA; MCTS: Microsoft Exchange Server 2010, Configuration; Blog: http://blog.elieb.info

The same problem with 12MB.What is your meaning of "the first checkpoint for your incoming mails"? How to check it out??

Elie mean to say is whats the first device where your incoming mail will hit , can be a FW or some kind of anti spam or AV device.Raj

Get information about Send\Receive limit, usind this cmdlets in EMS:Get-TransportConfig (check value of MaxReceiveSize)Get-ReceiveConnector "Connector name" |fl (check MaxMessageSize)Get-Mailbox |fl (check MaxReceiveSize)http://okrylov.wordpress.com

Hi,How about your question? Any update?please also check the attribute as Henrik said:http://social.technet.microsoft.com/Forums/en-US/exchangesvrtransport/thread/18104c86-bd19-4254-8f57-0dfe99fb884bFrank Wang

Hi Frank,checked the ADSIEdit but everything is ok.Hi Elie,first point should be the Cisco Firewall ASA5510 then go to the Symantec Mail Security and finally go to the Exchange.Hi Oleg,all already set to 20MB.Is is possible the FW problem?

It can be. Looks like you have checked every thing that is possible on exchange.Please ask your FW enggs. to check the FW or any other device which is the first point where the external emails hit.Raj
