Thanks. We'll let you know when a new response is added.

In the Exchange Management console under Organization Configuration Click Hub Transport. Click the Global Settings tab and double click your Transport Settings. Is there a maximum send and receive size set there? Also check your send connector and see if a maximum message size is set there.

    Open your EMS and use the command:
    get-receiveconnector | select identity,maxmessagesize
    to get the size limit on all your receive connectors.. Use
    set-receiveconnector "Connector Name" -maxmessagesize nnMB
    to set the desired size on a specific receive connector (Connector Name). Replace the nn with the number representing desired size limit.

    OK, try this, run the second command I gave you phrased like this:
    set-receiveconnector default -maxmessagesize 50M
    Then check with the original to see if it has taken. Finally either bounce all the Exchange services or restart the server.

    If you are still having a problem, there are two places to look in EMC for the connector size. First look at Hub Transport in Organization Configuration. Open the Send Connectors tab, then, on each connector you may have, right click and select Properties. On the General Tab ensure that the box is checked for Maximum message size along with there being a size in the box for it. The other is also in Hub Transport, but this time under Server Configuration. You will see all your send & receive connectors listed in the bottom half of the page. Again right click on the pertinent connectors, and select properties. You'll see the same line near the bottom of the General tab, but without the check box. Ensure the number is correct here also.

    The problem go on, I've restarted the server but it's not possible receive attachments greater than 4,X MB "This is an automatically generated Delivery Status Notification THIS IS A WARNING MESSAGE ONLY. YOU DO NOT NEED TO RESEND YOUR MESSAGE. Delivery to the following recipient has been delayed: xxxxx@xxxxxxxxx.com Message will be retried for 2 more day(s) Technical details of temporary failure: Connection was dropped by remote host (SENT_MESSAGE)" :-(

    Thanks Rechil, I've read the article and I think that the problem is with connectiontimeout parameter, because the internals email with attachments upper than 5MB hasn't any problems. I'm going to change the value of this parameter for to test it. Regards

    November 30 post shows an NDR with a connection timeout. You need to look into your protocol logs to find the entries from the communication that ended with the NDR. This may show you where the problm may lie.
