Send/Recieve limit in Exchange 2010?

Hi,

I have followed a few articles to the word to set send/receive attachment limit in exchange 2010. I have managed to set the send limit and it is working as expected, but not the Receive limit.

I have one edge server and two exchange 2010 servers in a DAG.

organization send connectors set to 40mb
organization Global Transport settings set to 40mb (send and receive)

Server configuration for "default receive" connector set to 40mb for both servers.

Edge server default receive connector set to 25mb (see attached picture) please note I want incoming mail attachment to be 25mb. Currently I can only receive 17mb ??

Please can someone tell me what am I missing and explain the difference setting limits at organization level and server level. Also what does the "default client" receive connecters on both exchange servers is used for this is set to 1024 by default?

hope the above makes sense.

Thanks in advance!

Does anything come up in the event logs or do you have any other smart host in your environment that might have additional restrictions on attachment size?

25MB is the total size limit which is not the attachment size of 25MB.  The size limit includes all overhead details and the email itself. I'm unsure whether it is 25,000 bytes or 25 MB (25.600 bytes)

will - no I don't have any other smart host just an Edge server? and which event log should I be looking for?

David Johnson MVP- yes I understand that, I sent a blank email from my Hotmail account with just one attachment of 20MB and it failed? do I need to anything else on Edge server as I thought I don't really need to as its sync'd from HUB? does the attached picture make sense is that correct?

fixed, by increasing the receive connector on Edge server by another 4 mb to receive just over 20MB I had to set to 29MB on Edge receive connector.

Technically a smart host does the same thing as an Edge server. This is a node that sits in the DMZ which also control's mail flow. my comment ID: 40855067 should be accepted as the answer? No? What do you think?
