Size limits for email messages are controlled in a variety of places in Exchange 2007. Settings are placed globally at the transport level, on each individual send or receive connector, and at each individual mailbox. Your business needs should determine if you need to change these settings and at which location(s). In order to accomplish this successfully, you must know that more restrictive settings override less restrictive settings as you flow up the chain from individual mailbox settings to SMTP connectors and finally to global transport settings.  

Global Transport Settings

Get-TransportConfig displays global transport settings for all Hub and Edge Transport servers in the Exchange Organization. By default, there is a 10MB size limit on send and receive. This will override all other less restrictive message size limit settings set elsewhere.

NOTE: Exchange 2007 considers message submission to the store driver as a “send” operation. Therefore, if you are attempting to receive an email message on an SBS 2008 server from the internet that is greater than the MaxSendSize of the global transport configuration, delivery will fail

Get-TransportConfig | ft MaxSendSize, MaxReceiveSize

In a previous post, we looked at how the maximum recipients per message settings are treated differently by Exchange Server 2010/2007 and Exchange 2003/2000 when sending to Distribution Groups (read previous post “Distribution Groups and maximum recipients per message“).

Another commonly asked question is about message size limits and the inability to send messages that are apparently within the maximum sizes configured. Let’s take a look at the message size settings in different places.

Organizational limits: These apply to all Exchange servers in the Organization. You can set these using the Set-TransportConfig command from the Exchange shell:

Set-TransportConfig -MaxReceiveSize 40MB -MaxSendSize 40MB

For this issue, we can thinking in the following way to fix it.

1.Stop the outgoing mails under Server Name — Queues — Disable Outbound Mail

then delete all the outgoing email queue.

When importing a new certificate into Exchange 2007/2010, you might encounter a certificate error in Outlook 2007/2010. I have included a screenshot of the error I encountered with Outlook 2007 :

When you choose the View Certificate button, it brings up another window that shows you what certificate is in error. In this case, the certificate name is “mail.shudnow.net.”

So the million dollar question? Why the error?

Well, when we install a new certificate, there are a few tasks we want to do. Obviously, we install the certificate for a purpose. This purpose is till allow us to use Exchange services securely. So how do we enable Exchange to use these services? If you are planning to do a very simple configuration and do not care about external Autodiscover access, you do not need to use a Unified Communication Certificate.

So let’s say we have a simple regular common certificate. A certificate with a Common Name (CN) of mail.shudnow.net We install this certificate onto our Exchange box with its’ private key. In our case we were migrating so we did not have to request a certificate via IIS. We just exported it with its’ private key and imported onto the new box. We then assigned this certificate to IIS. Now I went to the Exchange Management Shell and enabled Exchange services to use this certificate. In order to do this, you must run the following commands:
