Can't Send an attachment over 10mb WHY!!??

Now we're on to Exchange 2007 settings:

Open a Power Shell Command:
Type in get-transportconfig | fl *
I have already set my transportconfig to 30mb
Here is what it shows me.

MaxReceiveSize : 30MB
MaxRecipientEnvelopeLimit : 31457280
MaxSendSize : 30MB

To change these setting use the following commands:

Set-transportconfig -MaxReceiveSize
MaxReceiveSize the default value is Unlimited. You can change it to what ever with an an MB following it
Set-transportconfig -MaxReceiveSize 30mb

Set-transportconfig -MaxRecipientEnvelopeLimit
The default size is Unlimited. The valid input range for this parameter is 0 to 2147483647.

Set-transportconfig -MaxSendSize
The default size is Unlimited. You can change it to what ever with an an MB following it

Next we need to look at the receive Connectors. Now we did change this in the ADSI Edit, but we need to make sure exchange 2007 took the setting correctly.

Use the following commands:
get-ReceiveConnector
This will list all of your ReceiveConnector.

Take the complete name and enter it into this command.

get-ReceiveConnector -Identity "Receive Connector name" | fl *
Then look for MaxMessageSize, mine was set for 30MB which is correct.

Do this for all of your Receive Connectors

Next we need to look at the Send Connectors. Now we did change this in the ADSI Edit, but we need to make sure exchange 2007 took the setting correctly.

Use the following commands:
get-SendConnector
This will list all of your SendConnector.

Take the complete name and enter it into this command.

get-SendConnector-Identity "Receive Connector name" | fl *
Then look for MaxMessageSize, mine was set for "Unlimited" which is correct.
