Increase Receive Limit Exchange 2010 above 10mb – #550 5.2.3 RESOLVER.RST.SendSizeLimit.Org; message too large for this organization ##

When you try to receive mail that is over 10mb into an Exchange 2010 mailbox, the sender may receive this bounce back error.

#550 5.2.3 RESOLVER.RST.SendSizeLimit.Org; message too large for this organization ##

Your Exchange 2010 server may need a few settings changed if you want to receive mail of this size.

Due to the way Exchange routes emails we found the following settings helpful if you are using a facility such as popcon to download incoming mail.

  1. Organization Configuration ->Hub Tansport.
    Go to Global Settings -> Transport Settings
    Set the Maximum send and receive size to KB values that suit eg. 20480 for 20mb or 51200 for 50mb
    Exchange increase receiv
  2. Go to Server Configuration ->Hub Transport
    Go through the receive connectors one-by-one and right-click -> Properties
    Exchange Receive Connector
  3. Set the Maximum message size to a size that suits such as 20480 for 20mb and click OK. DO this for all the receive connectors unless you have a special one that you use for a certain purpose and needs to remain lower.
    Exchange Receive Connector

Now the larger messages from outside your organisation should get to their destination mailboxes in your Exchange 2010 Server.
