Exchange 2007 Message Size Limit

In Microsoft Exchange 2007 you have 10Mb limit for messages size. To increase this limit, you have to do several configurations.

After setting the single user mailbox limit from the GUI (Exchange Management Console), go to the shell (Exchange Management Shell) and type the commands below. Uppercase commands print the configuration parameters, "set" commands modify the values.


GET-TRANSPORTCONFIG

set-transportconfig -MaxReceiveSize VALUE
set-transportconfig -MaxRecipientEnvelopeLimit VALUE
set-transportconfig -MaxSendSize VALUE


GET-RECEIVECONNECTOR LIST

set-receiveconnector -MaxMessageSize VALUE (if requested, the "identity" are listed by the upper command)


GET-SENDCONNECTOR LIST


set-sendconnector -MaxMessageSize VALUE (if requested, the "identity" are listed by the upper command)



VALUE can be expressed, for example, like 10000 or 10MB
