Hello all,
I have Exchange server installed at my work, i just recently changed the global setting for unlimited sending/receiving email sizes. A few of our clients are unable to send or receive large documents over 10 megabytes still. While the message is sending, there are no errors, the larger then 10 meg. attachment gets sent out, but then a message from system administrator echos back saying basically, the email is too big and could not be sent to the recipient. Does anyone know what i would have to do to fix this?

Thank you-

Luke Repko
