We migrated from Win 2003, Exchange 2003 Std to Win 2008 R2., Exchange 2007 last year. After users complained of not being able to send large attachments, I set the outgoing mail size limit to 20 megs (20480k) in the Exchange console.
Yesterday, a user complained of not being able to send a 15meg attachemnt. I looked at her sent mail and there is few lines of text, no graphics and a 15 meg PDF attachemnt. After sending it, she recieved a message from the exchange server that the email exceeds the max message lize allowed - #550 5.3.4 RoutingLimit
I went into the Exchange 2007 shell and ran Get-TransportSize and it says the MaxSendSize is 20 megs.
No other user is complaining. How do I resolve this?
