Hi, I'm using Exchange 2000. we have set the i/c & o/g attachment size limit to 5MB. when somebody is trying to send a message with 2.3MB it is bouncing back with an error. I checked SMTP properties and the mailbox properties , everywhere it is showing 5MB size limit. After changing all the limits, I'd restarted my server aswell. Not sure where I missed some settings. Please help. This is the error I get - our message did not reach some or all of the intended recipients. Subject: FW: Mail delivery failure Sent: 10/9/2003 9:22 PM The following recipient(s) could not be reached: Gopi Krishna N on 10/9/2003 9:34 PM This message is larger than the current system limit or the recipient's mailbox is full. Create a shorter message body or remove attachments and try sending it again. <servername.domain.com #5.2.3> Thanks Gopi
