Exchange 2003/2007 attachment limits not working correctly
Posted on 2011-03-02
I am unable to send emails with attachments larger than 10MB between my Exchange 2003 and 2007 organizations. If I send between users on Exchange 2003 all is fine. If I send between Exchange 2007 users all is fine. if I send between the 2003/2007 users, I get the message below. I am using an SMTP connector between the two sites. Any ideas?
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.
<1domain.domain.com #5.3.4 smtp;552 5.3.4 Message size exceeds fixed maximum message size>
