Another user asked a question about the error "552 ms-office file containing VBA macros" back on the 7th of March, but the answer was not sufficient.
My server is rejecting incoming messages that contain Excel files and the sender gets the same message you see above, but I can't find out where that is configured or enabled on my server.
I have Exchange 2003, Symantec Enterprise with the Exchange add-on, and a Sonicwall firewall.
The Sonicwall is configured to reject VBS ant EXE attachments, but the message generated would be something else.
The Symantec scans for viruses, but should quarantine the attachment and still let the message through to the recipient with a warning message.
I see nothing in Exchange 2003 that would reject messages because of VBA scripts inside an attachment.
I need to get this fixed immediately. Tax season is a lousy time for users to scream at an accounting firm.
