Ok, I can now re-enable the trigger after it get's disabled by the -ERR, and I can actually put something in the "Save to Folder:" line, but the files never make it there, even though the message is deleted. The only way I'm able to get the email file and attachment are to leave it at default folder, and navigage to the long path folder.
Also, the -ERR still disables the trigger.
FYI, I'm testing on Vista.
