 From MS-ASCMD (the protocol documentation):

"If the GetAttachment command is used to retrieve an attachment that  
has been deleted on the server, a 500 status code is returned in the  
HTTP POST response."

See above regarding the HTTP 500 response. Not sure why your getting  
the PHP error though, it should be throwing an exception - which is  
what triggers the 500 response to be sent.
