Error description

  • The attachment sync error was valid in this case and the correct
    500 Server Error response code sent as per the ActiveSync
    protocol.  However more often then not Apple devices re-sync all
    data when they recieve a 500 server error response code.
    Instead we will send a 503 server busy response code which Apple
    devices handle much better.
    
    The attachment sync error for reference is:
    
     Error(404)=Entry not found in index.
    
    Which basically means the e-mail has already been deleted or it
    has been moved to a different folder.  Its a timing scenario
    that should resolve on the next device sync, but should not
    result in the device resyncing all data.
    

Local fix

  • NA
    

Problem summary

  • The error in this case was valid, the attachment had been
    removed from the e-mail.  However Apple devices do not handle
    the ActiveSync specified 500 error code very well and often will
    resync all data when encountered.  The fix in this case is to
    return a 503 (Server Busy) error code which the device handles
    much better.  This is only an issue with the Native Apple mail
    clients on iOS.
    

Problem conclusion

  • The IBM Traveler server has been updated to return a server busy
    503 response code to work around Apple device behaviors.
    

Temporary fix
