    What has happen to your developers? They have got some kind lazy -pills? Otherwise it is very hard to understand that why there are no compatibility for old server version. It should not be rocket science to add clients a check the server version and behaves like that. Hope you are not planning to share the pills with Office and Outlook teams!
