Based upon the list of values returned by the server, the client should choose the highest version that they both support, and start using it. The client needs to send this version to the server in every POST request.
In this case, we recommend that the client uses the most recent version of the Exchange ActiveSync protocol that it supports. Some details of the response have been omitted and abbreviated with "…" in this example.
There is no specific server-side error code that indicates that the client used a more recent version of the protocol for the particular Exchange server. If the server responds with an HTTP error code "Bad request" , it may mean that the server does not support the Exchange ActiveSync protocol version that the client used. In this case, the client should attempt to communicate with the Exchange server by using the previous Exchange ActiveSync protocol version, and should continue this process using an earlier Exchange ActiveSync protocol version each time , until the server sends a success response.
Following this initial communication, the client should perform version negotiation periodically to determine if the Exchange ActiveSync protocol versions supported by the server have changed. Two scenarios may change the protocol versions that the server supports: server upgrades and server downgrades. Newer versions of Exchange Server support nearly all previous versions of the Exchange ActiveSync protocol the current exception is version 1.
