I am assigned to implement sync text message with exchange server 2010sp1 for Android Exchange application. There are some messages in Message application, those messages assumed to be synced to the server. But I havent found any commands to sync the messages from client to the server. BTW, I allreay download the text messages from Server to Email Application by Sync command and Options with <Class>SMS</Class> There is a description of Add command in [MS-ASCMD].pdf The Add element cannot be used to add any e-mail items from the client to the server, or to modify the contents of the recipient information cache. If a client attempts to add e-mails to the server, or attempts to add items to the recipient information cache, then a Status element value of 6 is returned. Is it possible sync message from client to server? If possible, what is the command? Thanks advanced

ActiveSync is what Exchange uses.
