Hi,

I am able to retrieve the Offline Messages using "OfflineMessageManager". I followed the below mentioned steps.

On creating connection, I set setSendPresence() to false.This prevents login() to send "available" presence packet to server.

          connConfig.setSendPresence(false); // where connConfig is object of ConnectionConfiguration.
          XMPPConnection conn = new XMPPConnection(connConfig);
          // connect to XMPP Server then login.
          // Now retrieve the offline msgs using "OfflineMessageManager"
          // send presence packet to server.

Hope, this helps.
