I don't think I'd consider this an indicator of the beta's stability, after all, it's a feature that was SUPPOSED to be there, and now they've finally got it working. When we migrated to Exchange 2003 at work from 5.5, we had a lot of users like Prathapml, with thousands of items in their deleted folders that they wanted to keep. We told them that we'd keep the messages on the old server, but not to expect that they'd remain. "They are deleted, after all," we told them. Few of them listened In any case, I'm sorry for your loss, Prathapml. Data loss like that is unpleasant.
