I think if you disable the new local indexing features in TB then it should start running fairly decently? I don't have mega large inboxes, but basically no real concerns with my normal inboxes which are around the 44K level at the largest and the remainder around 10K-15K Obviously it's a whole new problem to push out company wide configuration with the local indexing/download stuff disabled, but I think there is some ability to do this in newer versions? Good luck Ed W
