Few weeks ago I tried Thunderbird with IMAP account which has ~300k emails. It was painfully slow just to load emails list and view email. Let alone navigate the folders I want all the emails downloaded for offline search. I guess I would give this a try again and see how it goes. Meanwhile, I have been using eM client since a week and it is very prompt to view list, navigate folders, search and all. With eM client, I have read people complaining about mandatory forced updates even with the paid license.
