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.
