I upgraded recently from 15x to 16x. Now, webmail interface takes literally forever to load in browser. This is not a browser specific issue btw, I'm seeing this on all popular clients, eg firefox chrome ie. This is intolerable for a product touted as 'cutting edge'.
Also, anyone know when global search is being reinstated. 16x destroyed that very useful feature.
I'm having 16x buyer remorse :-/ How hard is it to downgrade?
