Since you upgraded my account the search mail function has never worked. I am tired to being unable to search my mail. As a paid customer, I feel I deserve to be able to use this basic function, and if you cannot fix it I will take my business elsewhere. I have already closed my business account, and moved my domains elsewhere. Are you going to drive me away completely with your broken email?

It is only retrieving results from Sent folder. and sometimes not searching the body of the email, either
