e-mail issue

e-mail issue

Ma'am, Sir,
My email has not worked since Friday 7/21/2017. I keep getting this message thru the zoho webpage "Your account is being upgraded" Thru my microsoft outlook I only get a cannot connect message. Can you please help as this is the only e-mail accout I have used for years as I found ZOHO could not be beat by anyone else (Until now)
Thank you
