A colleague changed his e-mail address about a couple of years ago.
Although I deleted his old Smartsheet account linked to his old e-mail address, when the colleague logs in he is still redirected to the old account I had deleted.
Old e-mail address with end part: .ext@cefla.it
New e-mail address with ending part: @cefla.co.uk
