=IF(LEN(A3)-LEN(SUBSTITUTE(A3,"@","")) = 2,"True","False") -- if it has exactly 2 in any place
=IF(LEN(A3)-LEN(SUBSTITUTE(A3,"@@",""))= 2,"True","False") -- if it has exactly 2 consecutive in any place
=IF(LEN(A3)-LEN(SUBSTITUTE(A3,"@","")) >= 2,"True","False") -- if it has at least 2 in any place
=IF(LEN(A3)-LEN(SUBSTITUTE(A3,"@@",""))>= 2,"True","False") -- if it has at least 2 consecutive in any place
=IF(left(A3, 2) = "@@","True","False") -- if it has at least 2 consecutive at the start
=IF(right(A3, 2) = "@@","True","False") -- if it has at least 2 consecutive at the end
