Public Function GoodEmail(iEmail As String) As Boolean
GoodEmail = IIf(iEmail Like "*@*.*", True, False)
End Function
Formula
=IF(GoodEmail(A3)," ","Please Correct email, it appears to be invalid")
The reason for the regexp is the addition of the special characters check. When you use the * wildcard, you are really leaving the field open for anything to be used, and not all characters are valid in email addresses. Of course there are pros and cons to all solutions.
My post is a quick and dirty for normal data entry.
It would not work at all if the e-mail was being entered through other means. I am offering another way other than loading the regexp on each entry.
