TO Email TextField Validations


Trying to validate Text Field so I could use it to Pick Recipient Email address. I manage to validate it using regular Expressions however unable to finish it as I want.
regularExpression I have used is. 


This work fine for the email part but when I try to add more addresses in same text field i.e.; ...
I am getting mismatch; any idea how to validate all email addresses and to make it mandatory to use ; if there is more than one email address OR if replace [SPACE] with ;SPACE to format it properly as user can send emails to multiple recipients this way.

Thank you

Regular expressions are actually not necessary to validate an email in PowerApps.  You can do this in a simpler way


IsMatch(“yourname@your”, Match.Email)


To determine if all emails in a string are valid you can use this comparison.  It asks: how many valid emails and does it match the total emails supplied.


CountRows(Filter(AddColumns(Split(“;”, “; “), “IsEmail”, IsMatch(Result, Match.Email))), IsEmail=true)=CountRows(Split(“;”, “; “))

I used regular Expression and This is what I did

IsMatch(EmailTextField.text,"^(([a-zA-Z0-9_\-\.]+)@((\[[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.)|(([a-zA-Z0-9\-]+\.)+))([a-zA-Z]{2,4}|[0-9]{1,3})(\]?)(\s*;\s*|\s*$))*$"),"Use ' ; ' if adding multiple email address", "Invalid Email Address")
