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

Re: TO Email TextField Validations


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")
