Need to restrict email address to have only one @ symbol in powerapps forms

[Kavya2]

hi @VDS_Mantra 

I am using below formula to validate an email in power apps forms but its not working. My motive is to throw error when some one enters in below format abc@gmail@yahoo.com

Kindly help !

If(And(IsMatch(DataCardValue7.Text,Email),Not(Find("(",DataCardValue7.Text)>0),Not(Find(")",DataCardValue7.Text)>0),Not(Find(",",DataCardValue7.Text)>0),Not(Find(":",DataCardValue7.Text)>0),Not(Find("<",DataCardValue7.Text)>0),Not(Find(">",DataCardValue7.Text)>0),Not(Find("[",DataCardValue7.Text)>0),Not(Find("]",DataCardValue7.Text)>0),Not(Find("\",DataCardValue7.Text)>0),Not(Find("@",DataCardValue7.Text)>2)),"Its a valid email address","Error! Enter a valid email address")

@Kavya2 try this ...

IsMatch(Result,"[a-zA-Z0-9._%+-]+@[a-zA-Z0-9.-]+\.[a-zA-Z]{2,}")

Hi @Kavya2 

You'll have to be more specific with your feedback.  The above uses a regular expression which you can test here:

I cannot create emails with multiple @'s using this.

When I used your solution in powerapps, its not allowing to save the formula itself. Error as below. Please help.

Hi @Kavya2 , you need to wrap the formula given by @DamoBird365  with if , something like
if(Not(IsMatch(Result,"[a-zA-Z0-9._%+-]+@[a-zA-Z0-9.-]+\.[a-zA-Z]{2,}")),"Enter Valid Address")

[Kavya2]

Yes, its worked now. 

Used the formula as below :

If(Not(IsMatch(DataCardValue5.Text,"[a-zA-Z0-9._-]+@[a-zA-Z0-9._-]+\.[a-zA-Z]{2,}")), "Error! Enter a valid email address", "Valid email address")
