Validate open text responses in Microsoft Forms

Microsoft wants us to buy Power Apps to replace InfoPath but I work for a community college that cannot afford the Power Apps licenses so we have to buy a non-Microsoft solution instead.

Really? Not simple date validation?  Why is it taking 4 years to have a powerful form tool like Infopath?

Thanks Microsoft for failing to provide an appropriate powerful solution after retiring InfoPath.  Microsoft forms is so basic it's barely usable in any website. Google forms, Cognito forms are way more powerful and flexible.

Formatting, Design, Date/time validation, Visibility Rules, Conditions, regex (social security number, phone number), etc...

Steven_80 thanks for the quick reply! 

Azelin no, you can only enter one email address as the answer.

With the email restriction - does anyone know if more than one email can be entered?

"Is it simply checking for a text string followed by an @ sign, and then another string followed by a period and more text?"

Yes, it seems to checking only the format, rather than the validity of the actual email.

These additions are much needed, the ability to restrict the amount of text entered and email validation especially.

Is there an article available that describes the details of the email restriction?

Is it simply checking for a text string followed by an @ sign, and then another string followed by a period and more text?

Or is it advanced enough to check for common domains and returns an error if someone typo's a .ocm instead of .com?

I'm a big fan of the addition of restrictions and validation and hope Microsoft continues to include more features in this space.

I'm working with math faculty to create math equations (college algebra) in Forms that they can share with students. My goal is to have the instructor open a Form containing the equation. Students can collaborate in groups to find the answer and then provide the answer to the instructor through a response to an open response or a choice of answers. 

It would be great if the math equations could be written in Tex or LaTex. Is there a way to do this now, or is this a future feature? I can create Tex/LaTex equations in Poll Everywhere, but I hate Poll Everywhere. 

I know that I can also put the laTex/Tex question in a PowerPoint slide, and then show the response options in a Poll on the next slide, but that is an extra step that I don't want to take. 

when Microsoft Form has date and time question? this will be more useful for Microsoft Users.
