Custom Validation in Forms

Hi, I have a text field in forms, and I was wondering if I could do some kind of custom validation or multiple validations (i.e. 1 AND (2 OR 3)) on that text field.

I feel like I have seen custom validation functionality (e.g. RegEx) before but this is not available in my version of Microsoft forms.

Suppose it is only available in another version of Forms (i.e. Pro), is it possible to request for this functionality to exist in the normal version?

 

The reason why I cannot use power automate or what not to post validate is because I do not collect E-mails (Not because I don't want to, but because my users simply don't have one or do not maintain one).

    Custom validation is not available in Forms. Regex for example was in the old Forms Pro (now called Customer Voice in Microsoft Dynamics) but for some reason was never implemented in standard Forms.

    Feature requests can be made on the official Microsoft Feedback Portal. The requests related to validation in Forms are at https://feedbackportal.microsoft.com/feedback/search/0ab9de26-ff1b-ec11-b6e7-0022481f8472?q=Validation

     

    However, Microsoft never seem to act on the requests!
