Email Address Validation in Microsoft Forms
Unfortunately, In Microsoft Forms, Only Numbers are available as a restriction, and there is NO restriction option to validate the Email field in Microsoft Forms.
Alternatives to validate Email in Microsoft Forms
Instead, you have to use Microsoft Dynamic Customer Voice which is the new name of Microsoft Forms Pro and has many features over the free Microsoft Forms.

- Add a new Text question.
- Click on the three dots "
