Underscore in Azure Active Directory B2C

    Question

  • Hi,

    I have been told that Azure Active Directory B2C doesn't support emails that have an underscore before the at sign.

    For example, the address "foo.bar@domain.com" is valid, but "foo.bar_@domain.com" wouldn't be.

    I can't find anything confirming (or not...) this information in the current documentation.

    Is it true?

    Thanks for your help
