Dynamics Portal: Forgot Password User ID Error when Validating by email

(0) ShareShare
ReportReport
Posted on by 215

We are using the portal site setting "Authentication/Registration/LocalLoginByEmail" to have users use their email address to log into the portal. For most part this has worked well for everyone; however, I have had multiple users getting this error when resetting their password: 

  • User name '' is invalid, can only contain letters or digits.

For some reason even though we have set to validate from email address on random accounts it appears to not like the fact that the @ and . are in the "username" 

Anyone have any ideas?

    Hi partner,

    Did you check the "username" field in the contact form in UCI?

    If this issue still exists, you could raise a ticket to Microsoft Team to ask the engineers help you resolve the issue in server-side. And at the same time, you could use another way to reset the users' passwords.

    Hope it helps.
