How to troubleshoot Microsoft Entra sign-up errors

[!INCLUDE applies-to-external-only]

Microsoft Entra sign-up logs help you troubleshoot sign-up failures for users of applications in your external tenant. This article describes how to isolate sign-up failures and understand the root causes.

Sign-up error codes

To research information about specific sign-up error codes, you can use the following tools:

The following error codes are associated with sign-up events, but this list isn't exhaustive:

  • 50181: Unable to validate the OTP.

    • This error code appears when the one-time passcode the user is trying to enter can't be validated.
    • The user should request a new one-time passcode.

  • 50182: OTP is already expired.

    • This error code appears when the one-time passcode the user is trying to enter is expired.
    • The user should request a new one-time passcode.

  • 1002027: Some of the collected attributes were invalid.

    • One or more attributes entered by the user during sign-up weren't in a valid format.
    • The user should reenter the attributes.

  • 399279: User creation failed during self-service sign-up.

    • The user's account couldn't be created.
    • The user should retry the sign-up process.

The following codes are not actual errors. They indicate expected interruptions that occur due to the interactive nature of the sign-up process.

  • 1002013: User is prompted to enter Email One-Time-Passcode to verify ownership of email address.

    • This is an expected part of the signup flow, where a user is prompted to enter the one-time-passcode emailed to them to verify ownership of email address.

  • 50140: User is prompted with option to 'Keep me signed in' during the sign-in following sign-up.

    • This is an expected part of the sign-in flow, where a user is asked if they want to remain signed into this browser to make further sign-ins easier.

If an issue persists despite taking the recommended course of action, open a support request. For more information, see how to get support for Microsoft Entra ID.
