Service: Microsoft 365 Developer Program enrollment

Scenario: I'm attempting to join the Microsoft 365 Developer Program at https://developer.microsoft.com/en-us/microsoft-365/dev-program by clicking the "Join" button, but the enrollment process fails with an error message.

Error Message: "We're missing some information. Please add your first and last name to your Microsoft Account at https://account.microsoft.com/profile and try again later. It might take a few hours for the change to appear in the system. MS-CorrelationId: [Moderator note: personal info removed]

Environment:

  • Microsoft Account profile page shows my first and last name are already populated
  • My name originally contained a German Umlaut (ü), which was corrected by my administrator

Troubleshooting efforts:

  1. Verified that both first and last name fields are populated in my Microsoft Account profile (https://account.microsoft.com/profile)
  2. Tried accessing the enrollment page in incognito/private browsing mode
  3. Cleared all browser cookies and history
  4. Waited several hours after the name correction for system synchronization
  5. Issue persists despite these attempts

Result: The enrollment continues to fail with the same error message, even though my profile appears complete.

Questions:

  • Is there an additional synchronization required after special character corrections in Microsoft Account names?
  • Are there any backend caching issues that could prevent the Developer Program from recognizing updated profile information?
  • What additional steps can I take to resolve this enrollment blocker?

    Hi Marc Buettner

    Thank you for reaching out to the Microsoft Q&A Forum and for providing such a detailed description of your scenario.

    First, please note that this is a user-to-user support forum. Moderators, contributors, and external Microsoft employees participating here do not have access to Microsoft internal systems or the Microsoft 365 Developer Program backend. I’m therefore unable to check synchronization status or make any changes on the backend. My support here is limited to sharing general guidance based on available documentation and similar cases reported by other users.

    At the moment, I haven’t been able to find any official documentation confirming whether any additional steps are required after updating or correcting name information in a Microsoft Account profile, including cases where special characters were previously used, and there’s no publicly available information that explains this behavior in detail.

    However, I did come across a similar thread where another user experienced the same “missing first and last name” error during enrollment. In that case, the issue resolved on its own after some time without additional changes.

    Given that, you may consider allowing some additional time and trying again later. If the issue continues, you might also consider trying to enroll using a different Microsoft account to see if you’re able to complete the registration that way.

    Thank you again for your patience and for sharing the detailed troubleshooting steps you’ve already taken.

    It appears that you are encountering an issue with the Microsoft 365 Developer Program enrollment due to a missing first and last name error, despite having populated these fields in your Microsoft Account profile. Here are some insights regarding your questions:

    1. Known Delays or Synchronization Issues: There can indeed be delays in the system recognizing changes made to your Microsoft Account, especially after corrections involving special characters like German Umlauts. It may take several hours for the updates to propagate through Microsoft's systems.
    2. Backend Caching Issues: It's possible that there are caching issues on the backend that could prevent the Developer Program from recognizing your updated profile information. This can sometimes happen if the system has not yet refreshed its cache with the latest account details.
    3. Additional Steps to Resolve the Issue:
      • Contact Support: If the issue persists after waiting for a reasonable time, consider reaching out to Microsoft support for assistance. They may be able to provide insights into any backend issues or help you with your account.
      • Try Different Browsers or Devices: Sometimes, using a different browser or device can help bypass any local caching issues.
      • Double-Check Profile Information: Ensure that there are no additional discrepancies in your profile that might not be immediately visible.

    Following these steps should help you move forward with your enrollment in the Microsoft 365 Developer Program.
