A free program from Microsoft that provides developers with the tools, resources, and sandbox environments needed to build solutions for Microsoft 365.
Dear @CRONOS SU,
Good day! Welcome to Microsoft Q&A forum!
Based on your description, I understand that you're unable to sign in to the Microsoft 365 Developer Program Dashboard and are receiving Error 41102 after your Microsoft 365 E5 Developer subscription expired. You've already tried browser troubleshooting steps and would like Microsoft to verify whether any account restriction, eligibility issue, or backend flag is preventing access, and whether you're eligible to rejoin the program and apply for a new Developer Sandbox.
To ensure this issue is reviewed by the appropriate team with access to Microsoft 365 Developer Program account records and eligibility systems, I recommend submitting a support request to the Microsoft 365 Developer Program Support team.
They are best equipped to investigate the Error 41102 sign-in issue, review the current status of your Developer Program account, and determine whether any account restriction, eligibility condition, or backend flag is preventing access to the Developer Program Dashboard.
Please visit the Microsoft 365 Developer Program portal and from there, sign in with your account and select 'Support' and provide details about the issue, including:
- The account used to sign in to the Developer Program
- The Error 41102 message
- The approximate date and time the issue occurred
- The troubleshooting steps already performed (such as clearing cache/cookies, using InPrivate mode, and trying different browsers)
- Screenshots of the error, with any sensitive information removed
You can also follow the instructions from this article: Get Help with the Engage Center Platform
Once your ticket has been submitted, the support team will be able to review your case in more detail and provide further assistance.
If you can't find the option to submit a support issue, please try to find the related hotline number to call the frontline and reach out to Support team so that they could check with this: Technical or Sales support phone numbers (for Work account, scroll down to find your region's number)
If you're able to access Engage Center, kindly submit a ticket there as suggested above.
I appreciate your patience and understanding!
