Publish App using the free Student Developer Account

Hello guys,

I'm student and I use the free Microsoft Student Developer account from my high school. Currently, I am having truble publishing my apps in the Microsoft Store. I always get the following error message:


You are signed in as *** Die E-Mail-Adresse wurde aus Datenschutzgründen entfernt. *** which is not associated with a Partner Center account. If you believe this is an error, try deleting your browser cookies and then do one of the following:

• - Sign in with an Azure AD user account that is already associated with a Partner Center account
• - Sign in with a Microsoft account that is already associated with a Partner Center account
• - Sign in with a Microsoft account that you’d like to register for a new Partner Center account

So, I tried logging in using my private account but with this, I wasn't able to use my voucher-key for publishing in Microsoft Store.

The Azure Sponsorship Balance page tells me, I still have the 100$ credits.


How can I make my school account to allow the Store registration or my private account to accept the voucher-key?


Thanks for helping!
