Hello

I am Abdal and I would be glad to help you with your question.

Error code E06 in Volume Licensing Service Center (VLSC) usually indicates a problem with the Microsoft Account used to access the portal. Here are some steps you can take to fix the issue:

Make sure you are using the correct email address associated with your Volume License Agreement.

Reset your password for the Microsoft Account associated with your VLSC account.

Clear your browser's cache and cookies and try logging in again.

Try using a different browser access the VLSC.
