Could not able to add "Add login account"

The Learn / certification profile sign-in and legal-name issues require Microsoft support; community users cannot directly fix profile data or back-end account links.

For this scenario, there are two separate needs:

1. Fixing the Learn / certification profile sign-in and email association
2. Correcting the legal name so it matches ID for Pearson VUE exams

Based on the available guidance:

1. A Learn or certification profile cannot be “migrated” or transferred from one identity to another. Instead, multiple login accounts (email addresses) can be linked to a single Learn profile, and profiles can be merged if there are duplicates.
   • See: “You cannot transfer from one Learn profile to another. You can link and merge Learn profiles” and “You can add email addresses to your Microsoft Learn profile.”
2. Legal name corrections for exam / certification use must be handled by official support, not by self-service alone.

Follow these steps in order:

1. Re-establish a single Learn profile with all needed logins
   1. Sign in to Microsoft Learn with the account that currently works.
   2. Go to the Learn profile management page and use Add login accounts to your Learn profile to add your official email as an additional login, instead of creating a separate profile.
   3. If there is already another Learn profile tied to that official email, use the merge profiles option so that both identities (personal and official email) point to one combined Learn profile.
2. Set the correct email for Learn communications
   1. After the logins are added/merged, open your Learn user settings page.
   2. Set the desired email address as the one used for communications.
3. Get help correcting the legal name for exam use
   1. For legal-name issues that block Pearson VUE exams (for example, name not matching ID), use the official certification/credentials support channel.
   2. From there, request a correction of the legal name on the certification profile so it exactly matches the ID that will be used at the test center.
4. If sign-in loops continue (“Please sign out and sign in with a different account”)
   1. Always start from a private/incognito browser session.
   2. Sign out of all Microsoft accounts in that browser.
   3. Sign in only with the account that owns the Learn profile, then add the other login from the Add login accounts page as described above.
   4. If the loop persists, contact Learn / credentials support and provide:
      • The email(s) you are trying to add as login accounts
      • That you previously deleted a profile and now cannot attach the official email
      • That you receive the repeated “Please sign out and sign in with a different account” prompt

Because exam admission depends on the certification profile and legal name being correct, use the credentials support channel before scheduling or sitting the Pearson VUE exam.
