Hi, Scott
Welcome to Microsoft´s Community.
As we understand from your post, you want to change the email associated.
Due to improvements in security processes, updating your personal Microsoft account (MSA) must now be done via your Learn profile. To protect your privacy, we cannot view or update this information from our end.
By design, your Learn profile can be associated with one personal Microsoft account (MSA) and up to five work or school accounts (AAD) at a time. This limit cannot be exceeded.
Additionally, previous services related to Certification profiles, such as profiles merging and email change are now self-assisted by users.
This means that, to update the personal Microsoft account (MSA) associated with your Learn profile, you must first add a work or school account (AAD) to your profile. This will allow you to remove and replace your personal account.
To update the personal Microsoft account (MSA) associated with your Learn profile, please follow the steps below:
If you have a work or school (AAD) account associated with your Learn profile:
Please visit Microsoft Learn.
Sign in using your work or school account (AAD).
Click on your user icon, located at the upper right corner of the screen, and select "Settings."
Under the "Account management" section, remove your personal Microsoft account (MSA).
After removing your personal account, click "Add account" and sign in using your preferred Microsoft account (MSA).
If you do not have a work or school (AAD) account associated with your Learn profile:
Please visit Microsoft Learn.
Sign in with your current personal Microsoft account (MSA).
Click on your user icon, located at the upper right corner of the screen, and select "Settings."
Under the "Account management" section, select "Add account."
Sign in using your work or school account (AAD) to add it to your Learn profile.
Sign out of Microsoft Learn.
Sign into Microsoft Learn using your work or school account (AAD).
Return to the "Account management" section to remove your personal Microsoft account (MSA).
After removing your personal account, click "Add account" and sign in using your preferred personal Microsoft account (MSA).
You can find a more detailed guide on this matter in the article: Manage your Microsoft Learn profile settings | Microsoft Learn.
In case you are not part of an organization that can assign you a work or school account (AAD), you can create one by signing up for a Microsoft 365 free trial, as stated in the article: Sign up for Power BI with a new Microsoft 365 trial - Power BI.
We hope that you find this information to be helpful. If you require assistance with your Learn profile, please let us know. If we do not receive a response, the case will be closed and locked after one business day.
Best regards,
