Hello,
Thank you for posting in Microsoft Community forum.
Based on the description, I understand your question is related to delete account.
If you have used your Outlook account to sign in to Windows and have enabled BitLocker encryption, you will need the recovery key to access your data. If you do not have the recovery key, you may not be able to access your data.
You can try removing the deleted email account from the Windows settings in second PC by Settings > Accounts > Email & accounts, select the email account you want to remove, and click on the "Remove" button. If the "Remove" button is grayed out, you may need to add a new account first and then remove the old one.
Have a nice day.
Best Regards,
Molly
