Hi @Colleen Medved
Welcome to our forum!
Based on my research, you have to remove the accounts that don't trigger the error first, and then delete the primary account.
In addition, you may consider creating a new profile and add your current email to it, and then delete your previous profile included company accounts. More information:
- Create an Outlook profile - Microsoft Support
- Add an email account to Outlook for Windows - Microsoft Support
Hope it helps!
