How do I remove the list under “Choose an account” in the top-right corner of the Edge browser on macOS?

I logged into my email account in Outlook on my MacBook, and then signed out. However, the sign-in prompt still appears in the top-right corner of Edge, and when I click “Sign in to Sync,” it logs me in immediately without any issues. This is very insecure. I’ve tried various methods to remove it, but every attempt has failed.

To resolve this, I tried the following methods:

1. I first checked to see if there were any relevant accounts in my Mac’s Password & Security settings and Internet Accounts under System Settings, but after checking, I didn’t see “******@outlook.co” in the top-right corner.

2. I opened “Keychain Access” on macOS to check for any entries related to “******@outlook.com.” I found “com.microsoft.oneauth.XXXXX” and deleted it. However, when I reopened Edge, not only did the list in the top-right corner remain, but a new “com.microsoft.oneauth.XXXXX” entry had also regenerated in Keychain Access.

3. I tried completely uninstalling Edge, including the configuration files in the Library, using AppCleaner. I also used the command

grep -r “******@outlook.com” ~/Library 2>/dev/null

to scan for any remaining files and delete them one by one. After that, I restarted my computer, but when I opened Edge, the message “Choose An Account ******@outlook.com Sign in to Sync” still appeared in the top-right corner.

4. I completely uninstalled Edge again and used the “Microsoft_Office_License_Removal_2.7.pkg” tool you provided. I also deleted the relevant entries in Keychain Access and restarted my computer. However, when I opened Edge, the entry in the top-right corner was still there.

5. I logged into my account and selected “Sign out of all devices.” Now, I can only say that I won’t log back in, but the list is still there, which is still a security risk.

The only way I can get rid of this list right now is to reinstall my operating system or create a new user account, but that’s a solution I simply can’t accept. Can anyone help me? How can I resolve this issue?
