Can you go to your Windows Settings > Accounts > Access Work or School (note, it is the briefcase icon, not the little person icon). Then see if the organization email address is still listed? If so, click on it and then disconnect it. restart the computer after that.
How do I remove a business account from my personal computer?
I used my personal laptop (Office 365 Windows 11) while working for a company I parted ways with, and I no longer have access to their IT administrator. How do I remove the account from my computer?

2026-04-02T22:52:13.5+00:00 To remove the old work/school (business) account from a personal Windows 11 PC, remove it from Windows account settings. This only disconnects the device from that organization; it does not require access to their IT admin.
Follow these steps on the Windows 11 device:
- Open Settings from Start.
- Go to Accounts.
- For a work or school account used on the device:
- Select Access work or school (briefcase icon).
- Select the old company account.
- Choose Disconnect (or Manage → Sign out everywhere, depending on what is shown).
- If the account also appears under Email & accounts:
- In Settings → Accounts → Email & accounts, select that work account.
- Select Remove account and confirm.
After this, the device will no longer use that business account for sign-in to work resources (email, Teams, etc.) from that tenant.
If the account is still signed in to individual apps (like Teams or Office), sign out within each app:
- In Teams (desktop or web): select the profile picture at the top of the app → Sign out.
