Hi Justin,
Thank you for reaching out and welcome to Microsoft Q&A!
I understand you’re seeing an organization/educational account suggested every time you try to sign in, and the “Forget” option doesn’t seem to work properly. Since clearing the cache works but only temporarily, this suggests the account information is stored outside of browser cookies (e.g., in your Windows or Edge profile, or via single sign-on in a domain environment).
Please try the steps below:
1. Confirm if your device is joined to a domain network
If your computer is part of your organization’s domain, single sign-on can automatically add your work/school account back to the sign-in page. In this case, you may need to disconnect the account from your Windows profile or adjust your work/school account settings.
2. Test signing in with your personal account directly
Use the link below to open a sign-in prompt that allows you to select the account manually. Sign in here with your personal Microsoft account: Sign in to your account
3. Remove the work/school account from your Windows profile
- Open Windows Settings > Accounts > Access work or school.
- Select your work/school account > Disconnect.
- Also check Settings > Accounts > Email & accounts, and remove it from Accounts used by other apps.
4. Clear saved site data only for Microsoft login sites
In Edge:
- Go to Settings > Cookies and site permissions > Manage and delete cookies > See all cookies and site data.
- Remove entries for login.microsoftonline.com, microsoftonline.com, login.live.com, live.com, and outlook.com.
5. Try an InPrivate window to verify
Open Edge in InPrivate mode (Ctrl+Shift+N) and check if your personal account is now the only one suggested.
I truly hope this helps! Please let me know how it goes! Take care.
Warm regards,
Winnie
