How to Fix Outlook and Teams Sign-In Issues on iPhone After Leaving a Company
Question details
The user is unable to sign in to their personal Microsoft 365, Outlook, or Teams accounts on an iOS device after their previous company credentials and management apps were removed.
- Product
- Microsoft Outlook and Teams
- Device & OS
- iOS
- Scenario
- Attempting to switch from a corporate Microsoft account to a personal Microsoft account on a personal iPhone after leaving a job.
- Observed behavior
- The sign-in process fails continuously, even after the user has uninstalled the Microsoft apps and removed the Intune Company Portal.
Ensure you have your personal Microsoft account credentials ready and verify that you have a stable internet connection before adjusting your device's profile settings.
Remove Leftover Work Profiles and Accounts from iOS Settings
Use this solution to clear out any hidden Mobile Device Management (MDM) profiles or Exchange accounts that are forcing your iPhone to look for your old company's login server.
Even after deleting apps like Intune, iOS may retain the device management profile or work email configuration, which intercepts sign-in attempts for Microsoft apps.
Go to the Settings app on your iPhone. Tap 'General', scroll down, and select 'VPN & Device Management'. If you see a work or school profile listed, tap it and select 'Remove Profile'.
Navigate back to the main Settings menu, tap 'Mail', and then 'Accounts'. If your former company's Exchange or Outlook account is still listed, tap it and select 'Delete Account'.
Go to Settings, tap 'Safari', and select 'Clear History and Website Data'. This removes cached corporate login tokens that might be redirecting your sign-in attempts.
Restart your iPhone, download Outlook or Teams from the App Store again, and attempt to sign in using your personal Microsoft account credentials.
Isolate the Issue Using a Web Browser
Test your personal account on a web browser to determine if the issue is with the iOS apps or your Microsoft account itself.

Frequently Asked Questions
Why is my iPhone still asking for my old company login after I deleted the apps?
Your iPhone likely still has a Management Profile (MDM) installed by your former employer, or Safari has cached your old corporate login tokens. You need to remove the profile from Settings > General > VPN & Device Management and clear your Safari web data.
Will resetting my iPhone's network settings help with Microsoft Teams sign-in issues?
Yes, if the authentication server is being blocked by stale DNS records or outdated network configurations, going to Settings > General > Transfer or Reset iPhone > Reset > Reset Network Settings can resolve connection-based sign-in failures.
How do I contact my previous organization's administrator if I am locked out?
If your personal account was inadvertently tied to a corporate license or policy that you cannot remove locally, you will need to reach out to the IT helpdesk or HR department of your former employer to have them manually revoke your device from their Azure Active Directory.
Can I use my personal Microsoft account on the exact same apps my company used?
Yes. The Microsoft Outlook and Teams apps support both enterprise and personal accounts. However, if they were initially installed via a company portal, you must completely uninstall them, remove the management profile, and reinstall them directly from the App Store as a regular user.
