Outlook iOS – Unable to sign in to personal account after removing work account

I started experiencing this issue after adding my professional account to Outlook on my iPhone. Since Outlook mobile would not allow me to use both my personal and work accounts as expected, I removed the work account, deleted the corporate VPN/management profile from iPhone Settings, and uninstalled Company Portal.

However, Outlook still automatically detects my former work account when I open the app. I can skip it and try to sign in with my personal account, but the sign-in fails.

I receive errors such as “Network request timed out [2602]”, “Session expired” and “Unable to add account”.

How can I completely remove the remaining work account association and restore access to my personal Outlook account?

    Hi @Tarik Jamal

    Before attempting any further troubleshooting, please note that there is currently an ongoing Microsoft service disruption affecting Outlook and Exchange Online MO1550821 classifies the issue as a Service Degradation affecting Exchange Online, Microsoft Teams, SharePoint Online, Microsoft Copilot, and Microsoft Defender XDR.  

    Because backend connection timeouts and traffic imbalances may affect authentication requests during this period, local troubleshooting steps on your iPhone may not resolve sign-in issues until service stability is restored.  

    Microsoft has identified that the affected infrastructure is experiencing elevated load across multiple regions, which is likely contributing to the connectivity errors. Microsoft is currently restarting and repairing impacted portions of the infrastructure to restore capacity. Additionally, they are investigating an unexpected increase in a specific type of service traffic and evaluating options to redirect traffic to alternative infrastructure to expedite recovery.  

    Below is the latest update I've been able to monitor regarding Incident ID MO1550821 as of now:

    If you're an end user without admin permissions, kindly reach out to your Microsoft 365 administrator and ask them to monitor this incident and keep you informed of any relevant updates.

    Please kindly note that this is a user-to-user support forum and as a fellow forum user, I’m unable to directly influence or expedite the resolution, nor can I provide a confirmed timeline for when everything will return to normal. However, please rest assured that the relevant teams are working to get this resolved as quickly as possible. 

    I really appreciate your patience and understanding here. Hopefully, the issue will be fully resolved soon so that everything is back up and running smoothly for all of us.

    For this iPhone scenario, the remaining association is most likely being held outside Outlook itself. Since the work account, management profile, and Company Portal were already removed, focus on clearing any cached Microsoft sign-in state and then re-adding only the personal account.

    1. Remove the account from Outlook again
      • Open Outlook.
      • Go to Settings.
      • Select the affected account if it still appears.
      • Choose Delete Account.
    2. Restart the iPhone
      • This helps clear cached app state before signing in again.
    3. If the personal account is also present in Apple Mail, remove it there too
      • Go to Settings > Mail > Accounts.
      • Remove the Outlook account if it is listed.
      • Restart the device again.
    4. Clear Safari website data
      • Go to Settings > Safari.
      • Tap Clear History and Website Data.
      • This is important because Outlook sign-in on iPhone can reuse cached web authentication state.
    5. Add the personal account back
      • Open Outlook.
      • Add the account again and complete the Outlook.com sign-in flow.
    6. If Apple Mail is also being used for the same personal Outlook.com account
      • Add it back as Outlook.com, not as a manually configured basic-auth account.
      • In Apple Mail: Settings > Mail > Accounts > Add Account > Outlook.com.
    7. If sign-in still fails
      • First confirm the personal Microsoft account can sign in outside the app by using the Microsoft account sign-in flow or the Sign-in Helper tool.
      • If recurring password prompts started recently, update to the latest Outlook mobile app version.

    If the issue started after changing the primary alias on the Outlook.com account, delete and re-add the account in Outlook. That is a known issue.

    If Outlook continues to detect the former organization account after these steps, the remaining identity can also be retained in Microsoft Authenticator. Removing the old work account there can help, but only if that account is no longer needed for sign-in approvals.
