I am trying to add an email to outlook but I am getting the error invalid credentials extended error

Question

I had my email in Outlook and I changed my password last week and it was working but suddenly it stopped working. I could no longer send and receive emails. I had to remove the account and tried adding it back but I get the error 'Invalid credentials extended error' and cannot add it. How can I add my email account back?

To resolve the "Invalid credentials extended error" when trying to add your email account back to Outlook, follow these steps:

1. Clear Cached Credentials: Sometimes, Outlook may still be using old credentials. To clear them:
   • Open Control Panel and go to Credential Manager.
   • Look for any entries related to Outlook or Microsoft Office and remove them.
   • Restart Outlook and re-enter your credentials.
2. Check for Updates: Ensure that your Outlook is updated to the latest version. Sometimes, issues can arise from outdated software.
   • Go to File > Office Account > Update Options > Update Now.
3. Use the Correct Email Settings: Ensure that you are using the correct settings for your email account. If you are unsure, check with your email provider for the proper configuration settings.
4. Create a New Profile: If the issue persists, consider creating a new Outlook profile:
   • Go to Control Panel > Mail > Show Profiles > Add.
   • Follow the prompts to create a new profile and add your email account.
5. Enable Modern Authentication: If your organization uses modern authentication, ensure it is enabled. Check with your IT team if necessary.

By following these steps, you should be able to add your email account back to Outlook successfully.
