Having problems adding accounts with Outlook 2024

Question

On my new computer running Outlook 2024 will not let me add imap accounts. Comes back with error msg stating either password wrong or server not responding. This is for servers that host my personal account.

BTW, on my old computer with Outlook 2024, all my account work and load into one inbox.

What am I doing wrong?

Thanks for any help or ideas.

Answer 1

It seems that you are experiencing issues adding IMAP accounts in Outlook 2024 on your new computer. Here are a few suggestions that might help you resolve the problem:

1. Check Account Settings: Ensure that you are entering the correct email address and password. Double-check the server settings for your IMAP account, including the incoming and outgoing server names, ports, and encryption methods (SSL/TLS).
2. Firewall/Antivirus Settings: Sometimes, firewall or antivirus software can block Outlook from connecting to the email server. Temporarily disable these to see if it resolves the issue.
3. Internet Connection: Make sure that your internet connection is stable and that you can access other websites or services without issues.
4. Windows Credentials: If you have previously saved credentials for your email account, they might be causing conflicts. You can manage your Windows Credentials in the Control Panel and remove any outdated entries related to your email account.
5. Repair Outlook: You can try repairing your Outlook installation. Go to Control Panel > Programs > Programs and Features, select Microsoft Office, and then choose the Repair option.
6. Reinstall Outlook: If none of the above solutions work, consider uninstalling and then reinstalling Outlook 2024.

If you continue to face issues, it may be helpful to consult with your email provider for specific settings or troubleshooting steps related to their service.
