My classic Outlook will not create a new pop account

Question

I am using classic Outlook for a POP account. For no reason that I am aware of it stopped access to my POP account. I deleted the account thinking that I could just add it back, now I cannot add the account. Yes, I have entered all server settings manually.

Answer 1

Hello Aaron Carlson,

Welcome to the Microsoft Q&A forum.

From the description, it’s understandable why this is frustrating, especially since the POP account previously worked and now cannot be added back in classic Outlook.

There is already a Q&A Assist response in this thread, and the guidance provided there is accurate for classic Outlook on Windows. If you haven’t had a chance yet, please try the steps outlined in that answer first, particularly the parts around manual account setup, app passwords, and creating a new Outlook profile.

To add some additional context that may help:

When a POP account suddenly stops working and cannot be re‑added, the cause is often outside of Outlook itself. Many email providers restrict or disable POP access after security changes, password updates, or enforcement of two‑step verification. In these cases, even if the server settings are entered correctly, Outlook will not be able to create the account unless the provider explicitly allows POP sign‑ins.

It’s also important to note that contributors on this forum do not have visibility into mailbox credentials, provider authentication status, or backend account permissions. If Outlook continues to reject the POP account after following the Q&A Assist steps, it’s recommended to confirm directly with the email provider whether POP is still supported for that mailbox and whether an app password is required.

If POP access is no longer permitted by the provider, adding the account using IMAP is typically the supported alternative, as it uses a different authentication and synchronization model.

If you’ve already tried the Q&A Assist steps, feel free to share which part did not work as expected, and more targeted guidance can be added based on that.

I hope this helps clarify the situation and next steps.

Answer 2

For classic Outlook POP accounts that suddenly stop working and then can’t be re‑added, focus on three areas: app passwords, manual setup, and known POP issues.

1. Confirm whether an app password is required Many non‑Microsoft providers (Gmail, Yahoo, iCloud, some ISPs) now require an app password instead of the normal account password when using classic Outlook.

• If the provider uses two‑factor authentication or has “less secure apps” disabled, generate an app password on the provider’s website.
• Use that app password in Outlook instead of the normal mailbox password.
• For general guidance, see the “You might need an app-password” and “App password message” sections, which explain that IMAP/POP accounts in new and classic Outlook may fail setup unless an app password is used.

2. Use classic Outlook’s manual/advanced setup correctly Since the account was deleted and re‑added manually, verify the full advanced setup path:
3. In classic Outlook, select File > Add Account.
4. Enter the email address, select Advanced options, and check Let me set up my account manually, then select Connect.
5. Choose POP.
6. On Account settings, confirm the incoming and outgoing server names, ports, and encryption exactly match the provider’s POP settings. If unsure, use the provider’s documentation or the POP and IMAP account settings reference.
7. Select Next, then enter the correct password (or app password) and select Connect.

If automatic detection fails, use the troubleshooting guidance to choose Change Account Settings and correct the server names, ports, and encryption, then try Connect again.

3. Check for the current POP bug on Windows 11 If the machine is on Windows 11 and using POP, be aware of a known bug where classic Outlook POP profiles hang, freeze, or fail to behave correctly after a specific Windows update (KB5074109). Symptoms include Outlook freezing, not saving changes, and general POP instability across multiple machines.

• If this matches the behavior (especially if the issue started right after a Windows update), the temporary fix is to uninstall the January 2026 Windows 11 update KB5074109, as described in the referenced thread.
• If the update cannot be removed through normal means, follow the alternative approaches in that thread.

4. If classic Outlook still won’t add the POP account If all of the above are correct (app password, POP settings, no blocking Windows update) and the account still cannot be added:

• Try creating a new Outlook profile via Control Panel > Mail > Show Profiles… > Add…, then add the POP account in that fresh profile using the steps above.
• If the provider supports IMAP and POP is not strictly required, consider adding the account as IMAP instead, using the provider’s IMAP settings and an app password if required.
