Yahoo! Mail is known for being cross-platform compatible. Yahoo gives POP and IMAP settings to both free and paying users to make webmail function on different devices. Both the Yahoo IMAP and POP protocols allow you to connect your Yahoo mail account to third-party email clients such as Outlook, Gmail, Thunderbird, and others that support the protocols.

Because Yahoo is widely used on platforms such as Yahoo mail on Outlook or Thunderbird, users frequently seek solutions to issues that happen unexpectedly during their use. There are numerous forums and help websites that claim to have Yahoo issue answers. This commonly happens when there is a problem with Yahoo! Mail’s POP and IMAP configuration.

An error with POP and IMAP settings for Yahoo! Mail can be caused by a variety of factors, but the problem can be resolved by following a few steps. We created a guide with all possible solutions to Yahoo POP and IMAP server issues to assist our users.

Solutions to fix “Yahoo SMTP Server Not Working” Issue

SMTP stands for Simple Mail Transfer Protocol and is a protocol for sending and receiving e – mails. If the SMTP server is down, you may have trouble sending or receiving emails. If your Yahoo Mail account’s SMTP server is down, try the following fixes:

1. Check to see whether Yahoo Mail is having any problems.

Firstly, use the procedures below to see if Yahoo Mail is experiencing any troubles before combining it with a third-party email service:

• To begin, log in to your Yahoo account.
• Send a Yahoo email to your email address using the Compose option.
• Check to see if you get the email within 5 minutes of it being sent.
• If a delivery error occurs, you will be obliged to correct it immediately.

2. Examine your IMAP and POP settings.

You must enter IMAP, POP, and SMTP settings when configuring Yahoo Mail on a third-party email client, and if Yahoo’s IMAP or POP settings aren’t working, you may have problems with the SMTP server as well. Even if you’ve entered all of the right information, your hard drive data could be corrupted, which is why Yahoo isn’t working with Outlook on iPhone.

So, for Yahoo mail, these are the correct IMAP and POP settings:

Yahoo Mail POP Settings.

Server for incoming mail (POP3)

• mail.yahoo.com is the server.

• SSL is required: Yes
• Yes, authentication is required.

3. Examine the ports to see if any software is blocking them.

Another reason the Yahoo outbound SMTP server isn’t working is because the software you’ve installed is blocking ports. Antivirus software, firewalls, and network protocols can all block ports, causing Yahoo Mail settings to fail. If possible, temporarily disable the software or contact your internet service provider for instructions on how to unblock the ports.

4. In Safe Mode, Open Yahoo.

If you’re having trouble utilising Yahoo email on the Windows Mail programme because of Yahoo IMAP settings issues, you can just boot up Windows in safe mode and use the Mail app without any add-ons. You can also run your Yahoo mail account in safe mode on the Mail app to see if there are any improvements. If your Yahoo mail settings work correctly in safe mode, the problem isn’t with your device’s default settings or fundamental device drivers.

Follow these instructions to start Windows 10 in safe mode:

• To begin, hold down the Windows+R key.
• In the Open box, type “msconfig” and then click OK.
• Select the “Boot” tab from the drop-down menu.
• Select the “Safe boot” checkbox from the “Boot settings” menu.

5. Restart your computer.

After you’ve completed the reconfiguration, you should restart your device. To fix the Yahoo mail settings issues, follow this procedure to clear out the junk and unneeded files from your system and optimise the efficiency of your device. This will be a good way to get rid of the problems you’re having with Yahoo and Outlook or other third-party programmes.

If the instructions above don’t work for you, here’s something else to try:

Using an outdated POP or IMAP account might also cause this problem, so check sure all of your information is up to date before attempting to send emails from your account.
If you have activated two-step verification for your Yahoo account, you will need to generate and use an app password for a third-party email programme. You can create a password in your Yahoo Mail account’s ‘Account Security’ section as follows:

• Go to the Account Security page on Yahoo.
• Select ‘Account Security’ from the drop-down menu.
• You’ll find the option towards the bottom.
