Solution 1: Check Your Yahoo Account and Send a Test Message

When Yahoo Mail is facing an issue such as IMAP & POP issue, you must check your account by composing a mail. With this method, you can try to ensure whether your mail is working or not.

3. When you find that the settings are correct, delete your Yahoo account from the app. 

4. Now, check your account by sending or receiving emails to confirm if the error has been resolved. 

Solution 3: Use an App Password or Check for an Extra Mail Address

Here, you can fix the problem by creating a new password for the app in place of the regular password. After that, you can try composing an email to ensure that the issue has been solved. 

1. In the first step, log in to your Yahoo account and head to the Account Security webpage.

Solution 4: Check Your Device’s Settings and Connected Devices

In this solution method, you should check your device’s settings on which you’re signing into your mail. Also, check for the connected devices using the steps mentioned below. 

1. To begin, launch the email settings on your device and choose the Yahoo account. 

2. Then, confirm that the Sync setting is ON and set it to a specific time.

Solution 5: Update the App or Grant Temporary Access

Sometimes, the reason for your email’s inability is that it’s not updated. Hence, updating it can boost its functionality. Also, temporary access to the app on the device must be granted. Let’s look at the steps involved in updating the Yahoo email app. 

1. To start, you should know whether your app needs an update. You should visit the app store and try updating it. 

2. If you get errors such as “server password has changed” or “authentication failed,” you can grant temporary access to the app to access the device. 

3. Now, sign in to your account and head to the Account Security settings. 

4. Next, click on the “Manage app passwords” and pick your app. 

5. After that, create a new password and use that to log in to the app. If you created a new account earlier, you should use that. 

6. If the issue isn’t resolved, you must contact the app manufacturer to resolve the error in a better way. 

Solution 6: Check for Software Blocking Ports or Use a Different App

As you know, antivirus software, firewalls, and network protocols can block ports; you should check for it. Also, use a different app. 

1. Check for software-blocking ports: Contact your Internet Service Provider or the security manufacturer and find out which software is blocking ports. 

2. Use a different app: When you know that your account is not linked to the app and you’ve tried other solutions, your app has something wrong. The app manufacturer can do something to resolve this error. Otherwise, you can also use a different third-party email app.
