Unable to add a new email account to the Windows Mail app? Try These Fixes

The number of email accounts you can add to an email client is not limited. This way you can access all your emails from one place, allowing you to keep track of everything you need to do without having to switch devices.


Most of the time, adding a new email account in the Mail app is quite simple, but sometimes it doesn’t work. Throughout this guide, we’ll take a closer look at why this is happening and how to fix it.


Why can’t you add a new email account?

If you can’t add a new email account in the Windows Mail app, there are several reasons that can contribute to the problem. Here are the most common ones that could explain why you are having the problem:

  • The internet connection you are using is not stable.
  • Your Windows is outdated which causes several system components and applications to malfunction.
  • The Mail app itself is outdated. It is not uncommon to encounter issues like outdated apps due to incompatibility issues.
  • The application or the system is facing some kind of corruption error, which is preventing it from performing basic tasks.

Now that we know the potential causes of the problem, let’s take a look at the solutions that worked for other affected users. Before proceeding, we strongly recommend that you switch to the administrator user account on Windows, as some methods will require administrative access to perform.

1. Check your internet connection

The first thing we recommend you do if you’re having trouble with the Mail app is to check if you’re connected to a stable internet connection.

It is mandatory that you are connected to a strong internet connection in order to perform any action in the Mail app, including adding or deleting an account and receiving emails. Consider adding the targeted email account to Mail app on any other device if you have multiple devices (using different connection) and check if you are still facing the same issue. Our guide on fixing network connection problems on Windows has lots of information you can refer to to find a solution.

2. Install all available Windows updates

Ideally, you should keep your Windows up to date at all times. Outdated systems are an easy target for malware and other security issues.

Microsoft frequently releases system and driver updates that provide new features and bug fixes and most of the time, simply updating your system to the latest version can fix several issues.

The steps listed in this method are appropriate for Windows 11 users. If you are a Windows 10 user, follow the steps for installing updates available in this guide.

  1. Click on the windows icon in your taskbar and choose Settings from the list of available options. Alternatively, you can press the Win + I keys simultaneously on your keyboard to launch the Settings app.
  2. Picking out Windows Update from the left pane.
  3. In the right pane, click the Check for updates button.
  4. The system will now search for available updates and list those found. Install all updates one by one.
  5. Once the updates are installed, restart your PC and on restart check if you can now add a new email account in the Mail app.

If the issue still persists, proceed to the next method below.

3. Update the messaging app

If your system is up to date, the next thing to do is to ensure that the Mail app is also updated.

For this we will use the Microsoft Store app.

Here’s how to update the Mail app:

  1. Launch Microsoft Store and click on the Library icon in the lower left corner of the window.
  2. In the next window, click the Get updates button.
  3. The Store now lists apps that need to be updated and automatically starts installing their latest available updates. If the Mail app is outdated, you’ll also see it listed. Wait for the updates to install, then perform a reboot.
  4. On reboot, launch the Mail app and try adding the targeted email account again.

4. Run Windows Store Troubleshooter

The Windows Store Troubleshooter is another handy tool you can use to identify and fix issues with Windows apps.

This tool works like most troubleshooting utilities developed by Microsoft. You can access it through the Settings app. If after a scan it finds any issues in the system, it will offer you some fixes which you can also apply using the troubleshooter.

If the app update is not working, run the Windows Store troubleshooter to check if a corruption error in the app is causing the issue.

5. Repair or Reset the Mail App

Another way to fix Mail app issues is to use the built-in repair feature. This feature is designed to analyze the application for any inconsistencies and then fix the identified issues.

In most cases, repairing the app does the job. However, if the problem persists, you can try resetting the app, which will bring the app back to its default state.

We have divided this method into two parts. First, we will try to repair the application. If it does not work, we will proceed to reset it.

Follow these steps to continue:

  1. Launch the settings by pressing the Win + I keys together.
  2. Picking out apps from the left pane.
  3. Move towards Apps and features.
  4. In the next window, find the Mail and Calendar app and click on the three dots associated with it.
  5. Picking out Advanced options from the context menu.
  6. Head to the Reset section and click the Repair button.

Wait for the process to complete and then check if you can successfully add the new email account now. If you still can’t, follow these steps:

  1. In the same window, click the Reset button.
  2. Follow the on-screen instructions to continue.

Keep in mind that by resetting the app, you may lose custom settings and preferences within the app.

Re-add multiple email accounts successfully

You should be able to successfully fix the Mail app problem using the methods mentioned above. If you encounter the same problem again, you can switch to another email client until Microsoft releases an official fix for this problem.
