Are you getting the error code 0x8007042b when trying to add Google accounts on Microsoft’s Mail app? Don’t worry because we have solutions that you can try.

Fix #1: Make sure your Google account is connected to your PC

Sometimes, the error only shows because you have failed to connect your Google account to your Windows PC. To resolve the problem, here’s what you should do:

1. Sign in to your Google account.
2. Go to the Security section.
3. Click on the Connected apps and sites option to open it.
4. Select the Connected Apps option.
5. Check if your Windows PC is included in the list. If not, add it.

Fix #2: Enable IMAP on Your Google Account

Assuming you’ve already connected your Google account to your PC, you now need to create a new IMAP account. But for you to do that, you have to enable IMAP on your Google account first.

Follow these instructions on how to do it:

1. Sign in to your Gmail account.
2. Click the tiny gear icon in the upper-right corner of your window.
3. Choose Settings.
4. Select Forwarding and POP/IMAP.
5. Click Enable IMAP.
6. Hit the Save Changes button.

Fix #3: Create an IMAP account

Now that you have enabled IMAP on your Google account, it’s time to create a new IMAP account in the Mail app. After this, everything should be fine.

To create an IMAP account, here’s what you should do:

1. Launch the Mail app.
2. Navigate to Settings > Accounts > Add Account > Advanced Setup.
3. Click Internet Email.
4. Fill in the following details:
   • Account Name: {any string like “My Account”}
   • Your Name: {your name like “Joy Bloggs”}
   • Incoming Mail Server: imap.Gmail.com:993
   • Account Type: IMAP4
   • User name: {your Gmail address}
   • Password: {the one-time password you just generated, otherwise just your Gmail password}
   • Outgoing SMTP email server: smtp.gmail.com:465
   • All checkboxes checked
5. Try to connect your Gmail account with your newly created IMAP account.

Fix #4: Delete system junk and unnecessary files

There are instances when system junk and unnecessary files accumulate on your Windows computer and mess with important processes. So, it is important to make it a habit to delete these files on a regular basis.

To get rid of junk and other unnecessary files, go through all your system folders and delete the files you no longer need. It is worth noting, though, that doing this manually is quite risky. If you delete an important system file, your computer might end up completely dysfunctional.

Your best option is to use a trusted third-party PC repair tool like Outbyte PC Repair. In just a few clicks, unneeded and temporary files can be swept out, reclaiming gigabytes of free space on your hard disk.

Fix #5: Disable the Credential Manager Service

Some users have tried disabling the Credential Manager Service to fix the problem. Here’s how to do it:

1. Access your user folder. You can find it under the C drive.
2. Choose Users and right-click on your PC name.
3. Select Properties.
4. Navigate to the Security tab and click Advanced.
5. Choose Owner and click Change.
6. Go to Add > Entity > Advanced > Search.
7. Now, navigate to All Application Packages > Accept.
8. Click Full Control and hit Apply.
9. If error messages appear while applying permissions, just ignore them.
10. Next, go to Start and input services into the search bar.
11. Right-click on the first item on the list and select Services as Administrator.
12. Find Credential Manager Service and right-click on it. Click Stop.
13. Restart your computer.
14. Go back to Services and click Credential Manager Service.
15. Start it and set it to Automatic.
16. Restart your computer.

Fix #6: Use a restore point

Did the error appear after installing a program on your Windows computer? If that is the case, try reverting your PC’s settings to a time when everything worked fine.

Sure, you can always try uninstalling the suspicious app first. However, using a restore point is a better option as it allows you to undo all the recent changes you have applied on your PC, including the installation of the suspicious app.

To revert your PC’s settings to a certain restore point, follow these steps:

1. Go to Start.
2. Into the search bar, input control panel and hit Enter.
3. Click Backup and Restore.
