The Problem Explained
Every Windows 10 error has a different origin and effect on your system. Some prevent you from changing specific settings, while others can keep you from using your computer entirely.
Although the 0x80070490 Windows 10 error appears slightly more forgiving at first glance, it can be a significant problem for your PC if not resolved quickly, and here’s why.
The 0x80070490 error on Windows occurs when a user attempts to upgrade/update their operating system. It prevents them from doing so.
If you’re aware of the importance of Windows updates, you already know what this can potentially lead to.
In a time when online security needs to be taken very seriously, missing out on important security-focused Windows updates can threaten your privacy and personal safety.
To resolve the 0x80070490 Windows 10 problem, there are a few proven methods you can use. Doing this as soon as possible means restoring your ability to download critical operating system updates again without further problems.
Fix 1: Update The Windows 10 Mail & Calendar App
A Reddit user offered this solution, and multiple other Windows users confirmed that it works in the comment section.
It’s a really simple fix but, if you’ve never done it before, follow the steps below to ensure you get it right on the first try.
Here’s what you need to do:
- Open the Microsoft Store and find the Mail & Calendar App.
- Click “Update” to download the latest changes.
- Wait for the process to complete, then restart your PC.
The 0x80070490 error should now be gone.
This fix works because the bug is resolved by the latest Mail & Calendar app update, but you might not have it as it wasn’t included for everyone in the Windows Update.
This will most likely solve the problem. If it somehow doesn’t, there are also other methods you can try.
Fix 2: Run The System File Checker Tool (SFC.exe)
At first, this looks like quite an advanced fix, and it could seem intimidating for those who have never used the command prompt or anything like it.
Fortunately, you will find that this process is quite simple once you try it. Take a look at the steps below:
- Click on the Windows Search located in the bottom-left corner of your taskbar.
- Type in Command Prompt, then right-click it and select Run as Administrator.
When the command prompt launches, type in the following commands and press Enter after each one:
- DISM.exe /Online /Cleanup-image /Scanhealth
- DISM.exe /Online /Cleanup-image /Restorehealth
- sfc /scannow
The last command (sfc /scannow) will initiate a scan process which you need to let complete before closing the command prompt. There shouldn’t be any errors detected after the scan finishes.
This fix was recommended by a Microsoft Official, and numerous users have confirmed its reliability. It’s a safe way of dealing with this problem.
When done, restart your computer and see if the 0x80070490 error persists.

There’s an easy way to reset the Mail & Calendar App, and we recommend it as it has been found to be a working solution for many Windows users encountering this error.
Here’s how to do it:
- Press Windows + I on your keyboard at the same time to open the Windows Settings panel.
- Click on Apps and select Apps & Features from the left bar menu.
- Look for the Mail & Calendar app. You might have to scroll down to find it.
- Click on the app and select Advanced Options.
- Scroll down until you see the Reset button, then click it.
The app will now reset, and you can re-launch it afterward. You don’t have to restart your PC after performing this fix. The problem should no longer occur.
You now know how to fix this notorious Windows problem, which prevents users from downloading Windows updates and using certain apps and features.
Remember to always download the most recent official updates published by Microsoft for all Windows apps, as this keeps your PC protected against the latest bugs and exploits.
