Hello Bill,

Thank you for posting your query on Microsoft Community.

As per the issue description you are unable to open mail app on your laptop. However, you may try the steps mentioned in the article provided below except troubleshooter. Try to run the troubleshooter from here.

Troubleshoot problems with an app

If issue persists then there might be a chance that the Mail, Calendar, and People apps may be broken due to a licensing issue with the Store. To get these apps working again, you need to follow these steps:

• Open powershell as administrator
• Run the command Get-appxprovisionedpackage –online | where-object {$_.packagename –like “*windowscommunicationsapps*”} | remove-appxprovisionedpackage –online
• Re-install Mail, People and Calendar from the Store (green tile)

Hope the information provided is helpful. Do let us know if you have any queries related to Windows, we will be happy to assist you.

Dear Ramesh, 

I run the command you provided in powershell as Admin, but it does not help. I still have the same problem with mail!

I solved the problem with mail and calendar.

Solution: Clean install of Win10 from usb flash drive

Everything works.

Regards.

1. You can remove applications with crashes for all users (if you want!) [PowerShell]

• Get-AppXPackage -AllUsers "*People*" | Remove-AppxPackage
• Get-AppXPackage -AllUsers "*windowscommunicationsapps*" | Remove-AppxPackage
• may be errors by system rules (no errors in clean boot), but you can ignore those --> reboot PC

2.  You can remove and block this update [Any Shell]

• wusa /uninstall /kb:3081436
• download this to block an update (blocking after uninstalling)

3. And of course, you can ignore that, because "After clean install windows 10 and update (I used a few tricks order updates in the hope that something will change) these errors will occur";

re-installing Mail, People and Calendar from the Store is not variant: no crash for Mail and Calendar, but will error of access 0x80c8043e (People will still be completed after the launch)

[RESOLVE] Today I tested this: do clean install windows 10 with local account.

On the next step, update install all microsoft updates,  then sign in to your microsoft account from the Windows Store. Update all applications and YOU WILL HAVE NO PROBLEMS WITH THESE ERRORS AND CRASHING.

Good luck! (This is the best solution for me) Remeber: dont login during installation windows and before updating!

Microsoft, reconfigure your f****** cumulative update or release new, ty! I love Windows 10 too.

i have the same problem.

In order to get Email and Calendar app work again you need to create a new local user account in your Windows 10. After you do that -> Transfer all your data and files to the new created account (apps will be set to default in the start menu but software and games installed in the old account will remain installed in the new account). After you done transfering all your data and files delete your old account and set the new one as Adminstrator and connect it online to your Microsoft account in settings->Accounts. Email and Calendar apps will work again in the new windows 10 account.
