Follow the writing below ==> Answer by Sharief K == > worked for me
Open Powershell as administrator:
Right-click the Start button.
Select Command Prompt (Admin) from the menu.
When the Command Prompt window opens, type powershell and then press Enter.
The window will stay the same, but the prompt will begin with “PS”.
2.To remove the non-working Mail, Calendar, and People apps, paste the following command into the Command Prompt and then press Enter:
Get-appxprovisionedpackage –online | where-object {$_.packagename –like “*windowscommunicationsapps*”} | remove-appxprovisionedpackage –online
Wait until you receive the response confirming the operation has been completed.
3.Restart Windows.
4.When Windows restarts, click the Start Button and look in the All Apps section for the green tile with the title Store, and launch it.
Do not use the grey tile with the title Store (Beta) for this.
5.If you do not sign in to Windows with a Microsoft Account, you may need to sign in to the Store with one at this point. If you do not have a Microsoft Account, you will need to create one.
6.In the Store, search for Mail. You should find a result for Mail, Calendar, and People. Select that search result and install the app. This will take a few minutes – wait for the confirmation message saying the app is installed. You may be prompted to add a payment method. This is not required, and you can dismiss the pop-up prompt if you want.
7.The Mail, Calendar, and People apps should now be installed and visible in your Start menu with their tiles pinned.
Note that if you have multiple user accounts on your PC, you may find that the Mail, Calendar, and People apps won’t start when you are logged in with the other accounts. After doing all of these steps with one account, you will need to sign in and do steps 6 through 8 with each account to fix the apps.
