FIX: Mail, People, Calendar Apps Don’t Work in Windows 10

3 quick steps to fix Mail and Calendar issues

1. Use PowerShell
2. Reinstall the apps
3. Reset Mail and Calendar
4. Run the Windows Store App troubleshooter

Many apps are not fully optimized for the Windows 10 Technical Preview builds, yet. This also applies to Microsoft’s in-house apps like Mail, Calendar or People.

Problem with Mail, Calendar and People apps is a well-known issue and Microsoft is aware of it. But until Microsoft fixes all the bugs, we have an alternative solution for this problem.

Solutions to fix Mail and Calendar not working

Solution 1: Use PowerShell

You’ll need to do a couple of things in the Command Prompt, just follow these instructions:

1. Go to Search, type cmd and open Command Prompt (As Administrator)
2. When the Command Prompt window opens type powershell and press Enter (You’ll notice that the window will stay the same, but the command line will begin with “PS”)
3. To remove the non-working Mail, Calendar, and People apps, paste the following command line and press Enter: Get-appxprovisionedpackage –online | where-object {$_.packagename –like “*windowscommunicationsapps*”} | remove-appxprovisionedpackage –online
4. Wait until you receive a confirming message that the operation has been completed and restart your computer.

Solution 2: Reinstall the apps

When your computer restarts, do the following:

1. Go to Start Menu and open the green tile of the Store App in All Apps section (Don’t open Windows Store with the grey tile, because it’s a beta version and it probably won’t help you)
2. Sign in to Windows Store with your Microsoft Account
3. In the Store, search for Mail. You should find a result for Mail, Calendar and People apps
4. Select the search result and install the apps
5. Wait for the confirmation message and you’re done (You may be prompted to add a payment account during the installation, but this isn’t necessary, so you can skip that part)
