Hi,

I have a weird issue. My mail and calendar app will not launch.

This started happening on Friday 7 August 2015 after the first cumulative update. I am on Windows 10 Home 64 bit. I have a Sony Vaio laptop and my installation is an upgrade from Windows 7 Home.

Out of all my apps it's only these 2. I click on the icon and nothing happens. It won't load and then fail, it just doesn't do anything. Another weird behavior I am noticing is that when I right click the icon for Mail or Calendar (it happens on both) the option to "pin to taskbar" has gone. Pin to start is there. This is the only app this happens on.

The other thing which is happening if in the Event Viewer under "Applications and Services Log/Microsoft/Windows/Apps/Microsoft-Windows-TWinUI/Operational" where app launching is logged.....instead of it saying:

The app microsoft.windowscommunicationsapps_8wekyb3d8bbwe!microsoft.windowslive.mail was activated for the Windows.Launch contract successfully.

it says:

The app Microsoft.Windows.Cortana_cw5n1h2txyewy!CortanaUI was activated for the Windows.Launch contract successfully.

I have tried WSRESET, and also "Get-AppxPackage *communi* | Remove-AppXPackage" reboot, and then reinstall Mail and Calendar app.

Any help would be so appreciated

ok this works. There must have been an update as the install file has changed from under 179 mb to 180 mb:


1.Open the Startmenu, type Windows PowerShellin the search bar.


2.Right click on the Windows PowerShelland select Run as administrator.


3.Enter the below command to reinstall the Mail and calendar app.


get-appxpackage *microsoft.windowscommunicationsapps* | remove-appxpackage


After performing the above steps, install the Mail and calendar app form the Windows store.

I am having the same problem as the OP.
I did the reinstall of the app, then launched the mail app again, got to "get started" with my accounts, the app opens and then crashes again....

THANKS man. For me both mail and calendar were bust, they would open for about 3 second then crash.

I followed your powershell command, but it still saidproduct installed!
Restarted - still saidproduct installed.
Went to windows store onlineas opposed to the store app - and is said "FREE"
Clicked FREE and it downloaded.
Now both mail and calendar have opened and seem fully functional.

One other thing, prior to all of this I had switched my windows user account to a local account (and restarted) in user settings.
