Windows 10: Mail and Calendar app won't launch

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 *Smile

I can't launch the mail/calendar app

I haven't been able to launch the mail app since I cancelled sign in by shutting down my pc. this is probably a glitch like the disable start menu glitch I found yesterday. also, because the calendar is practically the same app (they update together, they
are in settings together, they do everything together (like twins!) s now I can't launch mail or calendar and outlook 2013 won't send or receive emails. I've slowly glitched my way into a corner. I'm stuck. please help!

 

Mail and Calendar app won't launch

My Hotmail Account is active.

The fixes listed DO NOT work.

-Using Powershell (Run as Administrator) and uninstalling, then going to the Microsoft Store and reinstalling

-Using the Windows App store Troubleshooter

No matter how many times I uninstall and reinstall "Mail and Calendar" - It JUST will NOT launch.

 

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 Start menu, type Windows PowerShell in the search bar.


2.Right click on the Windows PowerShell and 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.... *Sad

 

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 said product installed!
Restarted - still said product installed.
Went to windows store online as 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.
