I have Windows 10 Ver 1607 (OS Build 14393.187)
After uninstalling Microsoft Office 2016 I am unable to use the Windows 10 Mail and Calendar app. When I try to open either Mail or Calendar they crash immediately. I have tried every conceivable method that has been posted on this forum. I've done sfc/ scannow & DISM. I've tried removing with the Powershell command and then reinstalling from the store. AND I've also done an in place upgrade of Windows 10 and still no luck. Also tried switching to a Local Account and nothing works.
I've used all the available Windows troubleshooters and I really thought that the in place upgrade would have solved the problem but alas it has not.
Can someone please help? I'm pulling my hair out trying to figure out a solution to this.
Thanks in advance!
Post Script: I just checked my Event Viewer and noticed these 2 error messages for Mail & Calendar:
1) Activation of app microsoft.windowscommunicationsapps_8wekyb3d8bbwe!microsoft.windowslive.mail failed with error: Access is denied. See the Microsoft-Windows-TWinUI/Operational log for additional information.
2) Activation of app microsoft.windowscommunicationsapps_8wekyb3d8bbwe!microsoft.windowslive.calendar failed with error: Access is denied. See the Microsoft-Windows-TWinUI/Operational log for additional information.
Hi, very helpful clear post- thanks. This may help:

Why won't an in-place upgrade repair install fix everything?
Simple. It doesn't replace absolutely everything. It can't, 'cos it keeps (in general but not completely) user programs and settings.
Thus it is possible that something which has an adverse effect on system functions is retained- copied back into the clean Windows.
Hi Dalchina,
I had a look at that Windows thread and the only thing on there I didn't try is taking ownership of the Windows Apps folder, renaming it to "oldWindowsApps" then doing an in place upgrade again. At the moment I'm running a tool from Tweaking.com Windows repair. It's helped me in the past with several issues that I was unable to fix on my own. So after this tool runs and is still unable to fix it I'm going to try doing the renaming thing and doing another in place upgrade again. What a nightmare. I don't even really use those apps but it annoys me to no end that they don't work properly.
Also, before I do the in place upgrade again I was wondering if I should remove Malwarebytes?
Did you notice this odd para?
After the process do the following.I checked for and installed Windows Updates.
I had to right click on my clock (bottom right of Desktop) and change it to the correct time zone.
I also had to open my Mail App and for each email account I opened SETTINGS then OPTIONS and CHECKED the BANNERS and SOUNDS boxes (they were unchecked).
Now my EMAIL notifications are working perfectly.
- can't say I understand it,but it struck me as the kind of odd thing that might help, given the error messages matched yours exactly. No guarantees of course. Have a careful look.The key is to research your error message.
Ok, I've found the solution thanks to the Microsoft thread link that you provided Dalchina! What worked for me was to "take ownership" of the Windows Apps folder, renaming it to "oldWindowsApps" and then doing an in place upgrade. Now both my Mail & Calendar apps are working again.
Great- personally I wouldn't rely on MS for an email solution- I was happy with Outlook Express, then had to transfer to Win Mail when they introduced that, then they took that away and didn't provide an email client at all... so I use Thunderbird. Easy to back up data, and move it to a new PC.
Now you have everything working, hopefully, if you don't already, this is what we strongly recommend:
Creating disk images lets you restore Windows and all your disks and partitions to a previous working state, quickly and probably without technical help.
You can recover from:
- a failed disk drive (restore to a new one)
- ransomware (which encrypts your disk)
- user error
- unrecoverable problems from failed updates to problem programs
- unbootable PC (hardware faults aside)
Images also act as a full backup- you can extract files too.
You can even use images to help you move more easily and quickly to a new PC.
Imaging can even help you sleep at night knowing you have a second chance.
Many here recommend Macrium Reflect (free) as a good robust solution and more reliable than some others. It’s
- more feature rich
- more flexible
- more reliable
than Windows Backup and Restore system images.
It's well supported with videos, help and a responsive forum.
I have used Macrium in the past and have made backups but It's been a long time since I did a backup. I got lazy and relied on system restore which is not always reliable. Thank you for the reminder. I'm going to install it now on both my systems and do backups on a more regular basis.
