When I right click on it from the apps list (whatever replaced the start menu), I don't get an option to open file location, or even pin it anywhere.
It doesn't seem to be in C:\Program Files\Windows Mail either.
I went to the task manager to see where the running process came from. It comes from C:\Program Files\WindowsApps\microsoft.windowscommunicationsapps_16.4.4206.722_x64__8wekyb3d8bbwe
I changed the owner of C:\Program Files\WindowsApps\ to myself so that I could access it. The only exe that I see in the folders won't run.
Even if I find the exe, will the folder C:\Program Files\WindowsApps\microsoft.windowscommunicationsapps_16.4.4206.722_x64__8wekyb3d8bbwe change its name ever?
