Does anyone know of where Windows 8 Mail app store inbox data? I'm trying to find a way if it is possible to import my Outlook 2010's PSTs (or EMLs) into this folder location. I tried looking into my user account's appdata folder but couldn't find anything useful.

Any thoughts?

I highly suspect that just dumping your PST or EML into that folder isn't going to work. Search for an export/import option instead. – Nifle Sep 2 '12 at 18:46
There's no export/import option for this app. I don't plan to dump PST or EML files into this location, but just want to see what kind of files it contains and if some secondary app could be written to add PST/EML backup to this location. – Zishan Sep 2 '12 at 22:18
@Zishan I am not convinced W8 mail stores anything locally, its a mail reader, Install Windows Live Mail if you want to POP and store email locally. – Moab Sep 3 '12 at 1:52
@Jagd yes there is, it is part of Live Essentials… – Moab Sep 26 '12 at 14:41

This seems to be what you're after, it's for Outlook 2003 but mentions PST files so fingers crossed:

You need to go to Control Panel /mail **bit/Double click and if your Outlook is configured you will see your profile. Double clic the profile and add the data file (pst) (Browse to folder that you copied it).

If you did not create a new Outlook account, open Outlook then close it without creating account. Go to controll panel / find mail ** bit, double clic, create a profile and browse for your data file that you copied to another drive.

I did a search for files looking like 'mail' changed today and found the location at

C:\Users\[machine name]\AppData\Local\Packages\microsoft.windowscommunicationsapps_8wekyb3d8bbwe\LocalState\Indexed\LiveComm\a0ba5af4dd39597b\120712-0049\Mail\7e\

I suggest having a look... somewhere down that tree. Files are .eml and they open in Outlook.
