Outlook auto-complete backup; NK2 and .dat etc.

Level 1

I am trying to add a location to be backed up in a special profile.

I really dont care if I can enter this particular path. I just want to backup the data in the location without creating a special profile for each user individually. But here is what I tried below:

The location is: %localappdata%\Microsoft\Outlook\RoamCache and/or %localappdata%\Microsoft\Outlook\

I get a message that location is not valid when I try to use %USERPROFILE% or %localappdata%.

Excerpt snipped from below:

Outlook 2010 and 2013 does not use the NK2 file; it stores the autocomplete cache in the mailbox or data file and caches the addresses in an autocomplete stream at C:\Users\username\AppData\Local\Microsoft\Outlook\RoamCache. You can type or paste %localappdata%\Microsoft\Outlook\RoamCache in the address bar of Windows Explorer then press Enter to open the folder location where the cache is stored in a file named Stream_Autocomplete_0_[long GUID].dat.
