Display memory used by a given process

From Task Manager I see that a process whose name is "OUTLOOK" uses 83,33 MB of memory.

I issued the following command:

Get-Process -name "OUTLOOK" |select ProcessName, Path, VirtualMemorySize, PrivateMemorySize, NonpagedSystemMemorySize, PagedMemorySize, PeakPagedMemorySize

and the result is:

ProcessName              : OUTLOOK
Path                     : C:\Program Files (x86)\Microsoft Office\Office16\OUTLOOK.EXE
VirtualMemorySize        : 1085014016
PrivateMemorySize        : 152788992
NonpagedSystemMemorySize : 117008
PagedMemorySize          : 152788992
PeakPagedMemorySize      : 224669696

Non of the date reported is at least similar to the value reported by task manager.

Which value should I select to get the same value reported by Task Manager?

Regards
