I ran into a scenario where knowing the Outlook Profile configuration
was useful, ensuring the customer did not have a POP3 configuration for
their account in addition to their Exchange account (there by
generating duplicate emails).

After some research I found that it is possible to review a section of
the customer's registry for all the stored profile information.

The location in the registry on the customer's machine:
HKEY_CURRENT_USER\Software\Microsoft\Windows NT\CurrentVersion\Windows
Messaging Subsystem\Profiles

When accessing this section remotely it will be in the form/path
similar to:
"HKEY_USERS\S-1-5-21-945540591-4024260831-3861152641-40215\Software\Microsoft\Windows
NT\CurrentVersion\Windows Messaging Subsystem\Profiles" ,each friendly
named profile will have a listing here.

Once you have expanded the respective profile there will be a subkey of
"9375CFF0413111d3B88A00104B2A6676" , this is where the individual
accounts/services have their configuration information stored. Once you
are at the top of this tree, it is best to do a search on the term
"POP3 Server". Double-click on the entry to view the Value Data, the
Server name will be listed in plain English to the right of the hex
data.
