Outlook 2013 VBA: Can you Set Search Scope to "All Mailboxes"?

I need to create an Outlook search macro that will search across all mailboxes.  I have found a list of valid search scopes for Outlook 2013 (see below).  A constant for All Mailboxes is not included.  Is it possible to set a VBA Outlook search scope to All Mailboxes?

FOUND LIST (slipstick.com):

Valid Search Scopes
In Outlook 2010 and Outlook 2013, you can choose between the following search scopes:

Scope                                                            Description

olSearchScopeCurrentFolder                   Limit the search to the currently selected folder.
olSearchScopeSubfolders                         Limit the search to the currently selected folder and its subfolders. To search all
                                                                      folders in one data file, select the top level of the pst.
olSearchScopeAllFolders                          Search all folders (of the current folder type). This search includes all data stores that
                                                                      are enabled for search.
olSearchScopeAllOutlookItems              Search all Outlook items in all folders in stores that are enabled for search.

olSearchScopeAllOutlookItems is what you really need because stores = mailboxes in your case.
