Search by Email address with urn:schemas - vba

Question

I found this code from Ricardo Diaz. It runs through.
I would like to search for the latest email I received or sent to a specific email address as opposed to search by subject.
I replaced
searchString = "urn:schemas:httpmail:subject like '" & emailSubject & "'"
with
searchString = "urn:schemas:httpmail:to like '" & emailSubject & "'"
The search returns an empty object.
What is the urn:schemas to search for the email address of the sender and receiver in my Outlook Inbox and Sent Items?
This is the code I am trying to run:
In a VBA module:
Public Sub ProcessEmails()
Dim testOutlook As Object
Dim oOutlook As clsOutlook
Dim searchRange As Range
Dim subjectCell As Range
Dim searchFolderName As String
' Start outlook if it isn't opened (credits: https://stackoverflow.com/questions/33328314/how-to-open-outlook-with-vba)
On Error Resume Next
Set testOutlook = GetObject(, "Outlook.Application")
On Error GoTo 0
If testOutlook Is Nothing Then
Shell ("OUTLOOK")
End If
' Initialize Outlook class
Set oOutlook = New clsOutlook
' Get the outlook inbox and sent items folders path (check the scope specification here: https://learn.microsoft.com/en-us/office/vba/api/outlook.application.advancedsearch)
searchFolderName = "'" & Outlook.Session.GetDefaultFolder(olFolderInbox).FolderPath & "','" & Outlook.Session.GetDefaultFolder(olFolderSentMail).FolderPath & "'"
' Loop through excel cells with subjects
Set searchRange = ThisWorkbook.Worksheets("Sheet1").Range("A2:A4")
For Each subjectCell In searchRange
' Only to cells with actual subjects
If subjectCell.Value <> vbNullString Then
Call oOutlook.SearchAndReply(subjectCell.Value, searchFolderName, False)
End If
Next subjectCell
MsgBox "Search and reply completed"
' Clean object
Set testOutlook = Nothing
End Sub
In a class module named clsOutlook:
Option Explicit
' Credits: Based on this answer: https://stackoverflow.com/questions/31909315/advanced-search-complete-event-not-firing-in-vba
' Event handler for outlook
Dim WithEvents OutlookApp As Outlook.Application
Dim outlookSearch As Outlook.Search
Dim outlookResults As Outlook.Results
Dim searchComplete As Boolean
' Handler for Advanced search complete
Private Sub outlookApp_AdvancedSearchComplete(ByVal SearchObject As Search)
'MsgBox "The AdvancedSearchComplete Event fired."
searchComplete = True
End Sub
Sub SearchAndReply(emailSubject As String, searchFolderName As String, searchSubFolders As Boolean)
' Declare objects variables
Dim customMailItem As Outlook.MailItem
Dim searchString As String
Dim resultItem As Integer
' Variable defined at the class level
Set OutlookApp = New Outlook.Application
' Variable defined at the class level (modified by outlookApp_AdvancedSearchComplete when search is completed)
searchComplete = False
' You can look up on the internet for urn:schemas strings to make custom searches
searchString = "urn:schemas:httpmail:to like '" & emailSubject & "'"
' Perform advanced search
Set outlookSearch = OutlookApp.AdvancedSearch(searchFolderName, searchString, searchSubFolders, "SearchTag")
' Wait until search is complete based on outlookApp_AdvancedSearchComplete event
While searchComplete = False
DoEvents
Wend
' Get the results
Set outlookResults = outlookSearch.Results
If outlookResults.Count = 0 Then Exit Sub
' Sort descending so you get the latest
outlookResults.Sort "[SentOn]", True
' Reply only to the latest one
resultItem = 1
' Some properties you can check from the email item for debugging purposes
On Error Resume Next
Debug.Print outlookResults.Item(resultItem).SentOn, outlookResults.Item(resultItem).ReceivedTime, outlookResults.Item(resultItem).SenderName, outlookResults.Item(resultItem).Subject
On Error GoTo 0
Set customMailItem = outlookResults.Item(resultItem).ReplyAll
' At least one reply setting is required in order to replyall to fire
customMailItem.Body = "Just a reply text " & customMailItem.Body
customMailItem.Display
End Sub
The cells A2:A4 in Sheet1 contain email address such as rainer#gmail.com for instance.

You can get to what appears to be "urn:schemas:httpmail:to" another way.
Read MAPI properties not exposed in Outlook's Object Model
The usefulness is still to be proven as the values from the the address-related properties are either not available or trivial.
