How to identify emails where sender is also a recipient?

I'm trying to export sender email address and recipient email addresses (to and cc) to Excel. I adapted code I found online. It does most of what I need but there are two problems:

• It only works with a single recipient. If there are two or more recipients, it provides names (e.g. Jo Bloggs) instead of email addresses.
• It only includes people in the 'To' field, not those in the 'CC' field.

I think the bit that needs fixing is:

'trying to get recipient email address
 Dim olEU2 As Outlook.ExchangeUser
 Dim oEDL2 As Outlook.ExchangeDistributionList
 Dim recip2 As Outlook.Recipient
 Set recip2 = Application.Session.CreateRecipient(strColE)

     Select Case recip2.AddressEntry.AddressEntryUserType
       Case OlAddressEntryUserType.olExchangeUserAddressEntry
         Set olEU2 = recip.AddressEntry.GetExchangeUser
         If Not (olEU2 Is Nothing) Then
             strColE = olEU2.PrimarySmtpAddress
         End If
       Case OlAddressEntryUserType.olOutlookContactAddressEntry
         Set olEU2 = recip.AddressEntry.GetExchangeUser
         If Not (olEU2 Is Nothing) Then
            strColE = olEU2.PrimarySmtpAddress
         End If
       Case OlAddressEntryUserType.olExchangeDistributionListAddressEntry
         Set oEDL2 = recip.AddressEntry.GetExchangeDistributionList
         If Not (oEDL2 Is Nothing) Then
            strColE = olEU2.PrimarySmtpAddress
         End If
     End Select

Iterating through all items in the folder is not really a good idea. I'd recommend starting from the Find/FindNext or Restrict methods instead. Please note that there are some item properties that you can’t use for the filter. You can read more about the properties not allowed in the filter string and string formats used for the search criterion on MSDN.

The following example uses the Restrict method to get all Inbox items of Business category and moves them to the Business folder. To run this example, create or make sure a subfolder called 'Business' exists under Inbox:

Sub MoveItems()  
    Dim myNamespace As Outlook.NameSpace  
    Dim myFolder As Outlook.Folder  
    Dim myItems As Outlook.Items  
    Dim myRestrictItems As Outlook.Items  
    Dim myItem As Outlook.MailItem  
  
    Set myNamespace = Application.GetNamespace("MAPI")  
    Set myFolder = _  
        myNamespace.GetDefaultFolder(olFolderInbox)  
    Set myItems = myFolder.Items  
    Set myRestrictItems = myItems.Restrict("[Categories] = 'Business'")  
    For i =  myRestrictItems.Count To 1 Step -1  
        myRestrictItems(i).Move myFolder.Folders("Business")  
    Next  
End Sub

Also, you may find the AdvancedSearch method of the Application class helpful. The key benefits of using the AdvancedSearch method in Outlook are:

• The search is performed in another thread. You don’t need to run another thread manually since the AdvancedSearch method runs it automatically in the background.
• Possibility to search for any item types: mail, appointment, calendar, notes etc. in any location, i.e. beyond the scope of a certain folder. The Restrict and Find/FindNext methods can be applied to a particular Items collection (see the Items property of the Folder class in Outlook).
• Full support for DASL queries (custom properties can be used for searching too). You can read more about this in the Filtering article in MSDN. To improve the search performance, Instant Search keywords can be used if Instant Search is enabled for the store (see the IsInstantSearchEnabled property of the Store class).
• You can stop the search process at any moment using the Stop method of the Search class.

Please remember that you can set a suitable filter (View | View Settings |filter) on a folder and study the filter string on the SQL tab of the Filter dialog. Then you can construct any required filter string in the code.

If woudl be nice to use Items.Find/FindNext or Items.Restrict, but I cannot think of a query that would let you do what you want. If it is a one time thing, you have no choice but to loop through all items in a folder and for each item loop through all recipients and compare each recipient's entry id (Recipient.EntryID) with the sender entry id (MailItem.Sender.EntryId).
