extract email address from outlook - vba

Question

I am trying to extract email addresses of all emails in my Outlook inbox. I found this code on the Internet.
Sub GetALLEmailAddresses()
Dim objFolder As MAPIFolder
Dim strEmail As String
Dim strEmails As String
''' Requires reference to Microsoft Scripting Runtime
Dim dic As New Dictionary
Dim objItem As Object
''Set objFolder = Application.ActiveExplorer.Selection
Set objFolder = Application.GetNamespace("Mapi").PickFolder
For Each objItem In objFolder.Items
If objItem.Class = olMail Then
strEmail = objItem.SenderEmailAddress
If Not dic.Exists(strEmail) Then
strEmails = strEmails + strEmail + vbCrLf
dic.Add strEmail, ""
End If
I am using outlook 2007. When I run this code from the Outlook Visual Basic Editor with F5 I get an error on the following line.
Dim dic As New Dictionary
"user defined type not defined"

Answer 1

I have provided updated code below
to dump the Inbox email addresses to a CSV file "c:\emails.csv" (the current code provides no "outlook" for the collected addresses
the code above works on a selected folder rather than Inbox as per your request
[Update: For clarity this is your old code that uses "early binding", setting this reference is unnecessary for my updated code below which uses "late binding"]
Part A: Your existing code (early binding)
In terms of the error you received:
The code sample aboves uses early binding, this comment "Requires reference to Microsoft Scripting Runtime" indciates that you need to set the reference
Goto the Tools menu
Select 'References'
check "Microdoft Scripting Runtime"
Part B: My new code (late binding - setting the reference is unnecessary)
Working Code
Sub GetALLEmailAddresses()
Dim objFolder As MAPIFolder
Dim strEmail As String
Dim strEmails As String
Dim objDic As Object
Dim objItem As Object
Dim objFSO As Object
Dim objTF As Object
Set objDic = CreateObject("scripting.dictionary")
Set objFSO = CreateObject("scripting.filesystemobject")
Set objTF = objFSO.createtextfile("C:\emails.csv", 2)
Set objFolder = Application.GetNamespace("Mapi").GetDefaultFolder(olFolderInbox)
For Each objItem In objFolder.Items
If objItem.Class = olMail Then
strEmail = objItem.SenderEmailAddress
If Not objDic.Exists(strEmail) Then
objTF.writeline strEmail
objDic.Add strEmail, ""
End If
End If
Next
objTF.Close
End Sub

export the file to C:\Users\Tony\Documents\sent file.CSV
Then use ruby
email_array = []
r = Regexp.new(/\b[a-zA-Z0-9._%+-]+#[a-zA-Z0-9.-]+\.[a-zA-Z]{2,4}\b/)
CSV.open('C:\Users\Tony\Documents\sent file.CSV', 'r') do |row|
email_array << row.to_s.scan(r)
end
puts email_array.flatten.uniq.inspect

Here's an updated version for those using Exchange. It converts Exchange format addresses to normal email addresses (with the # symbol).
' requires reference to Microsoft Scripting Runtime
Option Explicit
Sub Write_Out_Email_Addresses()
' dictionary for storing email addresses
Dim email_list As New Scripting.Dictionary
' file for output
Dim fso As New Scripting.FileSystemObject
Dim out_file As Scripting.TextStream
Set out_file = fso.CreateTextFile("C:\emails.csv", True)
' open the inbox
Dim ns As Outlook.NameSpace
Set ns = Application.GetNamespace("MAPI")
Dim inbox As MAPIFolder
Set inbox = ns.GetDefaultFolder(olFolderInbox)
' loop through all items (some of which are not emails)
Dim outlook_item As Object
For Each outlook_item In inbox.Items
' only look at emails
If outlook_item.Class = olMail Then
' extract the email address
Dim email_address As String
email_address = GetSmtpAddress(outlook_item, ns)
' add new email addresses to the dictionary and write out
If Not email_list.Exists(email_address) Then
out_file.WriteLine email_address
email_list.Add email_address, ""
End If
End If
Next
out_file.Close
End Sub
' get email address form a Mailoutlook_item
' this entails converting exchange format addresses
' (like " /O=ROOT/OU=ADMIN GROUP/CN=RECIPIENTS/CN=FIRST.LAST")
' to proper email addresses
Function GetSmtpAddress(outlook_item As Outlook.MailItem, ns As Outlook.NameSpace) As String
Dim success As Boolean
success = False
' errors can happen if a user has subsequently been removed from Exchange
On Error GoTo err_handler
Dim email_address As String
email_address = outlook_item.SenderEmailAddress
' if it's an Exchange format address
If UCase(outlook_item.SenderEmailType) = "EX" Then
' create a recipient
Dim recip As Outlook.Recipient
Set recip = ns.CreateRecipient(outlook_item.SenderEmailAddress)
' extract the email address
Dim user As Outlook.ExchangeUser
Set user = recip.AddressEntry.GetExchangeUser()
email_address = user.PrimarySmtpAddress
email_address = user.Name + " <" + user.PrimarySmtpAddress + ">"
success = True
End If
err_handler:
GetSmtpAddress = email_address
End Function

In outlook, export a folder to a csv file, then open in Excel. A simple MID function should be able to extract the email address if it's not been placed in a "from" column already.
