Excel VBA Macro to Extract Outlook GAL Email Address Using Alias

**showtime** · 08-01-2020, 07:43 PM

Hi,

In a worksheet called "Users" I have a defined named range for column A called "Aliases" which has one text data in each cell like:

VACBHAW
VTQOBRE
POTWVYZ

I would like to lookup these aliases in the Outlook Global Address List (GAL) and pull in these three fields: emails, name, and phone number. Each alias exists in Outlook GAL, if it doesn't then it should not return anything for those three fields. Keep in mind that I have hundreds of these aliases listed in column A, so I would like the code to be fast if possible. Please note I have Office 365.

I found a similar code online, but I don't know how to modify it to fit my requirement:

Code:

Sub tgr()    
    Dim appOL As Object
    Dim oGAL As Object
    Dim oContact As Object
    Dim oUser As Object
    Dim arrUsers(1 To 65000, 1 To 7) As String
    Dim UserIndex As Long
    Dim i As Long
    Dim sEmails as String
    Dim cl as Range
    Dim rngEmails as Range


    With Worksheets("Users")
        Set rngEmails = .Range("A2:" & .Range("A" & .Rows.Count).End(xlup).Address)
    End With


    For each cl in rngEmails
        If Len(cl.value)>0 Then
            sEmails = sEmails & Cl.Value & ","
        Else
            'No email in cell, ignore it
        End If
    Next cl

    Set appOL = CreateObject("Outlook.Application")
    Set oGAL = appOL.GetNamespace("MAPI").AddressLists("Global Address List").AddressEntries

    For i = 1 To oGAL.Count
        Set oContact = oGAL.Item(i)
        If oContact.AddressEntryUserType = 0 Then
           Set oUser = oContact.GetExchangeUser
            If InStr(1, sEmails, oUser.PrimarySmtpAddress, vbTextCompare) > 0 Then
                UserIndex = UserIndex + 1
                arrUsers(UserIndex, 1) = oUser.PrimarySmtpAddress
                arrUsers(UserIndex, 2) = oUser.Department
                arrUsers(UserIndex, 3) = oUser.Name
                arrUsers(UserIndex, 4) = oUser.CompanyName
                arrUsers(UserIndex, 5) = oUser.BusinessTelephoneNumber
                arrUsers(UserIndex, 6) = oUser.Alias
                arrUsers(UserIndex, 7) = oUser.MobileTelephoneNumber
                
            End If
        End If
    Next i
    appOL.Quit
    If UserIndex > 0 Then
        Range("A2").Resize(UserIndex, UBound(arrUsers, 2)).Value = arrUsers
    End If
    Set appOL = Nothing
    Set oGAL = Nothing
    Set oContact = Nothing
    Set oUser = Nothing
    Erase arrUsers
 End Sub

I detected a small issue with the code - it returns #N/A for the three extracted fields/columns from row 65,0001 to the last row of the worksheet.

Also would appreciate if you can make these small modifications:

1) Add a header for each column of the three fields such as Email, Name and Phone Number.
2) Some emails comes like joe.smith@outlook.com (there is always a period between the first and last name) and would like to capitalize the "J"and "S", some are already come in correct form so those shouldn't change.
3) The Name column comes like Smith, Joe G. (ABC Company) - is it possible to separate Joe (first name) G. (middle name) and Smith (last name) in separate columns with the appropriate headers? Code should disregard the (ABC Company)....it's always in this format "(company name)". Some people don't have a middle name so it should be blank in that column.

Thanks!!

Can you help remove the error that I detected with the code and if possible make those small modifications? You can skip or make # 3 optional (by adding the code as a comment). Thank you

This is exactly what I was looking for but it stops returning data after the first 3 rows, how would I modify to lookup like 30+ lines?
