This is a version of the macro and userform from Select from a list of subjects before sending a message and uses a userform to display a list of templates to select from to create a new message to the selected contact.

Create the Userform

1. Right click on Project1 and select Insert > UserForm
2. Open the control Toolbox and select a ComboBox and add it to the UserForm.
3. Add a Command button.
4. Right click on the Command button and choose Properties.
5. Type OK (or Use Template) in the Caption field.
6. Type btnOK in the (Name) field.



7. Right click on the UserForm and choose View Code.
8. Paste the code below into the code window.
9. Change the Template display names as desired. This list is for your reference only, not the actual template file name. The filename is set in the VBA macro code.

Private Sub UserForm_Initialize()
  With ComboBox1
    .AddItem "Potential client"
    .AddItem "New client welcome letter"
    .AddItem "Work order approval"
    .AddItem "Existing client"
    .AddItem "Payment overdue"
    .AddItem "Invoice"
  End With
End Sub

Private Sub btnOK_Click()
    lstNum = ComboBox1.ListIndex
    Unload Me
End Sub

Note, you will need to have a reference to the Forms library in Tools, References.

If you receive a "User-defined type not defined" you are missing the reference to Microsoft Forms 2.0 Object Library. If its not listed, add C:\Windows\System32\FM20.dll or C:\Windows\FM20.dll as a reference.

Macro to call the UserForm

1. Right click on Project1 and choose Insert > Module.
2. Paste the code below into the Module.
3. Change the template filenames in strTemplate.

Select a contact then run the macro to test it.

Public lstNum As Long

Public Sub ChooseTemplate()

Dim oMail As Outlook.MailItem
Dim oContact As Outlook.ContactItem

If TypeName(ActiveExplorer.Selection.Item(1)) = "ContactItem" Then
 Set oContact = ActiveExplorer.Selection.Item(1)

Dim strTemplate As String
   UserForm1.Show

    Select Case lstNum
    Case -1
'  -1 is what you want to use if nothing is selected
         strTemplate = "template-1"
    Case 0
         strTemplate = "template-1"
    Case 1
        strTemplate = "template-2"
    Case 2
         strTemplate = "template-3"
    Case 3
         strTemplate = "template-4"
    Case 4
         strTemplate = "template-5"
    End Select

    strTemplate = "C:\Users\me\Templates\" & strTemplate & ".oft"
    Set oMail = Application.CreateItemFromTemplate(strTemplate)

With oMail
  .To = oContact.Email1Address
  .ReadReceiptRequested = True
  .Subject = "My Macro test"
  .Body = "Hi " & oContact.FirstName & "," & vbCrLf & vbCrLf & oMail.Body
  .Display
End With
  End If
Set oMail = Nothing

End Sub

Create a toolbar button

You can create a ribbon or QAT button for the ChooseTemplate macro so it's easier to start the macro.
