When a mailbox receives messages for more than one address, such as messages forwarded from another account, Outlook may include the address in the recipients list when you hit Reply All.
I have an issue with reply all in outlook 2013. Since I use gmail, I effectively have 2 email addresses, with the same account (@gmail.com, @googlemail.com) If I reply all to an email sent to @googlemail.com, I get cc'd on the reply as outlook doesn't recognize the address as the same as the account its set up with.
This isn't a new problem: Outlook has always had problems identifying which address is yours when it doesn't match the address on your account in Account Settings.
To remove the address, use a macro that runs when you trigger the Reply All command.
Paste the following macro in ThisOutlookSession. To test it without restarting Outlook, click in the Startup macro and press F5 or the Run button.
This macro will be triggered by the Reply All button in the Reading Pane but the reply opens in a new window.
Option Explicit Private WithEvents oExpl As Explorer Private WithEvents oItem As MailItem Private bDiscardEvents As Boolean '//slipstick.me/44b0w Private Sub Application_Startup() Set oExpl = Application.ActiveExplorer bDiscardEvents = False End Sub Private Sub oExpl_SelectionChange() On Error Resume Next Set oItem = oExpl.Selection.Item(1) End Sub ' Reply Private Sub oItem_ReplyAll(ByVal Response As Object, Cancel As Boolean) Cancel = True bDiscardEvents = True Dim oReply As MailItem Set oReply = oItem.ReplyAll Dim recips As Outlook.Recipients Dim i As Long Set recips = oReply.Recipients For i = recips.Count To 1 Step -1 If LCase(recips.Item(i).Address) = "firstname.lastname@example.org" Then recips.Remove i End If Next oReply.Display bDiscardEvents = False Set oItem = Nothing End Sub
How to use the macro
First: You will need macro security set to low during testing.
To check your macro security in Outlook 2010 or 2013, go to File, Options, Trust Center and open Trust Center Settings, and change the Macro Settings. In Outlook 2007 and older, it’s at Tools, Macro Security.
After you test the macro and see that it works, you can either leave macro security set to low or sign the macro.
Open the VBA Editor by pressing Alt+F11 on your keyboard.
To use the macro code in ThisOutlookSession:
- Expand Project1 and double click on ThisOutlookSession.
- Copy then paste the macro into ThisOutlookSession. (Click within the code, Select All using Ctrl+A, Ctrl+C to copy, Ctrl+V to paste.)
