add option to right click in Outlook 2016 on windows 10 ver 2004 x64

This probably can't be done anyway
In any Outlook email that contains a hyperlink , if you right click it you have a few option. Select, Open, Copy and Who is.

none of the functions of Outlook have ever been stored in the registry AFAIK and I have no idea if adding the option of Open using Incognito or "InPrivate" to right click hyperlinks in email can be done at all.

There have been times i would like to open a link but want to do so using Incognito if possible. Copying the link and pasting it into chrome opened using incognito mode is harder than it could be. This is for Desktop Outlook 2016 not the WebPortal.

To be honest, it would be nice to have the same choice on any place I open a Hyperlink. An added choice to open "InPrivate" for Edge or "Incognito" for Chrome in the right click selections would be handy. I think i can manage to do that for URL's on my desktop by tweaking the registry but adding the same right click options in an email is not going to be easy if even possible

I don't know any way to modify or add to the rt-click options in Outlook (in my case 2010). However, if you are prepared to use VBA, the following code will work[*] if you first copy the url to the clipboard using the existing rt-click option:

Code:

Public Sub link()
'20/6/20: MNG: attempt to open browser at selected link in private window'
Dim item As DataObject, s As String
 Set item = New DataObject
 item.GetFromClipboard
 s = item.GetText
 ShellExecute 0, "open", "C:\Program Files\Mozilla Firefox\Firefox.exe", "-private-window " & s, "", vbNormalNoFocus
 Set item = Nothing
End Sub

You will need to declare the ShellExecute function first, outside any subs:

Code:

Private Declare Function ShellExecute Lib "shell32.dll" Alias "ShellExecuteA" _
 (ByVal hwnd As Long, _
  ByVal lpOperation As String, _
  ByVal lpFile As String, _
  ByVal lpParameters As String, _
  ByVal lpDirectory As String, _
  ByVal nShowCmd As Long) _
As Long

I have only tried the code for Firefox (as that is what I use). I know Chrome allows the -incognito parameter, I don't know about Edge. I completely failed to get the same thing to work using the default browser, eg:

Code:

ShellExecute 0, "Open", " -private-window " & s, "", "", vbNormalNoFocus

It didn't matter how I played with adding the 'private' bit (before or after the url (in my case 's'), or as the 4th parameter) - nothing worked. I know that hard-coding the path to Firefox is a cludge.

So you would have to put the link in the clipboard, then click on a button for the macro - I keep my few in the Quick Access toolbar. Still a pain, but maybe this is enough to get you going?
