Fix for mailto links open with Lotus Notes or Microsoft Outlook

1) Open regedit.exe

2) Navigate to HKEY_CURRENT_USER\Software\Microsoft\Windows\Shell\Associations\UrlAssociations\mailto\UserChoice

3) Double click on Progid.Change it to :


On clicking mailto: links Lotus Notes will now open them automatically.

3) If you want the links to open in Outlook, do step 2 and put the below value:
Microsoft Outlook.Url.Mailto

Some example of mailto: links : was cool


  1. If you have Lotus Notes 8.5.3, you should also check this:

    "URL Protocol"=""

    This solved my problem on Citrix XenApp 6.5

  2. On RDS 2012 with Office 2013 use: Outlook.URL.mailto.15
