Disable 'programmatic access' security in Outlook

When certain software uses MAPI to send an email via Outlook, a warning message appears. Fair enough - the likelihood that the average Windows computer is infected with spam-generating malware is pretty high. So be thankful, dear user, that the message also has an in-built delay, preventing you from closing the dialog window until Microsoft decides you're ready. It's also in your best interests that the warning appears every fucking time.

Perhaps the friendly Trust Center will let us disable the warning? Sure - but only if you're the administrator. Then perhaps the Outlook Group Policy object will let us disable the warning? The option's there - but it doesn't work.

Who can save us from this mess? Yep. You've probably got a shortcut key set up for it by now.

HKEY_CURRENT_USER\Software\Policies\Microsoft\Office\12.0\Outlook\Security

(12 is for Outlook 2007. Change it to 14 for Outlook 2010, 15 for Outlook 2013 etc.)

For each user, create DWORDs here with the value "2" and names as follows:

PromptSimpleMAPISend
PromptSimpleMAPINameResolve
PromptSimpleMAPIOpenMessage

    1. Open Registry Editor, navigate to the key, create the DWORDs and assign them the value.

      If you don't know what the Registry Editor is or aren't comfortable using it, ask a friend or do a web search for "how to use registry editor".

  10. It's not working with my Outlook 2010 for some reason. I added the DWORD values under

    HKEY_CURRENT_USER\Software\Policies\Microsoft\Office\14.0\Outlook\Security

    DWORD (32)

    PromptSimpleMAPINameResolve 2
    PromptSimpleMAPIOpenMessage 2
    PromptSimpleMAPISend 2

    And I am still getting the prompts. What am I missing?

    1. You may need to add another DWORD called "AdminSecurityMode" with the value "3".

      You may need to try under HKEY_CURRENT_USER\Software\Wow6432Node\Microsoft\Office\14.0\Outlook\Security

      You may need to try restarting your PC (sometimes Outlook continues to run in the background, so it won't pick up these changes).

    1. You may need to try under HKEY_CURRENT_USER\Software\Policies\Microsoft\Office\16.0\Outlook\Security

      You may need to try under HKEY_CURRENT_USER\Software\Wow6432Node\Microsoft\Office\16.0\Outlook\Security

      You may need to add another DWORD called "AdminSecurityMode" with the value "3".

      You may need to add another DWORD called "ObjectModelGuard" with the value "2".

      You may need to add another DWORD called "PromptOOMSend" with the value "2".

    1. I'm sorry it's not working for you. All I can say is what does work for me, using the following:

      Microsoft Outlook 2016 32-bit
      Microsoft Windows Server 2012 R2
      MYOB AccountRight Premier v19.12

      Adding the 3 values (PromptSimpleMAPISend, PromptSimpleMAPINameResolve, PromptSimpleMAPIOpenMessage) to the registry here:

      HKEY_CURRENT_USER\Software\Policies\Microsoft\Office\16.0\Outlook\Security

      After this, Outlook no longer prompted the "Allow/Deny" window for each email sent from it.

  13. Hi,

    Must the values be in Hex or Dec for the below ?

    For each user, create DWORDs here with the value "2" and names as follows:

    PromptSimpleMAPISend
    PromptSimpleMAPINameResolve
    PromptSimpleMAPIOpenMessage
