Disable ‘A program is trying to access e-mail address information stored in Outlook…’ dialog in Outlook 2007 using group policy

I have a client with an application that requires access to their outlook inbox, the problem is that every 10 minutes the users get prompted with a message that says

‘A program is trying to access e-mail address information stored in Outlook. If this is unexpected, click Deny and verify your antivirus software is up-to-date.

For more information about e-mail safety and how you might be able to avoid getting this warning, click Help.

Allow access for ____________’

Normally you’d not want to disable this warning, but my users are locked into a internet disabled Terminal Services environment, and they don’t need to worry about this. I wanted to disable this warning for all of them at once, so a GPO was in order.

Here is how you can disable it for all users at once:

  1. First, download and install the Office 2007 ADM templates from here.
  2. Extract them to your Domain controller, and then open Group Policy Management Console.
  3. Create a new GPO and link it to the OU containing the user accounts in question
  4. Right click the new Policy and click “Edit…”
  5. Expand User Configuration > Administrative Templates
  6. Right click on Administrative Templates and select “Add/Remove Templates…”
  7. Click “Add…”
  8. Browse to the directory where you extracted the ADM files and then select ‘outlk12.adm’. Click Open. Click ‘Close’.
  9. Expand Administrative Templates > Microsoft Office Outlook 2007 > Security >
  10. Double Click on ‘Programmatic Access Security’
  11. Set it to ‘Enabled’ and then select ‘Never warn me about suspicious activity (not recommended)’
  12. Close the GPO and Exit GPMC.msc.

Thats it, outlook will now suppress the warning and allow access to the application requesting access to the user’s outlook information.
