outlook 2016 programmatic access security setting keeps resetting

(0) ShareShare

Posted on by 5

Staff is getting the warning message from outlook " A program is trying to send an email message on your behalf...."  for each EFT remittance generated from GP2016 and trying to send it out from outlook. staff has to click Allow each time to have it sent out. 

I want to get rid of this warning message and understand it's the setting in the programmatic access security. I've tried to run outlook as admin and toggled the option from "warn me..." to "never" it worked, but the setting keeps rolling back after the laptop is rebooted. 

I also tried to edit the keys in Registry 

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office\<x.0>\Outlook\Security set the key DWORD: ObjectModelGuard=2

unfortunately, the registry key doesn't stay as well. 

It's really annoying! Anyone have experience with this issue?

    Hi Derek.  I'm having the same issue with Outlook 365.  I've tried updating the win.ini reg files as mentioned above however it is still giving me the same error message.  Is there a different procedure for 365?
