Mail Merge in Office 2010

I am trying to send a mail to a number of recipients using Mail Merge in Office 2010 as I do not want the other recipients to see everyone's e-mail addresses. I have managed to get to the point of setting up the mail through MS Word, but when I hit "Send" I get a popup dialog which 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." I can allow access for 1 to 10 minutes and then I have to click either Allow, Deny, or Help.

The problem is that I have to click Allow for each message before it will go through. The mail is going to quite a large number of people, and I need to send it in PLAIN TEXT. Is there any way I can "Allow All" or reduce the security settings so that I can just send this mail in one go?

Thanks a lot.

Have you tried modifying the Programmatic Access settings in Outlook's Trust centre?

Hi Graham. Thank you for your suggestion. I went to the Trust Centre, but the Programmatic Access says that the Anti-Virus status is Valid and all the options are greyed out.

"Warn me about suspicious activity when my antivirus software is inactive or out-of-date" is checked and the other two options are just about warning me about suspicious activity so probably not relevant.
There is an MS article on this topic

Hope this helps
