I have a user who is getting the red Application Modification detected warning, referring to MS Outlook. The warning refers to Outlook.exe This appears to have happened after I did various updates last week, MS updates including SP3 for Office 2003. He is using Windows XP, and Outlook 2003. The problem is that we cannot either Deny or Approve. I'm assuming this is because he's not logged on as administrator (domain user). But because this is an Outlook related problem, he needs to log on as himself, not administrator. Note that this user is a member of the Administrators group. Has anyone ever seen something like this ? Any ideas what I can try ?
