Recently the McAfee WebAdvisor is updated. the current version is 4.0.124. After updated, If the outlook email's attachment is in rich text format, I cannot open it. The outlook will show an error "Outlook cannot open the document: user does not have access privileges.". If I change the email to html format, I can open the document. I try to uninstall the WebAdvisor, the rich text format email's attachment can open again?
I try to turn off the WebAdvisor for outlook that is suggested in this post. but it isn't work.
I locked that (Old) post as it was over 8 years old. The software has changed since then.
May I ask what Browser you are using,and your 'Software Suite' ?
Is your Anti-Spam working properly?
In my computer, there are IE11, Chrom and FireFox. I am using outlook 2013 (on window 7) for checking my email. Do you mean the webadvisor anti-spam?
