McAfee is blocking Outlook .ics invites
Some stand-alone versions of McAfee Endpoint Security are blocking .ics calendar invites, preventing them from being downloaded or displaying a message that the file is violating the rule "Microsoft Outlook VEVENT Vulnerability".
This has been corrected in the latest download, but to change this rule without upgrading, do the following:
- Right click the McAfee shield in the system tray icon and select McAfee Endpoint Security
- Click on Threat Prevention
- Click Show Advanced
- Click Exploit Prevention
- Scroll down to the 'Quick find' box in the Signatures section and enter Vevent
- Rule 3809 should be shown, uncheck the block and report settings options.
- Click apply
