Currently dealing with an Outlook issue for one of my clients. Outlook does not display images contained in email. Traffic forwarding for the client is via PAC file URL contained in browser. When we point user to their local proxy, Outlook displays the images contained in emails. When we point user to Zscaler via PAC file, Outlook does not display the images.
I believe Zscaler is configured correctly. I suspect some type of incompatibility between Outlook and PAC file URL used to point user Internet traffic to Zscaler.
Any suggestions on how to resolve are greatly appreciated.
