We have a solution that generates custom x-header on all emails (via an Outlook Add-in). Using Outlook, User A creates a server-side rule which forwards messages onto User B. User B receives a message without the custom x-header. My question is how can I retain the custom x-header, at the moment I cannot think of any way!
The server-side rule can use 'forward as attachment' which keeps the custom x-header in the attached message, but the 'inline forward' action (where the forward message is embedded into the body of the new message) doesn't. Requirement is for both types of forwarding to function!
Thanks
