Thunderbird: Body of forwarded messages missing for other (not Thunderbird) clients
When forwarding a mail using Thunderbird via OWA, a recipient not using Thunderbird cannot see the forwarded message. The message shows correctly when the recipient uses Thunderbird, but for example in the browser using OWA the body of the forwarded message is missing. By setting the text format to "plain text only" when forwarding the message, everything is shown correctly, though that isn't a very good solution. Sending normal mails works perfectly fine.
