Just a minor annoyance: when an initial invitee delegates(let's say Jack) to another person (let's say Jim) using the "Forward", the e-mail generated by outlook has sender "{Invitee} on behalf of {Chairman}" and the picture shown is the Chairman's picture (lets say John). This is wrong because the email is sent by the initial invitee (Jack). It should be picture of the of Jack, instead of chairman John.

This is confusing to the receiver (Jim), who sees the picture of the Chairman (John) but the text written is by the initial invitee (Jack).

Question: any workaround to avoid the wrong photo showing up?

Question asked on behalf of a colleague.

It's not the wrong picture - it's the picture of the meeting organiser (John) - yes?

It's John's meeting : he is the chairperson/organiser : "on behalf of John" = John's picture.

This is how it works, when the Exchange Server is doing the work "on behalf of John"

This article discusses related topic (not exactly answering your specific question though..)

Agree only if Jack just clicked 'forward' button without adding any text of him in the invitation body.

However, as Jack modified the invitation body text (added the text that he can't join and requesting Jim to participate on behalf of him), it becomes confusing, having picture of John but appended message from Jack (http://i.stack.imgur.com/kfXFe.jpg)
