delegate rights email - how can u leave it as unread when u read

[Guest]

When you have delegate rights to your bosses email, once you read the message
from your machine, how can you make sure that it remains as unread in their
inbox?

I would suggest marking the e-mail as unread until your boss has read it and
perhaps use categories to state whether it has been read by yourself your
boss or both of you.

That is a good idea. But in my previous position, it didn't matter what I
did to the emails that I read, they always remained unread in my bosses inbox
until he had read them so I presume it must be something within the settings
that I have wrong.

Any advice?
