Office 2010 generated emails don't get signature by default

When I generate an email from MS Office 2010, (ie. create a document and then ‘send as email’), an email is generated, but the default signature does not appear on the email. Is this meant to be like that? Yes, I can manually add by clicking on signature - but it should have the option really?

we are aware of that eM Client behavior. We will consider possible change of it to some of our future versions/updates.
