When I create a signature in Outlook it is single line spaced but when I create a new email or insert a signature it is double line spaced and I cannot change it.

Also, how can I create a signature including graphics? I have created an HTML file but the logo doesn't show in the signature.

Also, when composing an email and I insert a link it doesn't work as a link, it is just text. is there an option I need to select?

Any help gratefully appreciated
