Outlook Signature use starts at the top of the message.

I have a number of outlook email accounts and therefore have a number of signatures.  The signature I have created runs to the very start of the message.  Therefore when typing the message it is acutally being entered into the "signature area".  If I change the signature or the sedning account (therefore changing the signature), it deletes the whole message (as it was typed into the signature area)

I'm sure there is some setting somewhere that allows blank lines before the signature somewhere.

Any tips please
