With Pegasus Mail open, click the Help menu item, then click "About Pegasus Mail". Then click the Info button. You will get a screen with a lot of different information.

The item you need is "Home mailbox location".  Note the location.

Next using Windows Explorer, navigate to that address. To make things easier at this point, click on the heading for Type, to get the directory content sorted by filetype.

Scroll down till you find the Pns files. Select any/all of these files, and click Delete .  You are done.  Close and then restart Pegasus Mail, and your signature files are gone.

... and  not use any now.

I went to tools, options, outgoing mails, signatures and tried editing - to no avail.

Can't find the correct button to click for cancellation of all signatures. 

Please advise.

Try deleting any file with filetype PNS in your Newmail folder to remove any active definitions

Thank you Martin,

and how exactly do I do this?

Where do I see the filetype PNS?
