Bob, do you have a mail client, like outlook, on that computer? If there is a mail client it should open up a new email with your address loaded in. Doesn’t matter if it is on a server.
You can also try to import the email button object from my other post and then just drag it into a page and change the address in the action. To import the awo, you first save it (desktop works fine) and then open up your “my library” tab in Lectora. Double click the library objects folder and then add file. Browse to where you saved the awo and select it. Now you can drag it into any project and just change the address.
