This worked well, and the site is correctly running over https 443, with no change to the config. Thanks to the backup restore :)

However, the only glitch is that all of the embedded hyperlinks in the emails sent from SD+ have the URL going to http, when they should be httpS

Ex:

Wrong: click here for the open your request http://servicedesk.domain.com

Correct: click here for the open your request http S://servicedesk.domain.com

There's got to be a conf somewhere which forces the embedded links to added the S (SSL) ???

Any help would be appreciated, as users a clicking on links and saying the Service Desk is down, when it's not. 

Thanks,
