Guess none of you display URLs in your outbound emails then!
After raising a ticket (which is still unanswered (properly) by Genesys after 5 days) I decided to apply a combination of brawn and brains to the problem myself, and tried every combination of workarounds I could possibly think of.
The end result - I can now properly embed a URL (fetched as a Field Code) into the email text, properly within href tags.
I do not understand what is your problem. Inserting of Interaction/contact or any other data to the URL is possible. For example we are using inserting of attach file name as a query string in URI.
The fact that someone is displayed/processed in Outlook and in Genesys no, is given by failure RFC compliant from Outlook site.
Have you tried escaping the contents of the href tag (from an HTML perspective) by using a double set of quotes rather then the standard singles (“”“”)?
