I had thought to include an HTML field on the Employee table, and then create an initialization rule to insert that field into the EmailBody. The trouble is that it doesn't work.
Use case: I would like to open an existing ticket. In the journal section, click Create - Email. When I do so, I would like my signature to be pre-populated. I would like to to work for replies and forwards as well.
However, if there is another way to tackle this issue, I'm open to that. For example, if there is some way to take the default Outlook email signature, that would be even better.
