Novell GroupWise 2014 R2
You create a new mail where you do not add recipient yet. Once it gets auto-saved, you close it and later you open the same mail from Work In Progress folder. That opens in some sort of posted / sticky note.
Other case is that after you have a text in a message body, a mail gets auto-saved and then you add recipient to the mail and wait for a second auto-save cycle .. close it and later open it from Work In Progress folder, a text in a message body is lost.
This does not happen when you add recipient to such draft mail right after you compose it.
This has been reported to the development.
