Re: S1 shortcutting for address books and tasks, Outlook 2010 support
Source One 6.5 only supports shortcutting of Email Messages.
Source One 6.6 only supports shortcutting of Email Messages and Calendar entries.
As for Outlook 2010 support with Source one. Outlook 2010 will open Universal URL type of Shortcut natively since they are basically an URL that you click on.
If you are looking for a client that supports Outlook 2010 ie : Offline Access then, at this time we don't have a version of Offline Access that works/ is supported with Outlook 2010. Engineering is working on it , however at this time EMC does not have a timeline on a release date.
