Janusnet have updated the code for their Janusseal App for Outlook to make it operational in Microsoft Outlook 2016 for Mac. Outlook Mac users will then be able to apply and inspect security classifications on messages and calendar items.
The update also makes Janusseal App for Outlook easier to access from within Outlook 2016 on Windows machines - when composing a message there is a new "Classify" button in the toolbar that opens Janusseal's classification pane.
Organisations can choose when to unlock these enhancements - all they have to do is to re-install the app/add-in in their Exchange Control Panel and the changes will be available to end-users a short time thereafter (note - in Office 365 environments it can take several hours for the previous version of the app to be de-registered and then for the new version to be made available).
