Add ItemSend event (so add-in can cancel email)

Thanks for your feedback! This is something we’re currently investigating. We’ll keep you posted.

On new item even will be useful as well.
Although that request is for Excel and Word, the same events are needed in Outlook addin to aid in development of apps that work the same as current client addins work.
