To showcase the amazing scenarios being enabled, we partnered with three ISVs specializing on e-mail signature solutions who are using both the on compose events and the Mailbox 1.10 signature APIs at the core of their functionality. This combined with the release of the Mailbox 1.10 APIs unlocks the long-awaited Signature Scenario where add-ins can add custom signatures to a newly created message or appointment without the user needing to take any action. For this first release of events, you can launch add-ins automatically when composing messages or appointments using the on compose events. New event-based add-ins for OutlookĮvent-based add-ins enable developers to surface their add-in capabilities based on user actions within Outlook. For more detail, please see the Outlook and Excel on-demand sessions at Build. These new features will help bring your business solutions more seamlessly into Office. Welcome to Build 2021! We are excited to share six new Outlook and Excel announcements that we think are particularly exciting for our Office developer community.
