Integrate your business solutions into Outlook
Use the power of event-based add-ins
Enable users to access your solutions via common Outlook actions such as composing a new email, adding a recipient, or adding an attachment.
Enable better collaboration in a hybrid working environment
Help your users to be more productive in hybrid or remote environments by sending better emails. Smart Alerts events such as OnMessageSend and OnAppointmentSend allow your users to improve their emails and meeting invites before they're sent.
Build contextually rich email experiences across platforms
Outlook add-ins provide the right information and expose relevant tasks in the context of an email communication at the right time, such as when you're composing or reading an email. And, Outlook add-ins work across Windows, Mac, Android, iOS, and the web.
