The Outlook Add-In MAILISSA improves the collaboration and communication in your company. Post e-mails in the Team Channel, where the actual communication takes place, or place your e-mails in the right business context. MAILISSA works not only with Microsoft Teams. Unlike other add-ins, MAILISSA allows you to connect your Outlook with a variety of business applications. This saves space in the Outlook Add-In bar and reduces loading times and confusion.
