Microsoft is continually evolving its products to deliver greater functionality, stronger security, and better experiences for users. That evolution is now underway for Outlook as we transition from classic Outlook to the new Outlook for Windows, a move that accelerates access to innovations like Copilot and other AI-native tools essential for success in today’s business landscape.
Users are already asking for their most critical productivity apps to be ready for this change. And just as App Assure helped software companies transition from Exchange Tokens to Nested App Authentication earlier this year, we now stand ready to help you make the transition to new Outlook seamless and worry-free.
Benefits of new Outlook
Outlook is your organization’s hub for communication and collaboration. With the transition from COM add-ins to Web add-ins, new Outlook for Windows empowers both customers and partners alike.
- Customers receive a streamlined interface that provides a consistent user experience across devices and AI-native tools built directly into Outlook, all while benefiting from a lower total cost of ownership and quicker access to new features.
- Partners benefit from Microsoft’s deep investment in extensibility, allowing them to reach the entire Outlook audience whether those users are working via Windows, Mac, Mobile, or web.
This is why App Assure has been working proactively with the most popular add-ins, collaborating with software companies to update, test, validate, and publish their solutions for the new Outlook. Our goal is simple: when customers make the switch, their essential tools are ready to go, with no disruption and no surprises. Most of the 14 most common scenarios for COM add-ins, those that make up 95% of how COM add-ins are actually used, can already be handled by web add-in APIs either fully or at a basic “minimum viable product” (MVP) level.
Ecosystem Readiness for our Customers
One such app beloved by customers is Applications for Administrative Solutions (AFAS), whose Outlook add-in helps streamline Enterprise Resource Planning (ERP) workflows by integrating email-driven tasks directly into daily operations. To ensure a smooth transition to the new Outlook, AFAS partnered with App Assure to modernize their add-in using Graph API to facilitate moving from COM add-ins to web add-ins, aligning with enterprise-grade security and Microsoft Entra policies. Through collaborative testing, technical validation, and direct support from App Assure engineers, AFAS was able to update and publish their add-in with confidence, ensuring that customers won’t miss a beat when they move to new Outlook.
But AFAS is just one example. Many software companies have been preparing their mission critical apps for new Outlook with App Assure’s guidance. Here are a number of the most recent software companies we’ve worked with (with many more on the way):
Many of our partners remark on how streamlined their updates are with App Assure’s collaboration and how easy it is to work with our team. Here are a couple of their recent comments:
