What should we do now that Office Online Server support is ending?
Microsoft is ending its support for Office Online Server on December 31, 2026. This means that if your company uses this product, it is time to start planning for a change. After this date, Microsoft will no longer provide security updates, fixes, or any technical help for Office Online Server.
What is Office Online Server?
Office Online Server allowed companies to host and use browser-based versions of Word, Excel, PowerPoint, and OneNote on their own local servers. It gave people the convenience of online Office apps within a private, on-premise environment.
Why is Support Ending?
The way we work has changed. More companies now use cloud-based tools. Microsoft is focusing its efforts on its cloud solution, Microsoft 365, which includes Office for the web. By ending support for the older server product, Microsoft can invest more in improving the features and security of its main Microsoft 365 offerings. This shift helps them provide a more consistent and modern experience for everyone.
What You Should Do Next
Continuing to use Office Online Server after support ends is a security risk. Without updates, your systems could become vulnerable. It is important to begin planning your transition away from it soon.
- Assess your current use. Understand how your teams use Office Online Server and what for. This will help you plan a smooth transition.
- Explore Microsoft 365. Learn about Office for the web and the different Microsoft 365 plans. See how its features can replace and improve upon what you do with Office Online Server.
- Create a migration plan. Work with your IT department to outline the steps for moving your users and data to Microsoft 365. Set a timeline to ensure you complete the switch well before the December 2026 deadline.
- Communicate with your team. Keep your users informed about the upcoming changes. Provide training and support to help them adapt to the new system smoothly.
Starting this process early will help your organization move to a more modern and secure platform without disrupting your work.
