We are recommending our client to use Office Online Server(OOS) for their new project (in Sharepoint2019) on document view capabilities. We found in the Web/MSDN Blogs are saying that OOS is supported only in Windows Server 2016.But, They want to upgrade all their Servers to Windows Server 2019.Here are the following questions that we have.
1.After Windows 2016 is Expired, what is the way forward for Office online server.?
2.Do we have any thing else to achieve this functionality apart from Office Online Server as this has limited support?
