Collabora Online with recent SharePoint versions (Subscription Edition, 2019) – feedback?

Hello everyone,

We are currently evaluating Collabora Online in a Kubernetes/OpenShift environment and trying to understand the feasibility of integrating it with recent on-prem SharePoint versions, particularly SharePoint Subscription Edition (and potentially SharePoint 2019).

I’ve come across Collabora materials and demos showing integration with SharePoint 2016 via WOPI, including the use of WOPI bindings. However, I haven’t found clear or up-to-date information regarding:

  • Compatibility with newer SharePoint versions (Subscription Edition / 2019)

  • Whether the previous WOPI-based approach is still valid or supported (from my understanding Collabora is entirely WOPI-based and I don’t know how well latest Sharepoint’s Wopi implementations behave with Collabora)

  • Any known limitations, regressions, or required workarounds ? Eventually real-world production feedback (stability, supported features, etc.)

In other words, my questions are:

  1. Is there any official or semi-official support / demo/ etc for integrating Collabora Online with recent SharePoint on-prem versions?

  2. Has anyone in the community successfully implemented this with SharePoint Subscription Edition? And if so any feedback on pitfalls or recommended configurations?

Thanks a lot in advance for any help or feedback!
