Office Online Server on Windows Server 2019

While the latest release of Office Online Server came out post-Windows Server 2019, it now looks like the product group has no plans to support Office Online Server with Windows Server 2019. That is a bit of a disappointment as Windows Server 2016 has some issues, a big one being the time it takes to install Windows Updates. Jason Haak confirmed this on a GitHub comment.

What does this mean for the future on-prem releases of SharePoint? I don’t know, but I can only ask that we some day be able to hook in and consume the cloud-based Office Online, further enhancing a hybrid story. This would go a long ways to fixing the licensing restriction preventing the deployment of Office Online Server to Azure and other cloud providers.

A Flow Button for SharePoint Server 2019

Microsoft Flow is an cloud workflow/IFTTT-alike service. You can (and should!) use Flow with SharePoint Server 2019 as a replacement for many classic SharePoint 2010 or 2013 workflow features. But one thing is missing - there’s no Flow button on Document Libraries or Lists, so I went ahead and created one.


At the moment, this command extension is very simple. It just supplies a button that drives the user to Flow, but sometimes a button is enough to get a user to think “what can I do with this?”, and that alone is a success. If anyone has thoughts about further integration, you’re absolutely welcome to contribute to the source.

Installation is simple: grab the current release, upload it to your farm App Catalog, then add it like any other app to each site. No further configuration is required.

Note that the icon color for the button will not follow your site theme. Unfortunately command extension icons cannot be set dynamically in SPFx 1.41.
