I have a client who is upgrading to SharePoint Server 2019 but keeping Office 2016. I am well versed with the co-authoring capabilities between SharePoint Online and Office 365, but I have no idea what co-authoring would look like with SP 2019/Office 2016 combination.
Has anybody seen the SP 2019/Office 2016 combination in practice? I would appreciate any insight you can share. Thanks!
