I have installed SharePoint server 2019 on 4 servers in minrole configuration. The installation went without issues. However, there is no option to create new documents (word excel etc.) when you hit on "New" button in the document library. (only folder and link options are visible).
Is it really necessary to install OOS or this option for creation on new documents should come out of the box?
Do you have any ideas what the issue can be?
