Browser details
Review the details of the web browser that you have or plan to use in your organization to make sure that the web browser works with SharePoint Server 2016 and 2019, and according to your business needs.
Internet Explorer and older functionality
Note
Some older SharePoint functionality that relies on NPAPI or ActiveX will not work on browsers other than Internet Explorer. You can work around each of these issues by using Internet Explorer to perform these tasks.
Using ActiveX controls in SharePoint Server
Some functionality in SharePoint Server requires ActiveX controls. This produces limitations on browsers which do not support ActiveX. Currently only 32-bit versions of Internet Explorer support this functionality. In SharePoint Server 2016, all other supported browsers, including Microsoft Edge and the Immersive mode of Internet Explorer 10 have the following limitations.
For SharePoint Server 2016 and 2019, browsers other than Internet Explorer 11 have the following limitations.
