SharePoint does not require IE (which is being removed completely next year) nor Edge. It runs well on any chromium-based browsers including Edge, Chrome and Brave. The system requirements for SharePoint are provided here.
Does sharepoint only work in IE
I'm trying to get a functioning information center working and we don't really use MS products (except 365/teams/outlook). I just want to make sure I should not use Sharepoint if it's going to require an entire agency to download an app they wouldn't use and probably don't want to use.
