Introduction By default, every Microsoft Teams channel includes a Files tab, which provides access to SharePoint and OneDrive storage. While you can’t rename the Files tab (see my post here), you can control its visibility using Teams Files Channel Policy settings. In this post, I’ll demonstrate how to use PowerShell to hide or show the Files tab in Teams channels by configuring the SPChannelFilesTab and NativeFileEntryPoints policy settings.
