How to change link of "Open in SharePoint" of file tab?
How to change link of "Open in SharePoint" of file tab, if I want to link other SharePoint site?
Is it possible to change link of default SharePoint site after I make new team site, not to add new tab ? I want to use already exiting SharePoint site as default SharePoint site, but the site owner is not me. If I create option "create a team from an existing Office 365 group", it's only allow my SharePoint site.
