I also tried this one https://chrome.google.com/webstore/detail/infinity-new-tab-producti/dbfmnekepjoapopniengjbcpnbljalfg, last update Nov 2020. It didn't do anything either and 'Options' menu is greyed out :(. Source: about 3 years ago
I can't think of a reason why this is -security wise- a reason to stuck to only the companies' Office 365-splash page as everyones default startpage. My gut feeling says that enabling a 2nd tab (with a startpage I can set) is not very different to me opening a 2nd tab myself and starting my own prefered startpage (symbaloo.com). But that's probably my simplistic way of thinking. Source: over 2 years ago
