default share dialog on OD4B doesn't allow entering "everyone except external users"
When you click on share in OD4B, the dialog only allows getting links that work for everyone in the organization. But it doesn't allow you to enter "everyone except external users" when you want to share with everyone in teh company. The problem is that sometimes you want to change the permissions on the document so that everyone in the organization has access to it, but you don't want to send an email. There is currently no way to do that through the default share dialog.
you can do that through the details pane which allows you to enter "everyone except external users". But the experience should be the same. most users cannot find the hidden options under the details pane.
