 If you need to remove subscribers, you can choose as many as you want to remove by selecting the check mark next to the user or users, and then clicking Delete. You can also use Shift-Select to remove a selection of subscribers by clicking the check mark for the first user, then selecting the Shift key on your keyboard, and then selecting the last user in a list. Then click Delete to remove the subscribers. You can delete all the users by clicking the check mark at the top of the list to select everyone, and then click Delete. Subscribers added using Azure Active Directory groups will need to be removed from the group in Azure AD and can't be removed directly in the Visual Studio Subscriptions Administration portal.
