OneDrive for Business can be configured so that it notifies users when certain activities pertaining to sharing are configured or used, as shown in the following screenshot:

You can also configure these settings via PowerShell using Set-SPOTenant.

The following Boolean (true/false) parameters govern the OneDrive notification settings (in the same order they are displayed in the preceding screenshot):

• NotificationsInOneDriveForBusinessEnabled: Enables or disables push notifications for OneDrive sharing
• NotifyOwnersWhenItemsReshared: Enables or disables emails from being sent to OneDrive for Business owners when sharing recipients re-share items to additional external parties

• NotifyOwnersWhenInvitationsAccepted: Enables or disables emails from being sent to OneDrive for Business owners when an invitation to an external user has been accepted
• OwnerAnonymousNotification: Enables or disables emails from being sent to OneDrive for Business owners when an anonymous access link is created or changed

An example of this is as follows:

Set-SPOTenant -NotificationsInOneDriveForBusinessEnabled $true -NotifyOwnersWhenItemsReshared $true -NotifyOwnersWhenInvitationsAccepted $true -OwnerAnonymousNotification $true

Now that you've configured some of the basic OneDrive settings, let's look at managing permissions and delegation.
