get-O365InactiveUsers

3.4

This script will generate a HTML file to list all inactive users and the last logon of users based on the audit log.
Inactive users will normally be collected using the users mailbox but external and users without a license don't have a mailbox.
We will be using the audit log to find successful and failed logons for internal users and page viewes for external users.
