-Name:           Export Office 365 user last logon time report
-Description:    This script exports Office 365 users' last logon time CSV
-Version:        3.0
+Name:           Export Microsoft 365 users' last logon time report using PowerShell
+Version: 5.0
+Last updated on: July, 2023
 website:        o365reports.com
-Script by:      O365Reports Team
-For detailed Script execution: https://o365reports.com/2019/03/07/export-office-365-users-last-logon-time-csv/
+
+Script Highlights:
+~~~~~~~~~~~~~~~~~
+#. Single script allows you to generate 10+ different last login reports.
+#. The script can be executed with MFA enabled account too.
+#. The script supports Certificate-based authentication (CBA).
+#. Allows you get last login time report for list of users through import CSV.
+#. You can generate report based on inactive days.
+#. Result can be filtered based on user / all mailbox type.
+#. Result can be filtered to lists never logged in mailbox alone.
+#. Generate report for sign-in enabled users alone.
+#. Supports filtering licensed users alone.
+#. Gets login time report for admins alone
+#. Export results to CSV file.
+#. The assigned licenses column will show you the user-friendly-name like ‘Office 365 Enterprise E3’ rather than ‘ENTERPRISEPACK’.
+#. Automatically installs Exchange Online PowerShell (to retrieve last logon time) and MS Graph PowerShell (to get license and admin roles) modules upon your confirmation.
