+Name:           Track Offboarded User Activities in Microsoft 365 using PowerShell 
+Version:        1.0
+website:        o365reports.com
+
+Script Highlights:
+~~~~~~~~~~~~~~~~~
+1.The script uses modern authentication to connect to Exchange Online.  
+2.The script can be executed with MFA enabled account too.  
+3.Exports report results to CSV file.  
+4.The script exports audit log for 180 days by default.
+5.Allows you to keep audit log report for a custom period.  
+6.Automatically installs the EXO module (if not installed already) upon your confirmation. 
+7.The script is scheduler friendly. I.e., Credential can be passed as a parameter instead of saving inside the script. 
+8.The script supports Certificate-based authentication (CBA).
