Name: Export Office 365 User Activity Report to CSV using PowerShell
Version: 2.0
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.Allows you to generate a user activity report for a custom period.
5.Automatically installs the EXO V2 module (if not installed already) upon your confirmation.
6.The script is scheduler friendly. I.e., Credential can be passed as a parameter instead of saving inside the script.
