Name: Find inbox rules with external email forwarding
Description: This script Finds all inbox rules that forwards emails externally in Office 365 using PowerShell
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.
3.Automatically installs the EXO V2 module (if not installed already) upon your confirmation.
4.Helps to filter-out forwarding rules that forwards emails to external users by excluding guest accounts.
5.The script is scheduler – friendly. i.e., credentials can be passed as parameters rather than being saved inside the script.
6.Exports the report result to a CSV file.
