Script Highlights:
|
|
~~~~~~~~~~~~~~~~~
|
|
1. The script exports 2 different reports:
|
|
-Detailed report: Teams and their guest user details
|
|
-Summary report: Teams and their guest users count
|
|
2. Automatically installs the Microsoft Teams PowerShell module (if not installed already) upon your confirmation.
|
|
3. Exports the report result to CSV.
|
|
4. The script can be executed with an MFA enabled account too.
|
|
5. It can be executed with certificate-based authentication (CBA) too.
|
|
6. The script is schedular-friendly.
