Name: Remove Direct Licenses for Group-Licensed Users Using PowerShell
|
||||
Version: 1.0
|
||||
website: o365reports.com
|
||||
|
||||
Script Highlights:
|
||||
~~~~~~~~~~~~~~~~~
|
||||
|
||||
1. This script generates reports on users with overlapping direct & group-based license assignments.
|
||||
2. The script removes direct assigned license(s) if the same license inherited via groups too.
|
||||
3. This script installs MS Graph PowerShell SDK (if not installed already) upon your confirmation.
|
||||
4. The script can be executed with an MFA-enabled account too.
|
||||
5. The script is schedular-friendly.
|
||||
6. It can be executed with certificate-based authentication (CBA) too.
|
||||

||||
