Name: Get all enterprise apps and their owners
|
||||
Version: 1.0
|
||||
Website: o365reports.com
|
||||
|
||||
|
||||
Script Highlights:
|
||||
~~~~~~~~~~~~~~~~~
|
||||
1. The script exports all enterprise apps along with its owners in Microsoft Entra.
|
||||
2. Generates report for sign-in enabled applications alone.
|
||||
3. Exports report for sign-in disabled applications only.
|
||||
4. Filters applications that are hidden from all users except assigned users.
|
||||
5. Provides the list of applications that are visible to all users in the organization.
|
||||
6. Lists applications that are accessible to all users in the organization.
|
||||
7. Identifies applications that can be accessed only by assigned users.
|
||||
8. Fetches the list of ownerless applications in Microsoft Entra.
|
||||
9. Assists in filtering home tenant applications only.
|
||||
10. Exports applications from external tenants only.
|
||||
11. The script uses MS Graph PowerShell and installs MS Graph PowerShell SDK (if not installed already) upon your confirmation.
|
||||
12. Exports the report result to CSV.
|
||||
13. The script can be executed with an MFA enabled account too.
|
||||
14. It can be executed with certificate-based authentication (CBA) too.
|
||||
15. The script is schedular-friendly.

||||
