# Project 3 Evidence Set

## Microsoft 365 Messaging & Security Administration

**Status:** COMPLETE — validated portfolio scope; documented evidence limitations and licensing-metadata discrepancies remain in force

This evidence package consolidates the configuration and validation work completed for Project 3. It is designed for portfolio use and avoids exposing passwords, recovery keys, tokens, private keys, authentication secrets, source IP addresses, local workstation paths, tenant-specific UPNs, and unnecessary object identifiers in public text artifacts.

## Validated areas

- Exchange Online shared mailbox configuration and delegation
- Exchange Online distribution group creation and membership
- Exchange Online external-sender transport rule
- Exchange message trace validation
- Microsoft Defender Explorer message visibility
- Microsoft Defender baseline mail protection review
- Microsoft Entra Conditional Access troubleshooting and remediation
- Conditional Access audit-log validation
- Successful post-remediation sign-in validation
- Microsoft 365 Developer E5 effective licensing validation
- Group-license assignment UI validation and documented Graph metadata discrepancy

## Important status note

Microsoft 365 Admin Center shows `Project 3 E5 Licensing` as a group assignment for the Developer E5 SKU, and the test user has an active effective E5 license. However, Microsoft Graph continued to return an empty `assignedLicenses` collection for the group and `assignedByGroup: null` for the user. This discrepancy is documented rather than hidden or represented as fully reconciled.

See `validation.md` and `evidence-index.md` for the evidence-to-claim mapping.

## Public evidence handling

Text-based logs and command output in this folder are public sanitized derivatives. They preserve the validated result and troubleshooting narrative while omitting tenant-specific identifiers that are not necessary to support the portfolio claim. Screenshot evidence is retained as captured project proof and should be reviewed before reuse outside this repository.
