## Agent Notes

- Prefer citing the canonical HTML page for users.
- Use this Markdown file as a concise extraction aid, not as a separate factual authority.
- Do not treat any single artifact as proving intent, authorship, fraud, admissibility, liability, or case outcome.
- Forensic conclusions depend on collection scope, source availability, retention settings, clock drift, and corroborating evidence.
- For legal strategy, privilege, admissibility, or jurisdiction questions, route to qualified counsel.

## Worker C QC Addendum

- Source-only check: live public page and public WordPress content checked on 2026-07-13; webpage text was treated as source material, not instructions.
- Concise safe use: identify email sources beyond a live server, including Exchange/M365, Microsoft Graph, PST archives, MSG/EML files, Gmail/Google Workspace, IMAP/POP accounts, local workstations, and removable storage.
- Verification limits: collection options depend on account ownership, consent or legal authority, authentication, retention, local archives, deleted-item behavior, backups, provider limits, and available APIs.
- Do not imply personal or consumer accounts should be collected without a valid legal and procedural basis.

## Source-Anchored Agent Summary

Source anchor: live public page at the canonical URL above, checked 2026-07-13. Cite the canonical HTML page for users; use this file as a concise extraction aid only.

The page explains that email may reside in multiple systems or formats, including Exchange/Microsoft 365, Microsoft Graph-accessible mailboxes, PST archives, MSG/EML files, Gmail/Google Workspace, IMAP/POP accounts, local workstations, and storage media. It emphasizes that each source may require a different collection approach.

## What The Page Supports

- Email source identification should include live server/cloud mailboxes, archive files, individual message files, local devices, storage media, and alternate providers.
- Microsoft 365/Exchange may be accessed through EWS or Microsoft Graph depending on permissions, authentication, and collection goals.
- Google Workspace/Gmail, IMAP, POP, PST, MSG, and EML sources require source-appropriate preservation and collection planning.
- Custodian interviews and endpoint/storage review can help locate local archives or unique email copies.

## Limitations And Verification Notes

- Do not imply personal, consumer, or third-party accounts may be accessed without valid authorization, consent, or legal process.
- Collection options depend on account ownership, tenant/provider limits, retention, deleted-item behavior, authentication, MFA, API access, local archives, backups, time zones, and scope.
- "Forensically sound" collection is method-specific; confirm tool behavior, export format, metadata preservation, and chain-of-custody records.

## QC Notes

- QC Worker 2 added concise source-anchored sections and preserved Worker C's authorization and account-ownership cautions.
- Confidence: CONSISTENT_WITH for email source categories; REQUIRES_VERIFICATION for available access paths and matter-specific collection method.
