Britney Thompson Litigation Hold Verification

Date: 2026-05-07 Tenant: Cascades of Tucson (207fa277-e9d8-4eb7-ada1-1064d2221498) Context: HIPAA compliance requirement (§164.308(a)(3)(ii)(C) + §164.316(b)(2)) Requested by: Mike Swanson (responding to Howard's note from 2026-05-06)

Summary

Status: UNABLE TO VERIFY - App onboarding required

Attempted to verify Britney Thompson's mailbox litigation hold status but discovered the ComputerGuru Security Investigator app is not onboarded to the Cascades Tucson tenant. Exchange REST API calls return HTTP 401 Unauthorized.

User Confirmed

User found via Graph API:

Display Name: Britney Thompson
UPN: Britney.Thompson@cascadestucson.com
Mail: Britney.Thompson@cascadestucson.com

User account exists and is active.

Blocker: MSP App Not Onboarded

Issue: The ComputerGuru Security Investigator service principal (app ID bfbc12a4-f0dd-4e12-b06d-997e7271e10c) does not exist in the Cascades Tucson tenant.

Impact: Cannot execute Exchange REST API commands (Get-Mailbox, Get-InboxRule, etc.) required for:

Litigation hold verification
Mailbox forwarding checks
Inbox rule enumeration
Delegate permission audit

Required Actions:

Onboard Security Investigator app to Cascades tenant:
- Grant admin consent to the app
- Assign Exchange Administrator directory role to the service principal
- Verify token acquisition works for investigator-exo tier

Run litigation hold check after onboarding:

curl -X POST \
  -H "Authorization: Bearer $TOKEN" \
  -H "Content-Type: application/json" \
  "https://outlook.office365.com/adminapi/beta/207fa277-e9d8-4eb7-ada1-1064d2221498/InvokeCommand" \
  -d '{"CmdletInput":{"CmdletName":"Get-Mailbox","Parameters":{"Identity":"Britney.Thompson@cascadestucson.com"}}}' \
  | jq '.value[0] | {LitigationHoldEnabled, LitigationHoldDate, LitigationHoldOwner, InPlaceHolds}'

Document findings for HIPAA compliance record.

HIPAA Compliance Risk

From Howard's 2026-05-06 note:

We need to verify before Wave 1 caregiver rollout that her mailbox was either: (a) placed on Litigation Hold prior to conversion, or (b) is still convertible (i.e. not yet harvested) so we can still apply the hold.

If neither, we have a §164.308(a)(3)(ii)(C) + §164.316(b)(2) gap to document.

Current Status: Unknown - cannot verify until app is onboarded.

Regulatory Context:

§164.308(a)(3)(ii)(C): Termination procedures - requires retention of electronic PHI access records
§164.316(b)(2): Documentation retention - minimum 6 years from creation/last effective date

Risk if litigation hold was not applied:

If Britney Thompson's role involved PHI access, her mailbox may contain HIPAA-relevant communications
Without litigation hold, mailbox retention follows standard retention policies (may be insufficient for compliance)
Gap must be documented if hold was not applied and conversion already completed

Next Steps

Mike: Approve Security Investigator app onboarding to Cascades tenant

Howard (or Mike): Run onboarding script:

bash .claude/skills/remediation-tool/scripts/onboard-tenant.sh cascadestucson.com

Re-run this check after onboarding completes
Apply litigation hold if not already enabled:
- If enabled: Document date and duration
- If not enabled: Apply hold immediately if mailbox still exists
- If mailbox already converted/harvested: Document the gap for HIPAA compliance record
