Cascades of Tucson — Chris Knight accounting mailbox delegation

Session Summary

Chris Knight needed access to the Cascades accounting email as an attached account in Outlook — able to read and to send. Routed the request through the remediation-tool skill against the Cascades M365 tenant (cascadestucson.com, 207fa277-e9d8-4eb7-ada1-1064d2221498).

The opening consent audit graded the tenant RED, reporting "app NOT consented (token mint failed)" for all four app tiers. That was a false negative. The wiki recorded that the Exchange Operator app had worked against this tenant as recently as 2026-06-12 (the grievances@/Surveys@ shared-mailbox delegations), which contradicted the audit. Testing the token mint directly surfaced the real fault: get-token.sh resolves the vault from ~/.claude/identity.json, but this machine's identity and vault_path (D:/vault) live in the repo at .claude/identity.json. With VAULT_ROOT_ENV=D:/vault the exchange-op token minted immediately. The tenant was fully consented the whole time.

Read-only recon via the EXO REST InvokeCommand endpoint identified accounting@cascadestucson.com as a SharedMailbox ("Accounting Dept.", account disabled — normal for shared) and confirmed accountingassistant@ is a distinct UserMailbox, not a delegate. The existing delegates — Lauren Hasselman, Ashley Jensen, Zachary Nelson — each held FullAccess + SendAs. The wiki independently records Chris Knight as "same access tier as Lauren Hasselman," so the grant pattern was unambiguous.

After explicit user confirmation, applied Add-MailboxPermission (FullAccess, InheritanceType All, AutoMapping $true) and Add-RecipientPermission (SendAs) via the exchange-op tier. Both returned OK. The first verification read-back showed FullAccess but not SendAs — Exchange replication lag, not a failed write. A re-read confirmed Chris on the SendAs list, and the trustee GUID returned by the write (a1f1bb9e-0cee-4a49-8397-189e6137d680) matched his ExternalDirectoryObjectId.

Closed out by updating wiki/clients/cascades-tucson.md with a new accounting@ delegation record (delegates, grant pattern, replication gotcha) and a note on Chris's staff line. Logged two errorlog entries for the path-drift defects found along the way.

Key Decisions

  • Did not trust the RED consent audit. The wiki's 2026-06-12 record of a successful Exchange Operator write against this tenant contradicted it. Verifying the token mint directly was cheaper than acting on the audit — and acting on it would have meant emailing the client an admin-consent link they did not need.
  • Granted SendAs, not SendOnBehalf. All three existing delegates hold SendAs; SendOnBehalf would render as "Chris Knight on behalf of Accounting Dept." to recipients and break parity with the rest of the accounting staff.
  • AutoMapping $true was the specific mechanism the request required — "attached email account" means the mailbox self-attaches to the Outlook profile via AutoDiscover, rather than the user hand-adding it.
  • Re-read before declaring the SendAs write failed. The write returned a trustee GUID; resolving that GUID against Get-Mailbox proved the grant landed and the read was stale.
  • Skipped a full /wiki-lint pass. Two bullet edits to one existing article introduced no [[wikilinks]]. Ran the applicable checks (link integrity, article structure) instead of a whole-wiki scan.

Problems Encountered

  • consent-audit.sh reported a false RED "app NOT consented" for all four tiers. Root cause was a local vault-path lookup failure, not tenant consent. The script conflates "could not read the vault" with "tenant has not consented." Resolved with VAULT_ROOT_ENV=D:/vault. Logged to errorlog.md; the script should fail loud on a vault-path error rather than downgrading it to a consent finding. This is the dangerous one — the false negative points directly at sending a client an unnecessary consent link.
  • get-token.sh and peers read ~/.claude/identity.json, but the authoritative identity (with vault_path) is the repo's .claude/identity.json. Same path-drift family.
  • .claude/commands/wiki-lint.md hardcodes cd D:/claudetools, but claudetools_root on this machine is C:/claudetools. Logged as --friction.
  • Post-write Get-RecipientPermission did not show the new SendAs trustee. Exchange replication lag across replicas. Re-read confirmed. Recorded in the wiki so the next delegate-add does not misread this as a failure.

Configuration Changes

File Change
wiki/clients/cascades-tucson.md Added accounting@ delegation record + grant pattern + replication gotcha (line ~291); appended accounting-mailbox note to Chris Knight's staff line (line ~214)
errorlog.md 2 entries: remediation-tool/consent-audit.sh (false RED), wiki-lint (hardcoded path, --friction)

M365 tenant changes (Cascades): two permission grants on accounting@cascadestucson.com — see Commands below. No code changes.

None discovered, created, or rotated this session.

  • Vault accessed read-only for app credentials: msp-tools/computerguru-exchange-operator.sops.yaml, msp-tools/computerguru-security-investigator.sops.yaml.
  • Auth path was certificate-based ([INFO] auth=cert), client_credentials flow.
  • Vault root on this machine: D:/vault (from repo .claude/identity.jsonvault_path).

Commands & Outputs

Token mint — the fix for the false RED:

# FAILS: scripts look at ~/.claude/identity.json
bash scripts/get-token.sh cascadestucson.com exchange-op
# ERROR: vault_path not set in /c/Users/Howard/.claude/identity.json and VAULT_ROOT_ENV env var not set

# WORKS:
VAULT_ROOT_ENV=D:/vault bash scripts/get-token.sh cascadestucson.com exchange-op
# [INFO] auth=cert
# eyJ0eXAiOiJKV1QiLCJub25jZSI6...

The two grants (exchange-op token, POST to InvokeCommand):

{"CmdletInput":{"CmdletName":"Add-MailboxPermission","Parameters":{
  "Identity":"accounting@cascadestucson.com",
  "User":"Chris.Knight@cascadestucson.com",
  "AccessRights":"FullAccess","InheritanceType":"All","AutoMapping":true}}}
{"CmdletInput":{"CmdletName":"Add-RecipientPermission","Parameters":{
  "Identity":"accounting@cascadestucson.com",
  "Trustee":"Chris.Knight@cascadestucson.com",
  "AccessRights":"SendAs","Confirm":false}}}

Outputs:

[OK] S-1-5-21-3975168698-2031163149-733277609-62630518 -> FullAccess (Deny=False)
[OK] a1f1bb9e-0cee-4a49-8397-189e6137d680 -> SendAs (Allow)

Verification (note the lag — first SendAs read omitted Chris, second included him):

{"CmdletInput":{"CmdletName":"Get-MailboxPermission","Parameters":{"Identity":"accounting@cascadestucson.com"}}}
{"CmdletInput":{"CmdletName":"Get-RecipientPermission","Parameters":{"Identity":"accounting@cascadestucson.com"}}}

Errorlog:

bash .claude/scripts/log-skill-error.sh "remediation-tool/consent-audit.sh" "<false RED>" \
  --context "tenant=cascadestucson.com machine=HOWARD-HOME"
bash .claude/scripts/log-skill-error.sh "wiki-lint" "<hardcoded D:/claudetools>" \
  --friction --context "ref=identity.json/claudetools_root machine=HOWARD-HOME"

Pending / Incomplete Tasks

  • Chris's Outlook: AutoMapping attaches via AutoDiscover refresh — typically a few hours, reliably after an Outlook restart. SendAs can take ~60 min to replicate before sending from accounting@ stops bouncing. Not yet confirmed on his endpoint (DESKTOP-N5G1ROO, GuruRMM agent 205025ee-2676-4498-8a27-e88562a6f69a). Worth a spot-check if he reports the mailbox missing.
  • consent-audit.sh fix (real bug, unfixed): must distinguish "vault unreadable" from "tenant not consented." Currently a local config fault renders as a client-facing consent gap. Highest-value of the three.
  • get-token.sh + sibling scripts: resolve identity from repo .claude/identity.json (honoring claudetools_root), not ~/.claude/identity.json. Until fixed, every remediation-tool invocation on this machine needs VAULT_ROOT_ENV=D:/vault.
  • .claude/commands/wiki-lint.md: replace hardcoded cd D:/claudetools.
  • No Syncro ticket was opened or referenced for this change. If it should be billed or tracked, it needs one.
  • No /wiki-compile run — wiki was hand-edited directly.
