From 7fc29a7c5fcc3a3753c37f2d8bb71fd86f9ac099 Mon Sep 17 00:00:00 2001 From: Mike Swanson Date: Mon, 8 Jun 2026 20:07:28 -0700 Subject: [PATCH] fix(remediation): close the recurring Exchange-Admin-role gap fleet-wide MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit EXO email-cleanup tasks (Search-UnifiedAuditLog, Get-MessageTrace, inbox rules) kept 401/403-ing per tenant because the Exchange Operator SP was missing the Exchange Admin directory role — admin consent grants Exchange.ManageAsApp but never the directory role. onboard-tenant.sh assigns it, but tenants consented before that step / by hand never got it, and nothing audited for it. Hence the recurring 'next onboarding will fix it' (false for already-onboarded tenants). - NEW assign-exchange-role.sh: idempotent role assignment via the authoritative roleManagement/directory/roleAssignments API (the legacy directoryRoles/members list reads back unreliably). + --verify/--dry-run. - Backfilled the whole fleet (--all): 13 stragglers ASSIGNED, 12 already OK, 20 skipped (tenant-admin not consented), 0 errors. Safe Site included. - Standing audit documented (assign-exchange-role.sh --all --verify) + memory so no future session repeats the empty promise. - Adds wiki/clients/safesite.md (tenant + 4-source endpoint inventory + investigation).

Mike (2026-06-08) called this out as recurring disappointment. The real cause and the permanent fix: + +**Root cause:** app-only EXO management needs the **ComputerGuru Exchange Operator** SP (`b43e7342-5b4b-492f-890f-bb5a4f7f40e9`) to hold BOTH `Exchange.ManageAsApp` (granted by admin consent) AND the Entra **Exchange Administrator** directory role (`29232cdf-9323-42fd-ade2-1d097af3e4de`). Admin consent grants the API permission but NEVER the directory role. `onboard-tenant.sh` Step 5 DOES assign it (via the reliable `roleManagement/directory/roleAssignments` API) — but tenants consented **before that step existed, or consented by hand**, never got it, and nothing audited for the gap. So the recurrence was old/manual stragglers, not an onboarding bug. + +**The fix (do this, don't promise):** +- `bash .claude/skills/remediation-tool/scripts/assign-exchange-role.sh [--verify|--dry-run]` — assigns the role to the Exchange Operator SP. Idempotent. `--all` backfills every tenant in `references/tenants.md`; tenants where tenant-admin isn't consented are SKIPped. **Backfilled fleet-wide 2026-06-08** (~10 stragglers fixed). +- **Standing audit:** run `assign-exchange-role.sh --all --verify` periodically — any `WOULD assign` is a tenant that will fail the next email-cleanup task; fix it proactively, not mid-incident. +- **Gotcha:** the legacy `directoryRoles/{id}/members` LIST endpoint reads back unreliably (replication lag) — it falsely showed Safe Site unassigned right after a successful write. Always verify role membership via `roleManagement/directory/roleAssignments?$filter=principalId eq ''`, not the members list. +- **Propagation:** after assigning, EXO app-only access takes **15–60 min** to start working (EXO-side replication) — a 403 immediately after the grant is normal, not a failure. + +**Why:** stop telling Mike "next time it'll be automatic" for a tenant that's already onboarded — that promise is structurally false. The durable answer is the backfill + the standing `--verify` audit.
