Rednour Law — MSP Suite Onboarding + Account Rename (emma@ → carla@)

Date: 2026-05-31 (UTC) Tenant: rednourlaw.com (4a4ca18a-f516-478b-99da-2e0722c5dc18) Operator: Mike Swanson (GURU-KALI) Apps used: ComputerGuru Tenant Admin, Exchange Operator, User Manager

Action Summary

Two operations chained:

1. Bootstrapped the full ComputerGuru MSP app suite for the rednourlaw.com tenant (Tenant Admin consent followed by onboard-tenant.sh). Prior state: only Tenant Admin was consentable; no Exchange/User roles assigned. Triggered by HTTP 403 on Get-Mailbox during the rename attempt — the Exchange Operator SP existed but lacked Exchange Administrator role.
2. Renamed emma@rednourlaw.com → carla@rednourlaw.com (Carla Skinner) in a three-call sequence: Set-Mailbox for EmailAddresses, Graph PATCH /users/{id} for identity fields, POST /revokeSignInSessions to invalidate any active token.

Onboarding Result

SP	App ID	Status	Roles assigned
Tenant Admin	709e6eed-0711-4875-9c44-2d3518c47063	Consented manually	Conditional Access Administrator
Security Investigator	bfbc12a4-f0dd-4e12-b06d-997e7271e10c	Programmatic	Exchange Administrator
Exchange Operator	b43e7342-5b4b-492f-890f-bb5a4f7f40e9	Programmatic	Exchange Administrator
User Manager	64fac46b-8b44-41ad-93ee-7da03927576c	Programmatic	User Administrator, Authentication Administrator
Defender Add-on	dbf8ad1a-54f4-4bb8-8a9e-ea5b9634635b	Programmatic	(none — no MDE license in this tenant)

Defender Add-on consent succeeded but the tenant has no MDE license, so calling Defender ATP endpoints will return AADSTS650052. Skip the defender tier for this tenant.

Exchange Administrator role on the Exchange Operator SP propagated within ~60s (Get-Mailbox switched from 403 to 200 on the second try).

User Rename — Before

id:                93074d1a-6db2-4794-8f7d-c84a619e4494
UPN:               emma@rednourlaw.com
displayName:       Emma - Rednour Law
mail:              emma@rednourlaw.com
mailNickname:      dgarcia
givenName:         Emma
surname:           (null)
PrimarySmtpAddress: emma@rednourlaw.com
EmailAddresses:
  SIP:emma@rednourlaw.com
  SMTP:emma@rednourlaw.com               (primary)
  smtp:dgarcia@rednourlaw.com            (legacy)
  smtp:alee@rednourlaw.com               (legacy)
  smtp:dgarcia@rednourlaw.onmicrosoft.com (routing)
  SPO:SPO_f390956f-...@SPO_<tenant>      (SharePoint auto)
EmailAddressPolicyEnabled: False
accountEnabled: true

The mailNickname dgarcia and the two legacy aliases indicate this mailbox was previously inherited from earlier employees Garcia → Emma. The chain continues with the rename to Carla.

User Rename — After

id:                93074d1a-6db2-4794-8f7d-c84a619e4494  (unchanged)
UPN:               carla@rednourlaw.com
displayName:       Carla Skinner
mail:              carla@rednourlaw.com
mailNickname:      carla
givenName:         Carla
surname:           Skinner
PrimarySmtpAddress: carla@rednourlaw.com
EmailAddresses:
  SIP:emma@rednourlaw.com                (will auto-regen to carla@ on next sync)
  SMTP:carla@rednourlaw.com              (new primary)
  smtp:emma@rednourlaw.com               (alias — Emma's old mail still routes here)
  smtp:dgarcia@rednourlaw.com            (legacy — kept per operator)
  smtp:alee@rednourlaw.com               (legacy — kept per operator)
  smtp:dgarcia@rednourlaw.onmicrosoft.com (existing routing — Exchange chose not to swap to carla@)
  SPO:SPO_f390956f-...@SPO_<tenant>      (unchanged)
accountEnabled: true

Sign-in Session Revocation

POST /users/93074d1a-.../revokeSignInSessions returned 200 {"value": true}. All refresh tokens and active sessions under the previous UPN are invalidated; next access requires re-authentication as carla@rednourlaw.com.

Decisions Made During Execution

• Kept both legacy aliases (dgarcia@, alee@) — operator's explicit choice. If those external addresses are confirmed dormant in the future, revisit removing them.
• No password reset — operator confirmed this is a name change, not a personnel handoff; Carla already knows the password.
• Sessions revoked unconditionally — standard practice after any UPN change.
• SP role/consent strategy — bootstrapped the full suite (not just Exchange Operator) since onboarding was already incomplete. Future operations against this tenant now have the full toolset available.

Two Cosmetic Items That Did Not Apply

1. SIP:emma@rednourlaw.com persisted instead of updating to SIP:carla@rednourlaw.com. Exchange auto-derives SIP from UPN — should self-heal on next mail-flow event or Teams sign-in.
2. smtp:carla@rednourlaw.onmicrosoft.com was not added; Exchange kept the existing smtp:dgarcia@rednourlaw.onmicrosoft.com routing entry. Tenant routing through *.onmicrosoft.com still resolves to the right mailbox regardless of the local-part, so mail flow is unaffected.

Neither is blocking. If they bother you, a single follow-up Set-Mailbox call can rewrite EmailAddresses with the cleaned list.

Raw Artifacts

Preserved under /tmp/remediation-tool/4a4ca18a-f516-478b-99da-2e0722c5dc18/rednour-rename/:

• get-mailbox-before.json — pre-rename state
• set-mailbox-resp.json — Set-Mailbox response (empty value collection + warnings array — normal)
• get-mailbox-after.json — first verify (stale due to replication)
• get-mailbox-after2.json, get-mailbox-final.json — converged verifies
