Exchange Server Email Signature Setup: Go-Live Checklist

Validate an Exchange signature deployment before full rollout: config sign-off, pilot mailboxes, rules check, staged rollout, monitoring and rollback.

WiseStamp for IT › Exchange › Step 9 of 12 — Go-Live Checklist


What WiseStamp requires, and what we recommend beyond it: the product requirement to mark an integration live is a single test email from any active employee with an assigned signature. The pilot-and-rollout process below goes further on purpose; treat it as recommended IT acceptance practice rather than a product requirement.


Pre-go-live: configuration sign-off

  • ☐ Topology confirmed (off-prem / hybrid / on-prem). Pure on-prem is not supported — do not proceed past this checklist for pure on-prem.

  • ☐ Entra ID connected; expected employees imported (Identity & Employee Sync). (Employee sync is not supported for on-prem; no plan supports it.)

  • ☐ Synced fields verified against Entra ID.

  • ☐ Deployment configured:

  • ☐ (Hybrid mode) Both configured; duplicate-prevention confirmed.

  • ☐ (Platform/Enterprise) SSO tested if in scope (SSO (SAML)).

  • ☐ Signatures assigned (Primary Signature; groups; server-side rules as needed).

  • ☐ (Server-side) SPF verified; DKIM added and signing enabled; RTF = Never.


Stage 1 — Pilot group

Pick 5–10 users across supported environments: Outlook desktop (Win), Outlook for Mac, Outlook web, Outlook mobile, and — for server-side — at least one non-Outlook sender (mobile mail app or CRM).

Per pilot user:

  • ☐ Set Active in WiseStamp.

  • ☐ (Add-In) Restarted Outlook desktop / refreshed Outlook web.

  • ☐ New / Reply / Forward show expected signature behavior.

  • ☐ Correct rendering to internal and external recipients.

  • ☐ Images/logos load and sized correctly.

  • ☐ No duplicate signature (else check manual copy/paste signatures — Troubleshooting Reference).

  • ☐ (Server-side) Signature appears from a non-Outlook device.

  • ☐ (Server-side) Authentication shows SPF and dkim=pass.

  • ☐ Legible in dark mode.

Stage 2 — Rules & scoping check (if used)

  • ☐ Each server-side rule applies to the intended senders/email types/recipients.

  • ☐ Rule priority produces the intended result when multiple match.

  • ☐ Group-based assignment maps the right signature to the right group.


Stage 3 — Full rollout


Stage 4 — Post-go-live monitoring (1–2 weeks)

  • ☐ Triage "no signature" / "duplicate" tickets with Troubleshooting Reference.

  • ☐ (Server-side) Confirm mail flow healthy; no routing-induced delays/rejections.

  • ☐ New hires in Entra ID appear on the next daily sync; leavers removed.

  • ☐ Several admins retain Exchange admin center access.
