How it works

Take email signatures off IT's plate

Connect SignSyncer to Exchange in minutes

Grant permissions via Entra ID or on-prem Active Directory
Map directory fields: name, title, department, phone, photo
Deploy server-side via journal connector or transport rule
Push the Outlook Add-In via MDM, GPO, or admin center

Built with enterprise security practices in mind

SSO via Okta, Entra ID, or OneLogin
Role-based access scopes each admin to their function
Server-side routing reads and stores zero email content
TLS encrypts all traffic in transit

Preparations for deployment

Active Directory or Entra ID for signature assignment
Exchange admin or Global Admin role for server-side setup
Outlook 2016 or later, on Windows or Mac, for the Add-In
No MX record changes or third-party mail routing required

FAQ

Exchange signature questions

Software that centrally deploys, updates, and governs email signatures across Exchange environments — syncing from Active Directory, enforcing disclaimers, and staying consistent across every device.

Yes — on-prem Exchange Server (2010–2019), Exchange Online within Microsoft 365, and hybrid environments. Server-side deployment guarantees coverage regardless of where users are.

Transport rules don't show in Sent Items, leave blank lines for empty attributes, don't support inline images, and are IT-only. SignSyncer solves all of these.

No. Server-side deployment uses a journal or transport rule connector within your existing Exchange infrastructure — no email traffic is rerouted through third-party servers.

SignSyncer archives or removes the signature automatically when the employee is deprovisioned in Active Directory or Entra ID — no manual cleanup needed.
