Server Mode Signatures

How Sigsync Server Mode Signatures Work

Sigsync Server Mode is a cloud-based service that uses a secure TLS connection with Microsoft 365 servers to process emails and apply signatures. When enabled, connectors and rules are automatically created in your Exchange Online environment, ensuring seamless routing and processing.

Here’s how the process works:

• You send an email from your Microsoft 365 account.
• Microsoft 365 applies Sigsync routing rules to the outgoing email. If the conditions match, the email is securely forwarded to Sigsync using the Outbound Connector via TLS.
• Sigsync receives the email, applies the configured signature rules (signatures, disclaimers, banners, etc.), and processes the message.
• The email is returned to Microsoft 365 through the Inbound Connector over TLS.
• Finally, Microsoft 365 delivers the email to the recipient, now stamped with the appropriate Sigsync signature.

This server-side model ensures centralized control, compliance, and consistent branding, without requiring users to configure signatures locally.

Steps to Set Up Server Mode Signatures

Step 1: Login to the Sigsync Dashboard

If you’re new, create a Sigsync account or sign in directly with your Microsoft account. The dashboard will automatically guide you through the configuration process.

Step 2: Register Tenant and Configure Signatures

Use your Office 365 Global Admin account to register the tenant with Sigsync. During registration, the wizard automatically configures the required inbound/outbound connectors and transport rules in Exchange Online. You only need to follow the wizard instructions.

Step 3: Create Signature Templates

Easily create email signature templates using the Sigsync signature editor. Add details from Azure Active Directory, such as name, job title, photo, and company information. You can also import your own HTML code or choose from a gallery of ready-made templates, and start from scratch.

Step 4: Set Signature Rules

Set signature rules to control when and to whom email signatures are applied. You can create rules based on senders, recipients, specific keywords, or Active Directory groups, ensuring the correct signature is added to every outgoing email.

Step 5: Add SPF Record to Your Domain

Include the Sigsync Azure Service in your domain’s SPF (Sender Policy Framework) TXT record to ensure emails pass security checks and are not flagged as spam, junk, spoofed, or phishing by Exchange Online Protection (EOP)
