Register and Configure Tenant

Once you sign up with Sigsync, the next step is to register your Microsoft 365 tenant. This allows you to centrally manage email signatures across your organization, ensuring that all outgoing emails are signed consistently and securely. Tenant registration requires a Global Admin account, which grants permission to access user details for applying signatures. Your credentials are never shared — authentication is handled securely through Microsoft’s sign-in using Azure OAuth 2.0.

Steps to Register and Configure Tenant in Sigsync:

• Login to Sigsync dashboard
• Navigate to ‘Manage Signatures’ > ‘Register & Manage Tenants’ tabs

  

• Click the ‘Add Tenant Now’ button.

  

• Click ‘Continue’ to proceed

  

• Sigsync is a secure service that follows Microsoft’s recommended flow for Office 365 email signatures and security. It uses Azure OAuth 2.0 authentication to connect with your Office 365 tenant through Microsoft’s official sign-in process. A one-time authentication using a Global Admin account is mandatory to proceed.

  

• Accept the required permissions for the Sigsync Office 365 Email Signature Service to access user details and add it to email signatures. Only a Global Admin account in Microsoft 365 can grant these permissions.

  

Scope & region

• Select the geolocation for the Sigsync Azure server. This location will be used to apply signatures (in mixed or server-side mode) and to store your settings. It is recommended to choose the same region as your Microsoft 365 tenant, or the nearest available option.

  

  Note: Choose your region carefully, as it cannot be changed later without deregistering your tenant, which will also cancel your subscription. If you ever need to switch regions, reach out to Sigsync support.

• Adding Tenant may take a couple of minutes to complete.

  

• Now the Tenant is added successfully. Click the ‘Continue’ button to proceed with the signature configuration

  

Signature Configuration

Sigsync offers two modes for applying email signatures, giving organizations flexibility to choose the setup that best matches their requirements. The default and recommended option is Centralized Mode, which offers centralized management and ensures consistent signatures across all email clients and devices. For organizations that rely exclusively on Outlook and prefer signatures to be applied locally, Sigsync also offers Client Mode, which provides maximum user control while maintaining security.

Centralized Mode (Recommended)

A complete solution for centralized email-signature management.

• Compatible with all email clients and devices
• Signatures are visible during email composition and editing
• Option to enforce non-editable signatures, ensuring they are automatically applied to emails when the server side signature rules are met
• Supports all major platforms - Windows, macOS, Linux, iOS, Android, and more.
• Ideal for organizations with users across multiple clients (e.g., Outlook, OWA, etc.)
• Administrators control how and when signatures are applied
• Users can preview, switch to alternate signatures, or choose to configure server-side signatures

Client Mode (Outlook) :

Signatures are applied locally within Outlook, ensuring maximum user control and security.

• Works exclusively with Outlook (Windows, Web, Mac, iOS, Android)
• Signatures are inserted in real-time while composing emails. Users can choose and insert preferred signatures Outlook add-in panel
• Requires deployment of the Sigsync Signature for Outlook add-in
• Emails are sent directly from Outlook, without being routed through Sigsync
• Best suited for organizations where all users rely on Outlook and prioritize strict security and control
• Users can manually select alternative signatures
• Signatures remain visible during composition, with an option to exclude them if required

• Click ‘Authorize’ to proceed with setting up connectors automatically.

  

Set Senders

• The Set Sender Wizard helps you decide which users or groups should have signatures applied. You can choose from the following options:
  • Enable email signatures for all users/groups
    This option lets you apply signatures to every user in your Microsoft 365 tenant.

    

  • Enable email signatures for specific groups
    This option lets you apply only to the members of your Office 365 Azure Active Directory groups (Example: ‘Sales’, ‘HR’, or ‘Support’ etc.)
• Click ‘Choose Groups’

  

• Select the required group and click ‘Ok’ to proceed
• The selected AD groups will be displayed. To remove a group from the list, click the ‘x’ icon in its corresponding row. Click ‘Continue’.

  

• Click the ‘Configure’ button to proceed with the Sigsync signature configuration

  

• Sigsync connectors and transport rules configuration takes a couple of minutes to complete.
• Click 'Continue' to deploy the Sigsync Signature Add-in for Outlook.

  

• Add-in deployment takes a couple of minutes to complete
• Once the add-in is successfully deployed, Microsoft may take up to 72 hours to propagate it to users’ Outlook.
