Supported platforms and requirements

Sigsync Email Signatures for Office 365 is a centralized, web-based solution that does not require any additional components to be installed in your environment. It is platform independent and can be accessed from a browser on any device, including Windows desktop, Android phones, iPhones, iMacs, and Linux.

Below is a list of system requirements and required permissions for configuring and managing email signatures using Sigsync.

Sigsync Dashboard

  • A modern and latest web browser such as Google Chrome, Firefox, Opera, Safari or Microsoft Edge to access the Sigsync dashboard seamlessly.
  • Microsoft 365 (Office 365) Global admin rights required to register the Office 365 tenant and configure signatures. Sigsync employs Microsoft OAuth 2.0 and TLS encryption for authenticating your credentials. During the login, you will be directed to Microsoft's sign-in page for authentication. Your Office 365 login details are neither stored on Sigsync nor on any third-party servers, and your emails are not accessed by anyone.
  • A Microsoft 365 (Office 365) plan that includes Exchange online (Access to Exchange Transport Rules and Connectors needed; Sigsync supports Microsoft F1 and Kiosk plans as well).
  • Sigsync also supports Microsoft 365 trial subscriptions. With the Microsoft 365 trial subscription, you can register the tenant with Sigsync and test client-side signatures.

Note
Although the Sigsync Signatures Add-in for Outlook can be used with shared mailboxes, full support may not be available on Outlook Mac. This is because shared mailboxes are not yet officially supported on Microsoft's Office Add-in platform.
Sigsync requires Microsoft 365 global admin rights (required for centralized deployment of the Sigsync Signatures Add-in only).
