CodeTwo Email Signatures 365 - How does it work?

How does the program work?

CodeTwo Email Signatures 365 is a cloud-based solution developed to help administrators centrally manage email signatures and disclaimers in Microsoft 365 (Office 365). The software offers an all-web experience, meaning that you can create and manage signature templates as well as signature rules that specify which users or user groups get access to individual signature templates from anywhere and on any device or platform (including Windows, Mac, mobile phones, tablets, and so on).

Signature modes

Signature modes control how signatures are added in your organization. The CodeTwo service can operate in the following modes: cloud (server-side), Outlook (client-side), or combo. Signature mode is first selected when you register your Microsoft 365 tenant to our service but can be later changed at any time.

Works with all email clients. A signature is added after an email is sent (but you can deploy the CodeTwo Outlook Web Add-in to preview a signature as you type an email in Outlook for Windows, Mac and Outlook on the web). Requires setup of Microsoft 365 connectors. Does not require deployment of the add-in.
