CodeTwo Outlook Add-ins overview
CodeTwo Email Signatures 365 lets you add signatures in the cloud (server-side), after emails are sent, directly in Outlook (client-side), as users compose their emails, or both. CodeTwo Outlook signatures are added by a dedicated add-in that can be deployed organization-wide. There are two add-ins that you can use:
- Modern CodeTwo Signatures Web Add-in for Outlook & OWA that works with Outlook for Windows, Outlook for Mac and Outlook on the web (OWA). This modern Web Add-in offers better experience and more capabilities. It can also be used to preview cloud signatures
- Legacy CodeTwo Signatures Add-in for Outlook (COM Add-in) that works with Outlook for Windows only.
You can only use either of the add-ins, so deploy the one that best matches your preferences. See the table below for a quick comparison of the CodeTwo Outlook add-ins.

Modern Web Add-in deployment
See our video tutorial to learn how to centrally deploy the CodeTwo Signatures Web Add-in for Outlook to users in your organization or use the links below for instructions:
- Microsoft AppSource (the easiest method)

Important
Be sure to design at least one signature template and define users who should get it. See this article to learn how to do so.
Legacy COM Add-in deployment

Important
The COM Add-in works only with CodeTwo Outlook signatures, so make sure that CodeTwo Email Signatures 365 operates either in Outlook or combo mode in your organization (learn more about signature modes). You also need to create and configure at least one Outlook (client-side) signature rule. See our guide on that
