Installation of the signature preview add-in

CodeTwo Email Signatures for Office 365 Add-in is an Outlook Web Add-in that works with desktop versions of Microsoft Outlook (including Outlook for Mac) and with Outlook on the web (OWA). It lets Outlook users preview server-side signatures that will be added to their emails by the CodeTwo Email Azure Service. This means that the add-in is useful if you selected server-side mode or combo mode when registering your tenant. In the case of combo mode, the add-in allows you to preview server-side signatures (added by the CodeTwo Email Azure Service after emails are sent) only; client-side signatures do not need any preview because they are added directly to your Outlook as you type (via the CodeTwo Signatures Add-in for Outlook).

Important

If you selected client-side mode when registering your tenant, do not install this add-in. Instead, instruct your users to install CodeTwo Signatures Add-in for Outlook as described in this article.


 

The add-in is installed per Office 365 user, not per device. This means that it works in Outlook and OWA on any device the user chooses to sign in with (soon also on mobile clients). The Outlook Web Add-in technology from Microsoft is used to push signatures to Outlook and OWA - you don't need to install any agents or COM/EXE software on your email client.

The add-in can be easily deployed globally to your entire Office 365 organization or it can be installed by individual users. Use the links below for guidelines.

Important

Before you deploy the add-in, make sure that CodeTwo Email Signatures for Office 365 is configured in your organization. Learn more

The signature preview add-in does not work with client-side signatures - these signatures are added directly as you type an email in desktop versions of Microsoft Outlook. Learn more about signature modes

After the installation of the add-in, server signature previews are displayed while composing messages (Fig. 1.).
