We encourage customers who are currently using the deprecated add-in to fully switch to the modern CodeTwo Signatures Web Add-in for Outlook & OWA.

The Web Add-in replaces the CodeTwo Email Signatures for Office 365 Add-in (preview add-in), which is now deprecated. Find out more about this feature in the user’s manual Signatures change in real time as users make changes to their email (add or remove recipients, use keywords, etc.). If you configured different signatures for different recipients, the Web Add-in’s pane will show all available signatures. Users can use the add-in to see what signature(s) will be added to their email in the cloud (after the email is sent) while they compose it in Outlook and OWA. Our Web Add-in now also supports the server-side (cloud) signature mode.


The Web Add-in works with new Outlook for Mac (with new UI) connected to a Microsoft 365 subscription, Version 16.59 (Build 22031300) and newer. Support for Outlook for Mac (early access) The new version also comes with advanced configuration options that let you change how the Web Add-in interacts with various Outlook settings.
