* Company information and user contact details are synchronized from Entra ID (previously Azure Active Directory or AAD), both in CodeTwo and in mail flow rules. Thanks to that, email signatures are personalized and contact details are always up to date. CodeTwo gives you an additional benefit of managing contact details using a separate tool, without the need to change anything in Entra ID. Learn more...

** Available for Outlook (client-side) signatures. CodeTwo Email Signatures 365 can work in three different modes – cloud (server-side), Outlook (client-side) or a combination of those two. Cloud mode guarantees that all emails are stamped with the right signature after they are sent and that users do not make any changes to their email signatures. Outlook mode allows users to easily choose the signature in Outlook while composing their email and add signatures even to encrypted emails. Learn more...
