How we integrate with Office 365 to add email signatures

CodeTwo Email Signatures for Office 365 uses Exchange Online email connectors to integrate with Office 365 tenants of our clients and then safely reroute their email through our signature services on Azure. Since uninterrupted email flow is critical, we do our best to keep this integration the most secure and reliable on our end.

One of the latest Microsoft articles demonstrates the way third-party apps can integrate with Office 365 (where email add-on service installation is not allowed). The article uses a fictional service called ‘Contoso Signature Service’ to picture what such integration should ideally look like. Email signatures? Connectors? Does it ring a bell? That’s right! This is the exact same approach we have been using in CodeTwo Email Signatures for Office 365 since day one. The only difference is that we have automated the integration process completely on our end. Meaning, every step, from setting up the connectors, right down to assigning a required TLS certificate is done automatically by a specially designed wizard in our program.

After the setup is completed, the mail flow looks the same way, as on the diagram from the Microsoft article:
