To get detailed information on each application, consult the table below :
| Application name | Application purpose | When it is created |
|---|---|---|
| CodeTwo Email Signatures 365 (legacy name: CodeTwo Email Signatures for Office 365) | To create a link between CodeTwo Admin Panel and your Microsoft 365 tenant | On creating a CodeTwo Admin Panel account Important: The app appears on the Integrated apps page only if you select Consent on behalf of your organization when accepting the app's permissions. However, it doesn’t need to be visible there for CodeTwo Email Signatures 365 to work properly. |
| CodeTwo Signatures Add-in for Outlook (legacy name: CodeTwo for Outlook / CodeTwo Signatures*) | To preview cloud (server-side) signatures or automatically add an Outlook (client-side) signature in Outlook and OWA | On deploying the modern CodeTwo Signatures Add-in for Outlook in the Microsoft 365 admin center * If you see CodeTwo Signatures instead of CodeTwo Signatures Add-in for Outlook on the Integrated apps page, it means you deployed the add-in by providing a link to its manifest file. If the manifest file changes in the future, the add-in will continue to work, but it will no longer get automatic updates. Because of that, it is recommended that you remove the add-in from your Microsoft 365 tenant and deploy it again from the Microsoft 365 admin center. |

In order to access the Enterprise applications page to review the CodeTwo apps, perform the following steps:
