Supported platforms and requirements

CodeTwo Email Signatures for Office 365 does not require installation of any components in the client's environment. This is because the software's main engine - the CodeTwo Email Azure Service - is operated by CodeTwo on Microsoft Azure servers where emails are processed seamlessly, without client's engagement. Thus, the program's end users do not have to install anything. The administrator of the client's Office 365 tenant must only run the following two components:

  • CodeTwo Admin Panel: a web-based panel for adding new tenants, managing payments, monitoring the service status as well as configuring connectors and transport rules.
  • CodeTwo Email Signatures for Office 365 Manage Signatures App: a ClickOnce app for signature management.

A third component (CodeTwo Email Signatures for Office 365 Custom Attributes Sync App) is required if custom AD attributes need to be manually synchronized in an Office 365 tenant.

Additionally, the CodeTwo Email Signatures for Office 365 Add-in allows end users to preview signatures while composing emails in Outlook and OWA (soon also on mobile clients).

Study the tables below for details on the program's requirements.
