There are two ways to allow more users to receive signatures by editing the transport rule:

• Remove the condition limiting the scope of senders to a specific group. This will cause all emails to be processed by CodeTwo Email Azure Service.
• Add further groups to the existing scope of senders.

Remove the condition limiting the scope of senders to a specific group

Make the following changes to the transport rule to remove the condition limiting the scope of senders to a specific group. As a result, signatures will be added to messages sent by all users inside your organization.

1. Open the transport rule.
2. Find the condition The sender is a member of and remove it by clicking the Remove button (Fig. 5.).
