The following new features and enhancement changes were made in GroupWise 18.4:
Alternate From Addresses: You can use other corporate email addresses instead of just your preferred/default email address when you send and reply to email. See Using Alternate From Addresses.
Folder Colors in the Client: You can now add colors to folders in the GW client to help organize your mailbox. See Adding a Folder Color.
Emojis can be added to messages: Emojis are now available to be added to HTML messages. A button has been added to the HTML toolbar to let you select emojis. See Adding Emojis to an HTML Message.
Print using default browser: The GroupWise client now uses the user’s default browser when printing HTML messages.
