Overview

This article provides information about the limitation of Kerio Outlook Connector (KOFF) when sending emails with emoji characters, which display as Chinese characters/letters. The email HTML formatting differs from Plain Text and Rich Text options.

Diagnosis

Chinese characters show due to incorrect conversion of emoji characters, UTF-8 encoding/decoding transmission failures, and changes in font-related XML files. The issue occurs because of the MAPI protocol limitations.
