Issue: The attachment file name has been replaced by the temporary file name.
Resolution: This security feature prevents users from clicking items with misleading names. When Unicode characters are used in the file path, the file is copied to an ANSI path. When this occurs, temporary file names may be used to ensure that characters that do not have an ANSI equivalent are not replaced with " ? ". To avoid temporary file names being used for attachments, do not use Unicode characters in the file path.
