You are adding a new keyword expression to match your content filtering. When you save the keyword, you get the error message "Unable to update Keyword List in database".
The error message appears when your keyword expressions have reached the 16K limit of Hosted Email Security (HES) or Trend Micro Email Security (TMEMS) database.
As a workaround, you need to create a new list of keyword expressions, and then add this new list to your content filtering.
