Last week when working with Service Manager I found this event again, in the Operations Manager log on the Service Manager server. Event ID 33880 from Health Service Module. It is generated when you try to send notification to a user, for example affected user, with a notification template that don’t support the user CI localization settings. More information about that scenario here. How to fix it? Make sure you have the same localization settings in your notification template and on your user CIs.
