Every time an event is updated, all participants receive an update email. How can I deactivate this?

Every time an event is updated in Zoho CRM (e.g. change description, link to Lead) every participant of this meeting gets an update email. Another customer noticed this problem years ago in the Japanese community:

https://help.zoho.com/portal/ja/community/topic/any-time-an-event-is-updated-on-zohocrm-calendar-it-sends-multiple-invites-to-the-participants-how-do-i-stop-that-from-happening

Is there a simple setting to deactivate these update mails?

This "feature" may be useful to some customers, but it is a real mess for us. Especially with the connection to Outlook. The descriptions in outlook are nicely formatted, but the Zoho CRM only accepts blank text only in the "description" field. Now when this meeting is linked to a lead or contact, the system thinks the description has been changed and sends out update emails.
This is unbearable, as our customers are bombarded with unnecessary and poorly formatted emails.
