Settings for Dynamics CRM Online connector for Office 365 Groups

Hi,

I get the same notification every day and I would like to understand what triggers the process that sends this notification.

I thought it only depended on task activity in a group about the crm record but it is actually always referred to an updated made  on 5/10/2017 2:33:51 PM so I should only receive it once and not every day.

I found this article but no information about my matter.

Any help would be greatly appreciated.

Thank you.
