Hi @Arine Fitriani,
As a Global Administrator or SharePoint Administrator in Microsoft 365, you can turn off these notifications for all users for compliance purposes. If you allow these notifications, users can select to turn them off. Currently, notifications are sent for the following activities:
SharePoint news published (users receive these based on relevancy)
Page comment (sent to the page author)
Page comment reply (sent to the page author and the author of the comment that is being replied to)
Page comment mention (sent to person @ mentioned)
Page like (sent to the page author)
You could refer to following steps to block notifications
- Go to Settings in the SharePoint admin center, and sign in with an account that has admin permissions for your organization.
- Select the Notifications setting for SharePoint.
- Select or clear Allow notifications.
You can also control this setting in PowerShell by using Set-SPOTenant -NotificationsInSharePointEnabled.
