Problem: 

When a news is posted, users who are members or visitors of the site will receive a notification in Teams (part of Viva Connections). 

It seems that users will receive this notification even when they are not following the site.

Possible workaround:

If the news is to be announced via email or some other channel, you can set a schedule for the news to be posted at a later time.

Steps:

1. Go to the SharePoint site > Click on Site contents > Site Pages

Click on Scheduling

Enable scheduling

2. Create a News or open one that is not published yet.

Click Page details

Turn Scheduling On

Enter date and time to publish the news.

Click Schedule when done

You can only Schedule if you set the publish time to a later time.

3.  View Site Pages

You will see a schedule icon beside the file. You can also show the Publish Start Date column.

When the scheduled time is up, the news page will be published.

Note:

Members of the site will be able to see the news before it’s published.

Visitors can only see the news page after it’s published.
