How do I turn off e-mail notifications?

[Ted Beam]

Does anyone know how to turn off notifications for Office 365 groups like the one below? I don't want any automatic e-mails going out to group members. Thanks.

You can do this through Group settings you can find in OWA and in Office Desktop:
1) In OWA, just click on the Group you want to configure and then click on the cog wheel where you will see the notification settings you can set up
2) In Outlook Desktop, just click on the Group you want to configure and then in the Group settings option in the Ribbon

Are you referring to this check box? I already had this unchecked, and Office 365 still sent out the e-mail notification shown in the OP.
