Guest cannot send email to team address

[ChrisMul]

Hi folks. Some help for a novice please: I cannot find a setting to allow guests in a team to send to the team email address. A Microsoft error comes back:

The group XXXX isn't set up to receive messages from [guest email address].

But I can't find how to change the setting.

@ChrisMul Hello, you can change this setting for the group.

This is how it look like in the admin portal.

This is how it looks from within Outlook and the Group settings (to the left i the Navigation pane and then select Settings in the menu bar).

Thanks so much @ChristianBergstrom. I was looking for settings within Teams not MS 365 groups. Appreciated.
