Group emails not coming to my inbox

I had that problem too when I created a Microsoft 365 group - e-mails only went to the group folder in Outlook and not the Inbox - and unfortunately people didn't notice the messages in the group folder.

Solution: go to admin.microsoft.com and log in as admin (or instruct your mail admin to do this). Click Teams and Groups on the left. Click the group you would like to edit, and a panel opens on the right. Click the "Settings" tab and check the box "Send a copy of team mails and activities to team members' inbox" (I'm translating this from Danish, so the wording may not be 100% spot on). This solves everything for me, and mails sent to the group now appear in people's inbox.
