Hi Gareth, thanks for sharing that detail! If you’re not getting emails from the groups you’re subscribed to, here are a few things to check:
Make sure Focused Inbox isn’t hiding them try turning it off temporarily.
Check your Inbox rules and Sweep settings to ensure nothing is moving or deleting those messages.
For Outlook Groups, confirm that you’ve enabled “Send copies of group conversations and events to members’ inboxes” in the group settings.
Aside from restoring the emails and checking account activity, you can also review any rules or filters that might be moving messages around. For running a message trace, you’ll need to sign in to the Microsoft 365 Security & Compliance Center, go to Mail Flow > Message Trace, and enter the sender/recipient details and date range to see what happened to those emails. If you’re using a free Outlook/Hotmail account, message trace isn’t available, so in that case, If everything looks fine and you still don’t see the emails, it could be a delivery issue. In that case, contacting Microsoft Support or your email admin (if you’re on Microsoft 365) would be the best next step to run a deeper check.
