Group emails not coming to my inbox

ermanu, took me awhile when this happened to one of my staff members.  First I had my staff member check in Outlook to make sure she could actually see the group at the end of her folder list.  It was there and she was definitely in the group because there were hundreds of messages she had never seen.   While in the group email, I found something under group settings on the ribbon.  Under "Follow in Inbox" her "All Email and Events" was not checked.  She checked it and problem is now solved.  Hope this works for you!
