Groups Not Showing in Outlook or Emailing Members

Situation

All Microsoft Teams and SharePoint sites include a Group Distribution Email.  Every group should be searchable in Outlook as well as have the ability to be used to email all members.  Sometimes, this behavior doesn't perform as expected and needs support from UK's Information Technoloy Services to resolve. If you're experiencing these issues, this article aims to offer a solution. 

Problem Behavior

I. Group Not Searchable in Outlook

When in Outlook Mail View, right click on Groups in the left pane, then 'Browse Groups'. If your group cannot be found in the search results, then this applies to you.

II. Group not Showing in Groups List in Outlook

When in Outlook Mail View, right click on Groups in the left pane, then 'Browse Groups'. If your group can be found in the search results but, after you add it it doesn't show in your group list, then this applies to you.

III. Email Doesn't Send to Group Members

When writing an email using the Group Distribution Email Address, if you send the email and members don't receive it, then this applies to you.
