Title: Users may be unable to search for email or calendar items in Groups in Exchange Online

User impact: Users may be unable to search for email or calendar items in Groups in Exchange Online.

More info: This issue may impact any Groups search in the new Outlook desktop client and Outlook on the web; however, it could also impact additional connection methods where this feature is available. Specifically, when a user enters text into the search bar limited to a Group, no results are returned and there is no indication that the search action was processed. This occurs whether a user hits "Enter" or clicks on the search icon after entering text. General Outlook search isn't affected.
