SOP: Sending an Email to a Microsoft 365 Group from Outlook

For Staff

Overview

Sending an email to a Microsoft 365 Group allows you to communicate with all group members at once while keeping conversations organized within a shared mailbox.

Unlike traditional distribution lists, Microsoft 365 Groups provide a shared conversation history that allows team members to view previous discussions, collaborate more effectively, and reference information later.

Requirements

Before sending email to a Microsoft 365 Group, verify the following:

• You are a member of the Microsoft 365 Group.
• The group is mail-enabled.
• You have access to Outlook on the web or Outlook desktop.
• The group allows members to post messages.

Step-by-Step Instructions

1	Open Outlook Go to Outlook on the Web. Or open the Outlook desktop application.
2	Locate the Group In Outlook Web or New Outlook: Select Groups in the left navigation menu. Choose the Microsoft 365 Group you want to email. In Classic Outlook: Expand the Groups section in the folder list. Select the desired group.
3	Create a New Group Message Select New Conversation in Outlook Web or New Outlook. Select Send Email or New Conversation in Classic Outlook. The group email address is automatically populated in the recipient field.
4	Compose Your Message Add a clear and descriptive subject line. Enter the content of your message. Attach files or include hyperlinks when needed. Use OneDrive or SharePoint links for documents that will be updated over time.
5	Send the Email Select Send. After sending: The message is stored within the shared group inbox. Group members can view the conversation. Replies remain organized within the group conversation thread. The discussion becomes part of the group's collaboration history.
