Configuring the Email settings on O365 Groups


All modern SharePoint Team sites have an O365 group associated with them. The O365 groups have an email address assigned to them. This is usually in the format of Alias@[tenantName].onmicrosoft.com.

As an owner of a group, you can configure the settings to allow external people to email the group, and you can ensure all emails that are received by the group are sent to all members own email inbox.

The examples below are using the browser version of outlook, this can also be done in the outlook client. (Please note buttons and dialog are in different places and look different too)

Configuring Group email settings as an Owner

  • As an Owner of a Group open browser version of Outlook
  • Under Groups find your Group name
  • Click on the ellipse and click Settings.
  • In Group Settings click Edit group

  • Within the Edit group, there are two check boxes.
    • Let people outside the organisation email the group – Until this is ticked, only people within the organisation domain will be able to send an email to the group.
    • Send all group conversations and events to members’ inbox. They can stop following this group later if they want to. – When this is ticked, all emails sent to the group and events, will be automatically sent to all members own inbox. Note: Members can override this setting for themselves, see below “Configuring Group Email settings as a Member”

    The Email address for the group can be found on the above dialog, under Group email address. Typically the email address is <groupAlias>@<tenant>.onmicrosoft.com. See below on “Global Administrators steps to change the Group Email address to the current domain email“.

Configuring Group Email settings as a Member

As a member of a group you cannot change the settings for everyone in the group, nor can you turn on Let people outside the organisation email the group. You can, however, change what emails come to you.

  • As a member of the group open browser version of Outlook.
  • Under Groups find your Group name
  • Click on the ellipse and click Settings.
  • In Group Settings click Edit group

  • You have the option of 4 settings, which are quite self-explanatory:
    • Follow in inbox
      • Receive all emails and events
    • Stop following in inbox
      • Receive only replies to you and the group events (default)
      • Receive only replies to you
      • Don’t receive any group messages

Global Administrators steps to change the Group Email address to the current domain email

To make this change you need the following pre-requisites:

  • Global Adminstrator / Exchange Administrator
  • Microsoft Exchange Online PowerShell Module downloaded and installed
  • The email Domain you are changing to is an accepted domain for your organisation. 

In the below example, it shows how to change the Group (alias: EmailEnabling) email address from EmailEnabling@abcd.onmicrosoft.com to EmailEnabling@abcd.co.uk address.

Note: The below script is untested by myself, as I don’t have access to a environment that has a accepted domain.


#Connect
Connect-EXOPSSession -UserPrincipalName [your UPN];

#Add the Email Address
Set-UnifiedGroup -Identity "EmailEnabling" -EmailAddresses @{Add="EmailEnabling@abcd.co.uk"}

#Promote alias as a primary SMTP address
Set-UnifiedGroup -Identity "EmailEnabling" -PrimarySmtpAddress "EmailEnabling@abcd.co.uk"

#Optional, remove original email address
Set-UnifiedGroup -Identity "EmailEnabling" -EmailAddresses @{Remove="EmailEnabling@abcd.onmicrosoft.com"}
