But in practice, there is a much more simple way - Open web Outlook. Compose a new email. Click 'To'. Go to GAL. Search for the name of the distribution list. Click the plus sign.

How to export a list of members of an email group from Office 365?

Based on my tests and researches, it is not feasible to export distribution list members using UI interface. We can only export the members via Windows PowerShell. To do that, the steps are as follows:

1. Open Windows PowerShell and connect to Exchange Online PowerShell. Here are the commands:

Install-Module ExchangeOnlineManagement (Enter Y to install the module)

Connect-ExchangeOnline (Sign in using admin account and password)

2. Then run the following script to get a csv file about Distribution list.

$Groups = Get-DistributionGroup

$Groups | ForEach-Object {

$group = $_.Name

$members = ''

Get-DistributionGroupMember $group | ForEach-Object {

$members=$_.Name

New-Object -TypeName PSObject -Property @{

GroupName = $group

Members = $members

EmailAddress = $_.PrimarySMTPAddress

}}

} | Export-CSV "C:\DistributionGroupMember.csv" -NoTypeInformation -Encoding UTF8

Here is a screenshot about the result I got:

External email accounts can not send emails to Exchange Server group email addresses

This is a security policy. Open Exchange Management Console. Go to Recipient Configuration | Distribution Group, right-click a group name. Click Properties | Mail Flow Settings | Message Delivering Restrictions. The check box Require that all senders are authenticated restricts external accounts from sending emails to this group.
