How to Export Office 365 Distribution Group Members to CSV Files

Office 365 distribution groups allow administrators to send invitations or messages to multiple members using a single email address. However, there are times when administrators may need to rebuild these groups or share member details across multiple groups. Instead of individually accessing each distribution group through the Exchange Admin Center (EAC) online, having member information readily available in a CSV file can be far more convenient.

In this blog, we will explore various methods for exporting Office 365 distribution group members to CSV file format, ensuring you have easy access to this important information at any time.

Manually Exporting Office 365 Distribution Group Members to CSV

There are two primary manual methods for exporting Office 365 distribution group members to CSV format:

• PowerShell Scripts: This method requires some knowledge of PowerShell, making it less accessible for novice users. However, it is a powerful way to automate the export process.
• Exchange Admin Center (EAC): This user-friendly method does not require extensive technical knowledge and is straightforward to execute.

Exporting Office 365 Distribution Group Members Using PowerShell

To use PowerShell for exporting distribution group members, follow these steps:

1. Open PowerShell as an Administrator and connect to Exchange Online:

   Set-ExecutionPolicy RemoteSigned
   $UserCredential = Get-Credential
   $Session = New-PSSession -ConfigurationName Microsoft.Exchange -ConnectionUri https://outlook.office365.com/powershell-liveid/ -Credential $UserCredential -Authentication Basic -AllowRedirection
   Import-PSSession $Session -DisableNameChecking

2. List All Distribution Groups: Use the following command to find all the distribution groups in your organization:

   Get-UnifiedGroup -ResultSize Unlimited

3. Get Members of a Specific Group: To check who is in a particular group, execute:

   Get-UnifiedGroupLinks -Identity "<GroupName>" -LinkType Members -ResultSize Unlimited

4. Export Group Members to CSV: Once you know which members to export, run this command:

   Get-DistributionGroupMember -Identity "<GroupName>" | Select Name, PrimarySmtpAddress | Export-Csv members.csv -NoTypeInformation

5. Export Members from All Distribution Groups: To transfer all members to a CSV file, use:

   $Groups = Get-UnifiedGroup -ResultSize Unlimited
   $Groups | ForEach-Object {
       $group = $_
       Get-UnifiedGroupLinks -Identity $group.Name -LinkType Members -ResultSize Unlimited | ForEach-Object {
           New-Object -TypeName PSObject -Property @{
               Group = $group.DisplayName
               Member = $_.Name
               EmailAddress = $_.PrimarySMTPAddress
               RecipientType = $_.RecipientType
           }
       }
   } | Export-CSV "C:\\Office365GroupMembers.csv" -NoTypeInformation -Encoding UTF8

Using the Exchange Admin Center to Export Members to CSV

For those who prefer a graphical interface, you can use the Exchange Admin Center (EAC) to export distribution group members:

1. Log into Office 365 with global administrator credentials. Navigate to Admin Centers and select Exchange.
2. In the EAC, click on Recipients, then select Groups.
3. Choose the desired distribution group, click on the three dots (More) option, and select Export Data to CSV.
4. In the Export Data window, choose your desired columns and click on Export.
5. The members of the distribution group will be exported to a CSV file format.

What Data Will the Exported CSV File Contain?

The resulting CSV file will present data in a structured table format, including:

• Distribution Display Names
• Group Names
• Members’ Names
• Group Aliases
• Primary SMTP Email Addresses
• Member Counts
• Recipient Types
• Authorized Senders
• External Recipient Permissions

Conclusion

Exporting Office 365 distribution group members to a CSV file is an effective way to maintain a record for future analysis and use. Both PowerShell and the Exchange Admin Center provide viable methods for exporting this data, catering to different user preferences and skill levels.
