Manage Office 365 Groups using Azure AD Powershell module

Earlier you can manage modern Office 365 Groups (or Unified Groups) through Exchange Online Powershell module. Now the Azure AD Powershell team introduced new AzureADMSGroup cmdlets to provide the functionality of Microsoft Graph to create and manage unified groups, which includes creating modern O365 groups and dynamic groups through Powershell.

Before proceed, run the below command to connect Azure AD Powershell for Graph module:

Connect-AzureAD

Create new Office 365 Group

In exchange module we need to run New-UnifiedGroup cmdlet to create an Office 365 Group, here you have to use the New-AzureADMSGroup cmdlet to create a new Office 365 Group.

New-AzureADMSGroup -DisplayName "Test O365 Group" -MailNickname "TestO365Group" -GroupTypes "Unified" -Description "This is a test group" -MailEnabled $true -SecurityEnabled $true

Note: When you create a group using New-UnifiedGroup, the mailbox will be created immediately. When you use New-AzureADMSGroup, first the group object will be created in AzureAD and the group object synchronized with Exchange Online, which then creates the group mailbox, so there may be some delay in setting up group mailbox for the new group that was created by New-AzureADMSGroup.

Get a list of all Office 365 Groups

In Exchange module, you have to use the command Get-UnifiedGroup to retrieve all unified groups, with Azure AD Powershell you can achieve the same using the Get-AzureADMSGroup cmdlet.

By default, the Get-AzureADMSGroup cmdlet gets information about all types of available groups in Azure Active Directory.

Get-AzureADMSGroup  -All:$true

We need to apply filter to list only Office 365 groups alone.

Get-AzureADMSGroup -Filter "groupTypes/any(c:c eq 'Unified')" -All:$true

Export report to CSV file:

Get-AzureADMSGroup -Filter "groupTypes/any(c:c eq 'Unified')" -All:$true |
Select-Object DisplayName, Mail, Visibility |
Export-CSV "C:\O365Groups.csv" -NoTypeInformation -Encoding UTF8

Find members and owners of an Office 365 Group

With Exchange module you can list group members and owners by using the Get-UnifiedGroupLinks cmdlet, here you have to use the command Get-AzureADGroupMember to find members and need to run the command Get-AzureADGroupOwner to list owners.

Get-AzureADGroupMember -ObjectId (Get-AzureADGroup -SearchString "<GroupName>").ObjectId

List owners for the given group:

Get-AzureADGroupOwner -ObjectId (Get-AzureADGroup -SearchString "<GroupName>").ObjectId
