In Office 365 Exchange how does one obtain a list of existing dynamic distribution groups? Is power shell required?

You can see your groups via web UI: Exchange admin center -> recipients -> groups Then you need to search -> advanced search provide recipient types "Dynamic distribution groups" and OK it

enter image description here

Powershell is not required, but is a good option: You need to connect to Exchange Online session as per Microsoft Technet article.

Supply your Office365 admin user credentials: $UserCredential = Get-Credential

Then create a session(one line): $Session = New-PSSession -ConfigurationName Microsoft.Exchange -ConnectionUri https://outlook.office365.com/powershell-liveid/ -Credential $UserCredential -Authentication Basic -AllowRedirection

And finally Import-PSSession $Session

When connected issue Get-DynamicDistributionGroup which will give you the list.

  • Using powershell, I'm able to get a list using Get-DistributionGroup but not using Get-DynamicDistributionGroup, as that command does not exist when I try to use it. – leeand00 Jul 15 '16 at 13:01

    Make sure there is no error when you connect to office 365 session. I think you might miss some cmdlets if you have PowerShell execution policy set too restricted. – Grigory Sergeev Jul 15 '16 at 13:05
  • I ran Set-ExecutionPolicy -ExecutionPolicy ByPass and then tried your powershell suggestion again, but I still don't end up with the Get-DynamicDistributionGroup I do however have a Set-DynamicDistributionGroup, I don't really want to use it though. I also received something about setting an AllowClobber parameter when importing them, and then a bunch of commands that I assume are local and that importing them would use a proxy to call it remotely instead of the local ones. – leeand00 Jul 15 '16 at 15:16
  • Is it possible that the Get-DynamicDistributionGroup has been deprecated by Get-DistributionGroup? – leeand00 Jul 15 '16 at 15:20

    Okay, it seems you already have Exchange powershell module on the machine where you run this session. AllowClobber would allow to merge modules, if I'm not mistaken. I would suggest you follow the article's section "What do you need to know before you begin?" to avoid any confusion. Dynamic Distribution Groups wouldn't deprecate regular DGs. – Grigory Sergeev Jul 15 '16 at 15:22

You can use Exchange admin center to view all available dynamic distribution group. else you can use below PowerShell commands.

$Credential=Get-Credential -Credential $null 
$Session = New-PSSession -ConfigurationName Microsoft.Exchange -ConnectionUri https://outlook.office365.com/powershell-liveid/ -Credential $Credential -Authentication Basic -AllowRedirection  
Import-PSSession $Session -AllowClobber
Get-DynamicDistributionGroup

viewing members of a Dynamic Distribution Group are not feasible in the Office 365 Admin Portal.PowerShell is the only way to view members.
