I tested the following script and works well. You may substituting your own values and proceed with the same script

$userAlias1 = "manu1@cloudcompute.info" $DisplayName = "Test Team Group" $teamsGroupName = "TestTeam" $group = New-Team -DisplayName $teamsGroupName -MailNickname $teamsGroupName -Visibility "private" -Owner "manu@cloudcompute.info" Add-TeamUser -GroupId $group.GroupId -User $userAlias1

Hello Manu, sorry responding late, I was sick OOF last 2 days.

Thanks for the prompt response, the above code I've mentioned does work but I was specifically looking for adding users from a Security Group with the Add-TeamUser cmdlet with a FOR loop.
I did some research for extracting users from a SecurityGroup and then adding through the PowerShell cmdlet but wasn't much of any help.

If you can help with my ask then that would be really helpful. Thanks in advance.!

There are many ways where in which users can become member of teams like participating through office 365 groups, dynamic groups, through a Teams invitation etc. At the same time, Syncing Security Groups with team membership is not a good practice as the updates to the group membership can't reflect in Teams membership.

Following is a reference to create a team from an office 365 group.

Here is a good article explaining the pros and cons of Syncing Security Groups with team membership and you may go through it.

Thanks for the suggestions but I'm not trying to sync members of teams. Let me give you more context.

I am from M365 Security Incident Response Team. I have a requirement in an event of a Cyber Attack / 0 Day Advisories, how soon our Partners / Service Owners can be engaged and stay up to date to take mitigation actions. Our Incident Response team performs several actions below manually for our Partners to take mitigation actions and its a time-consuming process.

Create a new Teams Group

Create 5-7 new Channels in the new Teams Group

Add users to the Teams Group / channels manually from an existing Security Group or Distribution Group.

Create OneNote for the Incident and ensure all the members of the new teams group has access to it

Create docs on SharePoint portal and ensure all the members of the new teams group has access to it.

I imported Teams PowerShell module to create above actions items 1,2,4,5 and I have everything working through PowerShell cmdlet. The only thing I don't have is #3 when it comes to add users from an existing SecurityGroup to the new Teams Group or Channels. Hope the above clarifies my ask and I'm not syncing members of Teams or any SGs from Exchange.

Hi @Dharmendra Mudliar ,

How to add members in teams via PowerShell. I want to add all users from a Security Group - "AAAA" to the new Team I'm creating above?

Based on my test, you can try the using the steps and scripts below:

Connect to both the Teams powershell and Exchange Online powershell.

Run the following scripts below after replacing the values with yours.:
$teamsGroupName = "TestTeam" $groupId = New-Team -displayName $teamsGroupName -Visibility "private" -Owner "owner@contoso.com" Get-DistributionGroupMember "AAAA" | foreach{Add-TeamUser -GroupId $groupId.GroupId -user $_.PrimarySmtpAddress}

Hello Yuki,

Thanks for the prompt response, and sorry for responding late. When I run the cmdlet it was throwing me below error. It looks like I need to import Exchange modules for the below command to run. I tried some Microsoft online links but wasnt helpful to import modules. If you can help with the link for importing the Powershell module for Exchange then that would be great help. Thanks a lot for your help in this regard.

Error: Get-DistributionGroupMember : The term 'Get-DistributionGroupMember' is not recognized as the name of a cmdlet, function, script file, or operable program Check the spelling of the name,

Hi @Dharmendra Mudliar ,

Yes, as mentioned earlier, the script above requires connecting to Exchange Online powershell as well. You can refer to the linked article in my post above or check the document below for details about instructions for how to connect to Exchange Online PowerShell using the EXO V2 module:
