Hello,

  • I was creating a group using Exchange admin center, I followed at the steps from General, Owners, Members till the final step.
  • As I click create, it give me an error "Group Creation Failed - Response Content is Null".

I changed name/alias to ensure it is unique but the issue persist.

I'm not sure what to do at this point

Hi Jay- I figured out the issue causing that problem. It was a flag that I selected in the general setting.

"Make this group a security group", once I de-select it, it worked.

    Hi Rady, 

    Thank you for the details provided.  

    Since you're using Exchange Online and have already tried changing the group name and alias, I would suggest the following troubleshooting steps: 

    1. Try creating the group in an InPrivate/Incognito window 

    This helps rule out browser cache, cookies, or extension-related issues that can sometimes affect Exchange admin center operations. 

    • Open an InPrivate window in Microsoft Edge or an Incognito window in Google Chrome. 
    • Sign in to the Exchange admin center. 
    • Attempt to create the group again using the same settings. 
    • Let us know whether the group is created successfully or if you receive the same error message. 
    1. Try creating the group using Exchange Online PowerShell 

    This can help determine whether the issue is specific to the Exchange admin center interface. 

    • Open Windows PowerShell as Administrator. 
    • Install the Exchange Online PowerShell module (if it isn't already installed): Install-Module ExchangeOnlineManagement 
    • Load the module: Import-Module ExchangeOnlineManagement 
    • Connect to Exchange Online: Connect-ExchangeOnline 
    • Create the group using one of the following commands: 
      • For a Microsoft 365 Group: New-UnifiedGroup -DisplayName "Test Group" -Alias TestGroup 
      • For a Distribution Group: New-DistributionGroup -Name "Test Group" -Alias TestGroup -PrimarySmtpAddress ******@yourdomain.com
    •  After running the command, verify whether the group was created successfully: 
      • For a Microsoft 365 Group: Get-UnifiedGroup -Identity TestGroup 
      • For a Distribution Group: Get-DistributionGroup -Identity TestGroup 

    For more information, please refer to Exchange Online PowerShell | Microsoft Learn 

    I hope this information is helpful. Please follow the steps above and let me know if it works for you. If not, we can continue working together to resolve the issue.  

    If you found the response useful, please consider marking it as accepted, as this may help other community members who are looking for similar guidance.  

    Thank you for your patience and understanding. I look forward to continuing the conversation.
