How to disable welcome email notifications on M365 groups

Question

I’m trying to disable welcome notification emails for a Microsoft 365 Group using Exchange Online PowerShell:

Set-UnifiedGroup -Identity "<GroupID>" -UnifiedGroupWelcomeMessageEnabled:$false

However, the cmdlet is not available:

Set-UnifiedGroup : The term 'Set-UnifiedGroup' is not recognized

Even after connecting:

Get-Command Set-UnifiedGroup

---

Environment

PowerShell 7.5.4 (local, Windows)

ExchangeOnlineManagement module installed and imported

Connected using Connect-ExchangeOnline

• Tenant requires admin consent

What I’ve tried

Installed/imported ExchangeOnlineManagement

  Connected to Exchange Online
  
     Verified module is loaded
     
        Verified cmdlet availability
        

Additional context

• I do not have Global Admin or Exchange Admin rights

  What I’ve tried

  • Installed/imported ExchangeOnlineManagement
  • Connected to Exchange Online
  • Verified module is loaded
  • Verified cmdlet availability

• I do not have Global Admin or Exchange Admin rights

Is Set-UnifiedGroup only exposed to users with Exchange Administrator / Global Administrator roles? If so, is there any supported alternative (Graph/CLI) to disable M365 group welcome emails without those permissions?

Answer 1

The Set-UnifiedGroup cmdlet is indeed used to modify Microsoft 365 Groups, including disabling welcome email notifications. However, it is important to note that this cmdlet is only available in the cloud-based service and requires appropriate permissions to execute. Specifically, users need to have either Exchange Administrator or Global Administrator roles to access this cmdlet.

Since you mentioned that you do not have Global Admin or Exchange Admin rights, you will not be able to use the Set-UnifiedGroup cmdlet to disable the welcome email notifications directly.

As for alternatives, without the necessary permissions, you may need to request assistance from an administrator who has the required roles. Currently, there are no supported alternatives via Graph API or CLI that allow you to disable welcome emails for Microsoft 365 Groups without the appropriate permissions.
