How to update email address of already created Microsoft 365 group? Roles / permissions

Question

Hello. I'm able to create Microsoft 365 groups, but when I try to modify the email address of an already created Microsoft 365 group, I'm not able to perform that action.

My user has the "User Administrator" Azure built-in role assigned. With this role, I can edit the name or the description of the group, but not the email address. I don't see the 'edit' button.

Do you know which Azure built-in or custom role is needed to perform this action?

Thanks in advance,

Álvaro

Yes It is possible, you can add new email ID and you can promote your new Email ID as an SMTP and you can remove your Old Email ID. But performing this steps, you need a global Administrator access.

Please follow below Steps to change Office 365 group Email address:- 

Current SMTP address :- ******@abcd.onmicrosoft.com

Required SMTP address :- ******@abcd.com 

Follow the below steps in power shell using Global Administrator Credentials,

 

• Connect to Exchange Online via Power shell using Global Administrator Credentials and run the below commends. First two commands run separately,

     Set-ExecutionPolicy Unrestricted
  
     Start-service winrm
  

Import-module MSOnline
$UserCredential = Get-Credential
$Session = New-PSSession -ConfigurationName Microsoft.Exchange -ConnectionUri https://outlook.office365.com/powershell-liveid/ -Credential $UserCredential -Authentication Basic -AllowRedirection
Import-PSSession $Session
Connect-MsolService -Credential $UserCredential

• Run the below command to add required SMTP address as an alias. Set-UnifiedGroup -Identity "X" -EmailAddresses: @{Add ="Y"} here X is the Display Name of Office 365 group and Y is the required Email ID. Eg:- Set-UnifiedGroup -Identity "Test o365Group" -EmailAddresses: @{Add ="******@abcd.com"}
• Promote alias as a primary SMTP address, Set-UnifiedGroup -Identity "Test O365Group" -PrimarySmtpAddress "******@abcd.com"
• If not required, you can remove first ID using below command. Set-UnifiedGroup -Identity "Test o365Group" -EmailAddresses: @{Remove="******@abcd.onmicrosoft.com"}

Please note, for updating the Office 365 group SMTP address required Global Administrator access. Hope this will help you and let me know if you are facing any issue on this.
