Question

Hello I need to modify the main mail address of an Office 365 group.

How can I change 1st part and domain:

Example: I need to change admin@contoso.com to group@contoso.fr How can I do this ?

Answer 1

I was looking for the same thing, and it's now possible (from january 2019!). I found these commands who perfectly works:

1. Connect to PowerShell (with admin rights)
2. Allow Remote Signed scripts:

Set-ExecutionPolicy RemoteSigned

3. Log with O365 admin user:

$UserCredential = Get-Credential

4. Create new session:

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

5. Import session:

Import-PSSession $Session

6. Set the new address:

Set-UnifiedGroup -Identity admin@contoso.com -PrimarySmtpAddress group@contoso.fr

That perfectly works for me, even if you're trying to send from external email.

Don't forget to return to the default execution policy:

Set-ExecutionPolicy Default

Enjoy it :)
