Microsoft has deployed (or currently being deployed) an update to the Office 365 Groups feature to allow customer to use multi domain in Groups as well as the ability to update the privacy type (public and private) AFTER the creation.

 

Multi Domain Support

The multi domain support is added and available only through PowerShell. It is not available using the GUI when creating a new group and require an administrator to setup an email address policy.

To create an email address policy to take advantage of this new feature:

  • Connect to your Exchange Online tenant

$cred = Get-Credential

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

Import-PSSession $Session

  • Create your email address policies to match your requirements; as example these commands create 2 policies: one if the owner is member of the Finance department, the other if the owner if member of the HR department

New-EmailAddressPolicy -Name FinanceGroups -IncludeUnifiedGroupRecipients EnabledEmailAddressTemplates "SMTP:@finance.groups.mycompany.com","smtp:@groups.mycompany.com” ManagedByFilter {Department -eq ‘Finance’} -Priority 1

New-EmailAddressPolicy -Name FacultyGroups -IncludeUnifiedGroupRecipients EnabledEmailAddressTemplates "SMTP:@hr.groups.mycompany.com","smtp:@ groups.mycompany.com” ManagedByFilter {Department -eq ‘HR’} -Priority 2

Changing the Privacy Type

Until then, it was not possible to change the privacy type (private or public) for an Office 365 Group after the creation.

Now, the owner can edit it. To do so, connect to Outlook On the Web (formerly Outlook Web Access) and go to the Contacts and select the group you want to change the privacy type

Then Edit the group and change the privacy type
