The latest 1.1.166.0 release offers three new commands:

Get-MsolCompanyAllowedDataLocation
Retrieves all the current allowed data locations of a company from Azure Active Directory.
The Get-MsolCompanyAllowedDataLocation cmdlet can be used to retrieve all
the current allowed data locations of a company from Azure Active
Directory. If a company has not opted in the multinational feature or has
no allowed data locations, then the cmdlet will return an empty list.

Set-MsolCompanyMultiNationalEnabled

Enables the multinational feature for a service type for a company with Azure Active Directory.

The Set-MsolCompanyMultiNationalEnabled cmdlet will attempt to enable the multinational feature for a service type for a company in v1. Note that disabling/opting out from the multinational feature for a service type is not supported in v1. This cmdlet will return an error with the failure reason if the multinational feature for a service type cannot be enabled for a company.

Example: Set-MsolCompanyMultiNationalEnabled -ServiceType MicrosoftCommunicationsOnline -Enable $True

Set-MsolCompanyAllowedDataLocation

Sets an allowed data location for a service type for a company in Azure Active Directory.

The Set-MsolCompanyAllowedDataLocation cmdlet will attempt to set an allowed data location or update an existing allowed data location for a service type for a company in v1.

Example:  Set-MsolCompanyAllowedDataLocation -ServiceType
MicrosoftCommunicationsOnline -Location EUR
