Powershell get-msolconact -all does not return ProxyAddresses data

When connected via (Windows Azure Active Directory Module for Windows PowerShell)
$O365Session = New-PSSession -ConfigurationName Microsoft.Exchange -ConnectionUri https://ps.outlook.com/powershell -Credential $O365Cred -Authentication Basic -AllowRedirection -verbose
$importcmd = Import-PSSession $O365Session -verbose
Connect-MsolService -Credential $O365Cred
Add-pssnapin Microsoft.Adfs.Powershell

When I run Get-MSOLcontact -all against my O365 contacts, it returns the field Proxyaddresses with nothing in it.

If I execute Get-MSOLcontact -objectid <objectid> it DOES return the ProxyAddresses. What is going on?

Some properties are considered 'expensive', and are not returned when you use bulk cmdlets. The usual workaround is to use something like this:

Get-MsolUser -all | ft DisplayName, @{n="ProxyAddresses";e={(Get-MsolUser -ObjectId $_.ObjectId).ProxyAddresses}}

Open in new window

Or just use the corresponding EO cmdlet:

Get-MailContact -ResultSize Unlimited

Open in new window

The following command DOES return the ProxyAddresses field correctly.

Get-MsolContact -all | ft DisplayName, @{n="ProxyAddresses";e={(Get-MsolContact -ObjectId $_.ObjectId).ProxyAddresses}}
