While trying to add a Holiday to one of our Auto Attendants I was greeted with a “useless” error message, so in hopes of getting a better picture of what was going on, I opened up my powershell console and connected with our Tenant

$session = new-CsOnlineSession
import-PSSession $session
Export-CsAutoAttendantHolidays
cmdlet Export-CsAutoAttendantHolidays at command pipeline position 1
Supply values for the following parameters:
Identity: <snip>
Next generation provisioning is not enabled for your tenant. Please contact support to enroll.
    + CategoryInfo          : NotSpecified: (:) [Export-CsAutoAttendantHolidays], OnlineCmdletException
    + FullyQualifiedErrorId : FeatureIsNotEnabledForTenant,Microsoft.Rtc.Management.Hosted.OAA.V2.ExportCsAaHolidaysCmdlet
    + PSComputerName        : admin0e.online.lync.com

The online documentation for Export-CsAutoAttendantHolidays does not mention this “next generation provisioning”, so what next…

As usual, I fired up Google (bing & ddg same result), to see if anyone else had run into this issue, but to my surprise there were no results, don’t think I’ve had that happen before…

Currently waiting for more information from Microsoft Support; to be continued
