Customers in all regions who have Phone System SKU (formerly known as CloudPBX) will now be able to create Holiday schedules using the new holidays Auto Attendant UI, or in PowerShell:
Up to 20 different Holidays, containing max 10 date ranges each, can be created for an Auto Attendant. Admins can select start date and time, and also end date and time for each date range in their Holiday schedules.
All Holidays must have unique names and, though nested and overlapping Holidays are allowed, two Holidays cannot start on the same date and time in the same Auto Attendant.
A set of PowerShellcmdlets to export Holiday schedules from one Auto Attendant and import them into another Auto Attendant is also available:
