Update 5/11/2018 Released Version 2.3 to fix an an issue with single pool selection using the ISE and add last run reminders

About the tool

This is a script that adds/maintains the relevant Australian Holidays to your Skype4B  / Lync environment for the next 12 months based on data available from the Australian Government Website.

I re-wrote most of the script from scratch and added a whole bunch of code to try and catch a lot of the errors etc that happened in the older versions. I’ve also tried to make it alot simpler to use for everyone that’s not me 

Data is taken from http://www.australia.gov.au/about-australia/special-dates-and-events/public-holidays and I have done my best to be as error free as possible.

Shout of to Greig in Sydney for beta testing and providing the red pen. That guy would have made a brilliant English teacher.



Download, and run on a Frontend or any machine with the Lync / Skype4B management tools installed

The script will attempt to detect your Skype4B Setup and proceed accordingly

If you already have holiday sets with the name names or you need to add a country code. You can specify a string with the -RGSPrepend parameter to prepend to the Holiday set names.

Unattended (Scheduled Task) execution

You can also use the script on a scheduled task to automatically pull and update the latest holidays on a monthly basis if your server has internet access.
Simply specify -FrontEndPool <FEPoolFQDN> and -Unattended in the scheduled task.

You can also still specify the -ServiceID and -Unattended parameters at the commandline if you want to specify the ServiceID directly.
Use Get-CsRgsConfiguration -Identity Frontend.Skype4bAdmin.com to see valid service id’s

Note either of these options will disable script update checking. So it pays to check manually every now and again.

Applying the Holiday sets

After you have run the script, you can find the time frames in the Response Groups Editor, Simply tick the states you want the workflow closed for.
Each of the states already includes the National holiday set, so there is no need to tick both.
I’ve also added a new reminder feature showing when the script was last run in the RGS editor.

Fork Me

As alot of my code is open source, I’ve moved from storing my Git repo on VSTS over to GitHub. Feel free to fork the code for your own purposes over here



The default holiday set names are “National”,”Victoria”,”New South Wales”,”Queensland”,”ACT”,”Northern Territory”,”South Australia”,”Western Australia”,”Tasmania”
If you need to change these for whatever reason update the following lines in the script

$National = $RGSPrepend+"National"
$Vic = $RGSPrepend+"Victoria"
$NSW = $RGSPrepend+"New South Wales"
$QLD = $RGSPrepend+"Queensland"
$ACT = $RGSPrepend+"ACT"
$NT = $RGSPrepend+"Northern Territory"
$SA = $RGSPrepend+"South Australia"
$WA = $RGSPrepend+"Western Australia"
$Tas = $RGSPrepend+"Tasmania"
