[Exchange Online] Remove cancelled Outlook meetings using PowerShell and EWS!


Actually it is 23:13 CEST, but still!

Some time ago I have published a script to remove cancelled calendar meetings from Exchange OnPremise (I have tested that on Exchange 2010).You can find this script here:


I am currently at the end of the migration to Exchange Online from Exchange 2010 environment. Few days ago I had a call telling me that seems that the cancelled meetings are not being removed from room calendars as they supposed to be.

Yup, I forgot to rewrite the script…

Bartosz Bielawski will join our PPOSH #3 !in person! with a surprise session!

Hello Everyone,

As you might know, there is a third session of Polish PowerShell User Group this thursday (27.07.2017) at 17:00.

The breaking news is…Bartosz Bielawski – a PowerShell MVP  –  will join our meeting in person with a surprise session (we still ocnfirming the agenda).

If you do now know who Bartek is (shame on you!) here is some info:


Bartosz (Bartek) Bielawski is a busy Windows engineer for Optiver, an international company. He loves PowerShell and automation and that love earned him the honor of Microsoft MVP. He shares his knowledge mainly in PowerShell Magazine, in his blogs, and through articles published in the Polish “IT Professional” magazine. He is also a co-author of the “PowerShell Deep Dives” book, and author of “Windows PowerShell 5.0 Biblia”.


We (PPOSH guys) met Bartek on PSConf.EU one year ago, and we were talking about him joining our sessions this year. Bartek is now on holidays in Poland, and he cheerfully agreed to join us!


poweshell_biblia_200We are also working on getting some copies of his book “Windows PowerShell 5.0 Biblia” from Presscom publisher to be signed and handed out on our meeting! 🙂





If you still got a free evening on thursday, I think I just gave you an idea what you can do 🙂

So #DoSomethingForYourself join us on 27.07.2017, 17:00 at Objectivity!

Same code – different output. ISE vs PS Console and VSCode.

Hey Guys,

Help needed here… I was just finishing another function for UK Power Cuts (still dirty as pile of dung I know, but works :P) while I noticed something weird.

Scottish and Southern have power cuts info in Javascript generated tables, the thing is, each position might be slightly different / have different fields – for instance one position will not have information about estimated time Engineer will be on place.

Let me show you what I mean on the, picture as we all know it is worth a thousand words:ScottishAndSouthern.jpg

PowerShell Conference EU 2017. Not just about coding.

5th of May, cloudy afternoon in Hanover city. We are heading towards a car parked on the side road, the driver is waving to us from far away and we respond with the same.

There are three of us, with rather heavy breath, without jokes as usually we get in the car firstly leaving our luggage in the trunk. Faces are smiling, but it is kind of smile that you can interpret more like powerless acceptance of fate… Sitting on the back seat, whilst one side on me was really sad and flooded in despair, the second one was thinking about lovely wife and sweet 1 year old son. Not seeing them just for 4 days was really sad experience as for me they are whole world. So it happened… we were on our way back,  left Hannover, already cutting the highway with KIA for around 20 minutes like a really sharp knife cuts butter. I was looking through the window and hundreds of images were going around my head, my eyes stuck in one point whilst being gently swaying on the German highway. All of a sudden my right hand became a focal point for my vision…

And it took my pupils exactly 1 second to double the size, I stopped my eyes on one point and screamed:
