I've copied the provided link and followed instructions to add a calendar from the internet but the message (from Outlook) indicates the link is not a valid address. :-/
Can you generate a new iCal link in the Trello Calendar Power-Up by opening your board's menu > clicking on the Calendar Power-Up > clicking on 'Edit Power-Up Settings' > then clicking on the round arrow to generate a new link, then give that new link a try?
We also have a page with screenshots showing the steps to connect your calendar with Outlook: https://help.trello.com/article/1064-using-trello-with-microsoft-outlook
If this doesn't help, feel free to contact our support team directly at http://www.trello.com/contact and we'll be happy to help further!
