@petkir what is the status on this one?
The event is ending with October and this will mean that this won't count toward the Hacktoberfest event if you participated in this one (here there is nothing we may do about it)
BUT a PR for this issue will be created even after October this will still count to get the Refresh Ranger badge from the Microsoft 365 and Power Platform Community

Hi @Adam-it

Currently, the following providers are implemented:

• SharePoint: Same domain requests are working.
• iCAL / RSS / WordPress: Mostly functional, but dependent on CORS settings.
• Exchange Calendar Feed: Not working due to CORS issues.

Problem Description:

Originally, to avoid CORS problems, a proxy provider was used, but it returns Access-Control-Allow-Origin: *.
This does not accapt my Edge Browser on a SharePoint Page.
When I set the fetch mode to mode:'no-cors', I receive a successful response of type response.type === 'opaque'.
While this allows me to download the data to the client, but I'm unable to manipulate the data using JavaScript.

I have experimented with other proxy providers and various Edge plugins, but none have proven to be effective solutions.

One potential solution I see is starting a web browser on localhost to make the request. However, there are no existing examples in this sample gallery that include an additional Azure function or something else.

on the other hand removing support for the Exchange Calendar Feed is also a solution, as it is referred to as the Exchange Public Calendar so ...

So what do you think @Adam-it : self-hosted proxy or remove the Exchange iCal support?

after playing hours i would remove the support for EX, because this is a thing of minutes.
