Hi Gabi and welcome back. 🙂
iCal Importer can import events from any calendar with an iCal URL. So, for example, if the Outlook calendar is hosted online, then it likely does have a URL that can be entered into the iCal Importer settings and used to import events.
To be honest, I do not have an Outlook calendar myself, but I did find this article that explains how to set up an iCal URL in Outlook. That might be a good place to start.
I should also note that I’ve heard about some Outlook quirks in the past, related to the way that Outlook sets up its iCal feed. I am not aware of any issues at the moment, but thought I’d mention it anyway and also point out that we have a nice refund policy, should anything not wind up working the way you would expect it to.
Does this help answer your question? Please let me know. 🙂
Cheers,
Geoff
