error message in outlook

I get every now and then the following error message

Task 'Internet Calendar Subscriptions' reported error (0xF5904005) : 'Cannot verify or add the calendar to Outlook. Make sure the following link is a valid calendar link:

Any explanation?
Thanks

Hello Talal,

Please clarify - when exactly do you see this message? When you open Outlook, when you add your iCal feed for the first time? Also, is there any specific pattern regarding this issue, for example does it only happen at certain times of day?


Best regards,
David
