Hello:

I'm running Thunderbird 17.0.8, Lightning 1.9.1, and Provider for Google Calendar 0.18 on both Win XP SP3 and Win 7 machines. With the latest TB update, I can no longer view calendar entries from my Outlook.com calendar. The calendar is listed on the left, along with the other calendars I track (which are Google and non-Google), but the entries are gone (they're present in the Web-based Outlook.com version).

When I attempt to synchronize the online Outlook.com calendar with the Lightning version, the following message now appears in the TB error console log:

[calICSCalendar] Unable to load stream - status: 2152398878

This appears to be a DNS server issue (unknown host). When I paste the .html and .xml sharing links for my calendar into the address bar of a browser (IE or FF), I get error messages that the page can't be displayed or FF can't find the server, respectively.

I've uninstalled and reinstalled TB, Lightning, and Provider for Google Calendar. I have the most up-to-date versions of the browsers. I've re-created the .ics link on the Outlook.com site. My internet connection method hasn't changed. Any other suggestions? Of note, I'm not having this problem on my Android 2.2.2 phone.

Thanks in advance!
