Access to resource denied; Outlook 07 Calendar problem

My husband & I regularly publish & share our calendars so we know we're both doing. It's a great feature in Outlook 2007. However, during the past week I have had this message displayed while in Outlook: "Access to the resource was denied. If you have signed into and saved your Windows Live ID with a Web site, sign out of that Web site, and then try this operation again." There is also a send/receive error: "Task "Internet Calendar Subscriptions" reported error (0x94972eed): Cannot verify or add the calendar to Outlook. Make sure the following is a valid calendar link: webcals://calendars.office.microsoft.com/pubcalstorage/[id number]/[husband's name]"

To add insult to injury there is another annoying Windows Live ID sign in box that periodically pops up with my user name & asking me to put in my password. Of course, when I do it it just comes up again.

Naturally Microsoft has a supposed solution for IE, but I can't find anything on their website for FF.

Help!!!

Ok... No joy here.

BTW, the problem resolved itself. Apparently, there was a problem with the calendar updating service on MS itself. The next time my husband uploaded a new calendar & I dl'd/shared it I no longer got the "error" msg.
