Hello
We have another company subletting space in our office. To make life easier with booking meeting rooms etc, I published our office calendar (an Exchange 2010 on-premises public folder) via calendars.office.microsoft.com, using my Microsoft Live ID and Outlook 2007. I got the office manager at the other company to set up a Live ID so that she could have access to this public folder. So far so good, everything worked as planned.
HOWEVER..
All of our users were suddenly and repeatedly prompted for a Windows Live ID ("Please enter your username and password for publishing calendars to calendars.office.microsoft.com"). Major headache. So I right-clicked the public folder > Publish to Internet > Remove from Server. I thought that would kill it, but all my users are still being prompted for their credentials. If they go into Tools > Account Settings > Published Calendars, the calendar is listed there. If they remove it, it returns the next day.
Help!
