I have a user that when creating a new meeting, and she tries to use the Scheduling Assistant, she is unable to see the free/busy information of the rooms, or even her other co-workers. When she adds the room or another invitee, instead of seeing the free/busy information, she get diagonal lines and a when she hovers over the lines, she gets "no free busy information can be retrieved. Your server location could be determined".
I have ran the cleanfreebusy switch on outlook, recreated her profile, put outlook in cached mode disabled. I even ran powershell script to make sure she had rights. In fact she is in the In Policy settings for the rooms. She is using Outlook 2010, and our Exchange is 2010. She is the only one having that issue.
