I have seen some very difficult problems answered in here. Hopefuly this is an easy one and I am just missing something.
Running Exchange 2003 with Outlook. I have one user whose free/busy times occationaly are not available to anyone else booking appointments. I looked at it this morning, changed how many months were available, and they were were. A few hours later they were gone again. I just went in and changed her settings to update every 1 and only publish two months and it is once again available for everyone else, but I have no idea for how long.
