Can't set work time in OL 2010, all options are grayed out. Using Windows XP Pro in an AD environment. After OL 2010 was first installed, I was able to set it, now my work hours are back at the default (7 to 7) and I can't make any changes as every option is grayed out. I have a co-worker who set his, it is still set at what he set it to but his is also grayed out. He cannot change his either. OL/File/Calendar/Work Time (Path to options). Anyone know why this may have happened?
