I was able to create an exchange account on my wife's Tab, and the calendar events from her MS Exchange account download fine, but we are unable to edit them. If we add an event from the Tab, we cam edit, but if she changes the event from her work computer, the event becomes un-editable again. I saw this posted elsewhere as a problem, but there was no solution. BTW, this only happens with the stock calendar. We can edit fine with Pocket Informant. Anyone have a solution?
