I am using Outlook 2011 for Mac. Some of my office mates use Mac and some use Windows and our server and exchange are both Windows. Two office mates (both mac users) gave me permissions to view their calendars. The next day, I found that I could only view one of the calendars. I tried to open other user's folder but it tells me she must give me permission. She has reset these to give me permission again but it still doesn't work. I still have the option to add her name to the 'from' field of outgoing emails but I cannot open her calendar. Does anyone know why Outlook would drop some of her permissions for me? Thanks, Laura

Hello, How about assigning the permission by the following steps in Outlook (not Entourage): 1. Open Outlook, click Tools >> Options. 2. Click Tools >> Options. On the general tab, click Calendar Options. 3. Click “Free/Busy options”. 4. Click ADD and add the permission level as Owner. What’s the Exchange version do you use? Thanks, Simon
