I have a user who is on a PC and her supervisor is on a Mac. She is set-up as his delegate. When she makes a time change to a meeting on his calendar, the meeting changes. When she looks at it a few minutes later, it is back in the original time viewed on her PC. However, it is in the correct time when viewed from his Mac. Her supervisor was put on the Mac just a week ago. As you can imagine, this is very frustrating for her when planning his schedule. Any help would be appreciated.
