We are on 10.7.2 and
Exchange: 2007 SP3 RU4
Here are the behaviors we are experiencing on more then one client.
New event creation issue where new events would not save correctly to exchange server:
In my case I was simply creating new appointments by double clicking on iCal and setting date and times. The 'new event' issue would occur intermittently among the other issues of events disappearing on refresh. To me it seemed like there was just an issue with iCal updating to the exchange server. Depending on the timing, it would update/sync and the iCal event would do one of three things…
1.) It would be in the correct place, at the correct time, with the correct name (that day, very rarely would it stay where I wanted it…since then though, it has been much better).
2.) It would no longer be on the calendar at all, as though exchange never saw any calendar event when it synced, and instead synced an empty calendar over the event time.
3.) It would go halfway…which is it would have an appointment listed, at the time that I double-clicked on, named New Event…but wouldn't have the proper name or the date/time I might have changed it to.
Drag and Drop Issues:
If you do things to fast(especially with drag and drop) you can lock up iCal and the changes which you want to make do not get passed to the server. When you relaunch iCal you do not see the changes made.
If you quit too fast after making a change I've seen it where changes do not get passed. This should correct with the relaunch of iCal however this is sporadic at best.
I have not seen or been able to reproduce the instance where when you set up a new meeting that it never makes it to the calendar or gets reverted back to being a New Event.
As we are in an enterprise environemnt there are higher ups who are just not happy about losing appointments this way.
Is anyone else experincing this.
