Question : OWA 2007 time zone issue

Have a client running Exchange 2007 with all the current updates and DST patches.  A user in the eastern time zone enters an all day appointment in a public folder calendar.  It appears fine in her OWA.  A user in central time then opens the public folder calendar and that event spans across two days.  Ive verified the time zone settings in OWA and the local computer are set properly.  Ive done quite a bit of research and the only thing I found was a workaround to not use all day, set a specific time like 9-5.  Any ideas?

Answer : OWA 2007 time zone issue

This is absolutely correct. Not using the all day event option would also fail sometimes.This problem is related to outlook more than exchange server or OWA. This is a little complex to explain but I will try.

When user A in eastern time books the calendar for a span from 11:59:59 AM to next day same time it looks correct in his/her own calendar because outlook will show it for a whole day. But, when the recipient or the attendee (user B) in another time zone recieves this appointment and accepts it, it is added to attendee's calendar. Now, for user A 12:00 AM to 12:00 AM works fine his calendar but when User B looks at own calendar it spans because of the time difference of 1 hour or so. So, 12:00 AM in CST would be around 01:00 AM in EST outlook thinks that the time specified in the meeting request should be shown as it was marked by the organizer. and spreads it across two days 1:00AM today to 1:00 AM next day and hence it appears spanned across two days. I hope that explains it. If you did not find it satisfactory do add a comment. I will try to rephrase it again.
