So this is neat. In Standard Central Time, US. We have exchange 2003 SP2 with (I think) all updates to date. Outlook 2010. And when we accept calendar meeting invitations on SOME iPhones, it changes the time to 1 hour later immediately after you accept the appointment.

We have tried different versions of the iPhone software and different service pack levels of Outlook 2010. It stays with the user/phone regardless.

It seems to be some bug with the 2007 changes in Daylight savings. We've checked settings on PCs and iPhones to adjust for the new daylight savings and it appears everything is up to date.

How can this happen on some iPhones that are the same model and OS update level and not others?

Definitely sounds like DST update issue.

Can you make sure to apply the updates to the Exchange Server and the client machines as well.

Well it blew my mind because half of the iPhones worked fine, all blackberries and outlook clients worked fine... but there is an Exchange patch we found that somehow didn't get applied. It's KB926666, and we found it by updating the Windows Update to Microsoft Update on the Exchange server.

Thanks for helping me find this. I assume this must fix the problem, but we won't apply the patch till tonight, so we won't know for sure till tomorrow.
