I used the demo and that was very helpful and we got the Exchange tool both V1 and V2 to run ok. But even though it ran it did not fix the calendar appointments as anticipated. It only provided one log file for a user instead of the 11 expected and said it fixed one appt. so we then logged back in under the user and the time did not change. We tested the manual tzmove.exe outlook tool and that did show that it would fix the appts that the exchange tool missed but with several hundred users this is not the preferred method. Will there be any updates to the exchange tool? Any suggestions we can test in our lab to get the current exchange tool v1 or v2 to fix the appts.
