I've spent a while hunting around for an answer to this one without success. Hopefully someone here can help. In Exchange 2007 when users are sent an automatic message from a resource about a conflict with a meeting they are trying to book the format of the date is wrong. The system uses the American format whatever the Region is set to on the account, client machine or Exchange Server. I'd like to see the messages come in the same format as the server is set to. Example follows. The conflicting dates quoted are in the wrong format: Your request was declined because there are conflicts. The conflicts are: Organizer and Time of Conflicting Meeting UserName1 - 10/26/2012 10:00:00 AM to 10/26/2012 11:00:00 AM UserName2 - 10/26/2012 11:00:00 AM to 10/26/2012 11:30:00 AM All times listed are in the following time zone: (GMT+00:00) Time Zone
