Hi All I have been struggling with this for some time, so please help me!!! I am developing a global web application using ASP.NET. I need to get the app to communicate with an Exchange Server (on a seperate server, but in the same domain). The app will set up meetings for several people. Each person could be in a different timezone. Some of the users will be internet users and not on the same domain as the web app and Exchange Server. I think that I have to use WebDAV over HTTP to communicate between the web server and exchange server. I have done some tests, but I can only get the Exchange Server to communicate in UTC and not a local (DST adjusted) time... Is it possible to do this using WebDAV XML requests or do I have to do the timezone and DST adjustment myself? Many thanks for your advice, Kulgan.
When create new appointment (or send meeting request) then you have to specify all dates (StartDate, EndDate) as UTC time. You as organizer of a meeting will convert your local time to UTC time and create appointment. When you (or other users) want to retrieve (read) appointment with Outlook (or OWA) then Outlook will convert UTC time to local user's time. If you develop application with WebDAV to read appointments then you have to convert UTC time to local time and all users will see right time. In this case you do not need to specify TimeZone. Michael ------------------------------- If you need WebDAV API for Exchange server, use our component WebDAV .NET for Exchange.

Thanks for the info. How do people usually deal with this issue? I am developing a global web app with users in different time zones and different DST regimes. Is there a standard toolit that I can buy that will deal with this? Thanks, Kulgan.
