I tried to find the answer in by searching all over and I can't seem to find one matching my problem. The company I work for have an outsourced exchange server but working very well together with Office 2003 client. When migrating the klients to Office 2007 we lost some functionality.

Suddenly in office 2007 the out of office function says the server is unavailable on all office 2007 clients, while all 2003 clients are just working fine as usual. It's the same with booking rooms and seeing how all attendees are available. The status is No information no Free/busy data could be retrieved. However, peoples calendar is working just fine in office 2007 to see availability.

What is the difference in using Microsoft Office 2003 and 2007 client, How do we solve this issue?

    I assume your Exchange server is 2007. If so then there is a big difference with this.
    If Exchange is 2007 then Outlook 2003 connects to the public folders to get the OOF and Free-Busy information but Outlook 2007 used Autodiscover and connects to the Availability service to get the OOF and Free-Busy information.

    Ok, thanks for the information :)
    so how do I use Office 2007 client to work on an exchange server 2003? or isn't it backwards compatible?

    If the Exchange server is 2003 then Outlook 2007 will also connect to the Public Folders for these informations and they should work fine.
