I faced the same issue which remained consistent even after I uninstalled .NET 3.5 SP1.
So when I installed all the three files in the required sequence, the GetUserAvailabilityResponseType started working as expected.
Please see the Knowledge Base Article KB959209 for more information.

Please download and install all 3 updates available in the section titled Files in This Download. These updates should be installed in the following sequence: [ http://www.microsoft.com/downloads/details.aspx?FamilyID=98E83614-C30A-4B75-9E05-0A9C3FBDD20D&displaylang=en&displaylang=en ]

1.    Install the update for the .NET Framework 2.0 Service Pack 2 - Windows6.0-KB958481-x64.msu
2.    Install the update for the .NET Framework 3.0 Service Pack 2 - Windows6.0-KB958483-x64.msu
3.    Install the update for the .NET Framework 3.5 Service Pack 1 - NDP35SP1-KB958484-x64.exe

Hope it helps!

Hello-

Thank you for reporting this issue. This is a known product bug that shipped .NET 3.5 SP1.

However, we have provided multiple different ways for you to obtain this fix:
-KB article is located here: http://support.microsoft.com/kb/952883

- The fix has been shipped in the .NET 3.5 app-compat update. If you have Windows Update enabled, this fix will be automatically downloaded. If you can download straight from the following location: http://support.microsoft.com/kb/959209

- This will be fixed in Vista SP2 and onwards

I appologize for any inconvenience this has caused you. Please let me know if you have any additional concerns.

I've had the same issue. After installing .NET 3.5 SP 1 I was not able to query Free/Busy time through Exchange Web Service. The FreeBusyResponseArray of the response was null. I wasn't able to query it through outlook 2007 either. I did a full uninstall of .NET 3.5 SP 1 by uninstalling 3.5 SP 1, 3.0 SP 2, and 2.0 SP 2 and then reinstalling 3.5 (without SP 1) and everything went back to normal.

Here's a thread about the problem:
