After .NET Framework 3.5 service pack 1 is installed on Exchange Server 2007, Out of Office Assistant stops working for Outlook 2007 and Entourage, Test-OutlookWebServices crashes and Scheduling Assistant crashes on Outlook 2007 clients
Details (expand)
Product Language
English

Version

.NET Framework 3.5 Service Pack 1
Operating System
Windows Server 2003
Operating System Language
English (US)
Steps to Reproduce
.NET Framework 3.5 SP1 successfully installed on two Exchange Server 2007 SP1 (with Rollup 3) on Windows Server 2003 R2 SP2 x64 and one Exchange on Windows Server 2008, all previously fully functional. All Outlook 2007 and Entourage 2008 clients affected.
Actual Results
Outlook 2007 Out of Office Assistant reports "Your Out of Office settings cannot be displayed, because the server is currently unavailable".
Test-OutlookWebServices crashes after contacting autodiscover with ""WARNING: an unexpected error has occurred and debug information is being generated: Object reference not set to an instance of an object. At line:1 char:24 + test-OutlookWebServices <<<< | fl". Event log: ""EventType e12, P1 c-rtl-amd64, P2 08.01.0240.006, P3 powershell, P4 m.e.management, P5 m.e.m.s.availabilitytest.validate, P6 system.nullreferenceexception, P7 4ab8, P8 08.01.0291.001, P9 NIL, P10 NIL."
Typing an alias into the "All Attendees" list in the Scheduling Assistant causes an access violation in Outlook 2007.
Expected Results
Everything worked until .NET Framework 3.5 SP1 was installed.

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!

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:
