Out of Office Not Working - Exchange 2007

A company had Exchange 2007 SP1 installed in their environment. When users went to access out of office via Outlook they received the following message:

Your Out of Office settings cannot be displayed, because the server is currently unavailable. Try again later.

Users were not getting this message via Outlook Web Access. They were able to change their Out of Office settings via OWA however the settings were not "sticking". Although it said it was enabled in OWA, it was not actually working! Users that currently had it set were not able to disable it...

This problem resides on the client access server role - a problem with the availability service.

In this instance we fixed this issue by installing Exchange 2007 SP2. To do this:
• Install the Exchange 2007 SP2 Schema Extensions (Requires Enterprise Admin and Schema Admin permissions)
• Install SP2 on the Client Access Server
• Install SP2 on the Hub Transport Server
• Install SP2 on both mailbox servers
• Install SP2 on unified messaging server
• Install SP2 on edge transport server

This issue is caused by a problem in the package. This problem only occurs when the package that contains the .NET Framework 3.5 with SP1 and the .NET Framework 2.0 with SP2 is installed on an Exchange Client Access server. This problem only occurs if you are running Exchange 2007 SP1. If you do not want to upgrade your Exchange Organisation to SP2 you can get around it by using a hotfix. Please see:
