Just a quick note on a little error I had installing OCS 2007. We have a lot of users that are set up to run services for applications - as such we have a fairly tightly controlled group policy regarding the permissions required to run as a service. This causes the error above to occur because the newly created users aren't given permissions to run a service. The solution is to add the newly created users to our Application Service group.

I added the RTCService user after the first installation failed, and ran again. It will fail a second time because the RTCComponentService is not created at the time the RTCService user causes the installation to fail the first time. Add the RTCComponentServiceto the group and it will install without any issues.

It seems that the nice people at Microsoft were looking out for us, lest the evil people in the world see how we categorise our email, and decided to strip away any category information from sent and received objects by default. Sure, I understand if you were categorising emails from someone as "sneaky git" or "numbnuts" then you might not be too happy about sending those out...but really it should be your choice right?

Did you know, for example, that In your Outlook 2007 rules there is a sneaky little enabled by default rule that clears the categories?

Removing that is an obvious first step!

The next step involves editing the registry, so make sure you know what you are doing before editing, always back the registry up first

There are also some registry keys you'll need to add, so open up Regedit and in HKCU\Software\Policies\Microsoft\Office\12.0\Outlook\Preferences, create DWORD keys SendPersonalCategories and AcceptCategories with values of 1. You'll need to restart Outlook for them to apply.

Finally, as per this TechNet article,  log on to your Exchange server as an Exchange Organisation Administrator and run the following command in the Exchange Management Shell

Set-TransportConfig -ClearCategories $False

You should be able to send and receive emails, appointments, tasks and any other Exchange object that supports categories, complete with category intact.
