Question: Is SP2a still supported?

I was planning to install the Out of Office component in a production environment. Since I downloaded the component several months ago, I did not realize that a SP3 and an Out of Office SP3 has been realeased. I am considering deploying the OOO SP2a version locally, since the SP3 install has given me an issue/problem that I need to research. (I will probably post the error in a separate post).

Thanks.
