Sorry, forgot that my branch of OpenChange was that far ahead of the core
project and that this code was actually added by me a few years ago.

My branch is at https://github.com/mmcculligh/openchange.  Since the core
project seems to have been abandoned I've stopped creating PRs to merge
these changes.

That would seem to work.  If you have a specific place in mind I can make
the change and test.
