@rothja @craigg-msft - I'm not finding the author Grace Gu in Outlook. Is she still the author of this article? Is someone on your team available to look at this PR? Thanks much.

[rothja]

@ktoliver Yes, you should be able to reach out to Chunhua Gu in Outlook. @chugugrace Can you take a look at this pull request and the changed files and see if you approve? FYI @craigg-msft.

Thanks @rothja

@chugugrace - I am surprised this is taking a minute to be approved. I have developers relying on references to ms docs and accuracy makes the world a much better place :)

[rothja]

@wase932 Sorry for the delay. I'm going to reach out to them internally to see if we can get this looked at.
