Hi nwbergman,
Thanks for your post.
I’d like to confirm what do you mean by saying “new and improved” microsoft365 platform?
Do you refer to Office 365 Small Business Preview?
If so, if you find your rebuilt website isn’t available, we
recommend you to check if your website is set offline: log in to your Office
365 Preview portal, and click Sites
> Public Website, then in the top header, you can know whether your website
is offline.
If the site is offline, it means it hasn’t been allowed to
show online. Click WEBSITE OFFLINE > MAKE WEBSITE ONLINE > Continue > Make Online, then the site can be reached by
public.
Thanks,
Ella Huang
