A support document describing new premium Outlook.com features for Office 365 subscribers hides the real story today: Microsoft just killed Outlook.com Premium.

I wrote earlier about how Microsoft was bringing some Outlook.com Premium features, like an ad-free inbox, to Office 365 Home and Personal subscribers. That’s great news, of course. But a related support document buries the lede.

“The Outlook.com Premium standalone offering is now closed to new subscribers,” the support document notes. “Current subscribers can renew their subscriptions to continue receiving subscription benefits.”

Yikes.

There’s also a link to another support document that continues this conversation. But there really isn’t much more to say.

If you’re already using Outlook.com Premium, you can continue to do so. And for now, at least, you can even renew the subscription and keep using its unique features, like custom domain support.

“We will continue to support current Outlook.com Premium customers with a custom domain,” the support document notes. “Just continue to renew your Outlook.com Premium subscription, and your domain renewal will be automatically included in your yearly subscription fee.”

Longer term, it looks like Microsoft will eventually get rid of this service, however.

“We’re working on a solution that will enable you to transfer your domain to other providers,” Microsoft explains. “For now you should continue to renew your Outlook.com Premium subscription to retain control of your domain and to continue using your personalized email address.”

And if you did not sign-up for Outlook.com Premium, you no longer can do so. That’s all she wrote.

And… that sucks.
