Sorry, we are unable to verify your email@example.com subscription, so most of your mailbox features have been disabled. Please re-enable now.

Why it happens
While you don’t need to be online at all times to use Office 365, you do need to connect to the Internet intermittently so Office 365 can verify that your subscription is still active. If Office 365 can’t check the status of your subscription for an extended period of time (usually around 30 days), you’ll see the ”Unable to Verify Subscription” message, and Office 365 will eventually disable most of your mailbox features.
