iOS 11.0.1 fixes Exchange and Outlook send email issues

iOS 11 has only been out a week, but we already have update 11.0.1 available for download. The minor patch apparently fixes email issues users were having when trying to send emails from their Apple devices.

According to an Apple support page, "if your email account is hosted by Microsoft on Outlook.com or Office 365, or an Exchange Server 2016 running on Windows Server 2016, you might see this error message when you try to send an email with iOS 11: "Cannot Send Mail. The message was rejected by the server." The new update will now allow emails to be sent.
