iOS: Having some trouble sending an office email on your iPhone? You downloaded iOS 11, didn't you. Sure, it has some dope upgrades inside, but it's also the first version of the new operating system, and that means bugs. True to form, a software issue in iOS 11 is preventing Exchange email servers from sending and receiving messages, affecting Outlook, Office 365 and Exchange Server 2016 users. The good news is that Apple's latest iOS update, 11.0.1 fixes the issue, along with some other unspecified bugs.

iOS: Having an elaborate, secure password on your Wi-Fi network can be a great thing. A great thing until that weekend you have guests visiting from out of town and they have to try your 20-character Wi-Fi password a dozen different times because a zero looks like an O or they couldn't tell from your chicken scratch which letters are capitalised and which aren't.
Users of the Microsoft-hosted email services were greeted with the message "Cannot Send Mail. The message was rejected by the server" after downloading the first version of the new iOS. Not a great feeling, to be sure. Apple has since addressed the issue in a support page, where it tells users to upgrade to iOS 11.0.1. We generally recommend performing software updates through iTunes and a wired connection, but visiting Settings > General > Software Update will also let you update the OS from your device.
While it probably did fix a few bugs, and Outlook and Exchange users can send emails again, iOS 11 still feels a bit unpolished. App rearranging is a buggy affair, and essential shortcuts in the updated Control Center aren't as useful as they once were. If you've been holding out until the first bug-fixing update, then go right ahead and upgrade your device. Just check to see if it's compatible first. Don't want you to get your hopes up.
