Apple Releases iOS 11.01 to Fix Exchange Bug

Apple today issued a small update to the millions of iPhones and iPads that have already upgraded to iOS 11. It fixes an Exchange connectivity bug in that release.

“You might not be able to send email with an, Office 365, or Exchange account until you update to iOS 11.0.1,” an Apple support document notes.

The bug impacts email hosted by Microsoft on or Office 365, or Exchange Server 2016 running on Windows Server 2016. You’ll know you have the problem if you see the error message “Cannot Send Mail. The message was rejected by the server.”

As with all iOS updates, iOS 11.0.1 will be offered to you automatically. But you can install this update immediately by navigating to Settings > General > Software Update.

Oddly, I’m not seeing the update at the moment, so I’m wondering whether the update is being phased in. Or if you won’t see this update unless you actually configure an Exchange-type account in Settings > Accounts & Passwords.

Thanks to Robert B. for the tip.
