iOS 11.0.1 Fixes Mail Bug with Microsoft-hosted Accounts

Apple has released iOS 11.0.1, merely noting that it has “bug fixes and improvements.” However, in a separate note, Apple says this update resolves the issue with Microsoft-hosted email accounts detailed in “iOS 11 Mail Failing to Send with Microsoft-Hosted Accounts” (22 September 2017).


You can get the iOS 11.0.1 update, which is roughly 275 MB, in Settings > General > Software Update or via iTunes.

Those who were participating in the developer beta of iOS 11 may need to delete the iOS beta profile in Settings > General > Profile and restart the device to get iOS 11.0.1 to show up.
