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.

    You need to delete the beta profile to get the update. I had the same problem

    Just more evidence that Apple isn't God's gift to well-executed implementations. It's not that Apple is unique with regard to having such problems, but rather that it's not unique with respect to avoiding them.

    I delayed installing for this exact reason. I knew more updates are coming.

    I see the update on my iPhone 6s, but not my iPad mini 4.

    This bug, at least amongst our customers, has helped Microsoft with adoption of Outlook Mobile immensely.

    Still holding off from updating to iOS11. Too many bugs that need fixing.

    Updating took 40 minutes instead of a usual 15 for a minor update.

    One fixed bug: the Files app does not freeze on deactivating a source.

    I need more testing to see if two other iOS 11.0 bugs have been fixed.

    All other bugs I am aware of are major and related to the Files app. The worst of all still existing bugs: „my own iPad“ is not shown at all so I cannot handle any file in Files, which is promised to be the central file manager for all files. If this should not be a bug but a feature, Apple would have lied about the functionality of Files and commited the greatest mistake since the initial omission of file management when iOS started.

      It’s a bug. I had the same issue and contacted Apple support. The solution is r ally easy. Select a file, pick the option to move it. The “My IPad” or what it is call will show up as a location, move the file there and it will start showing up as a location on the left. Then just move the file back.

        Many thanks! I have had to make a serious effort to achieve what you suggest but now „On my iPad“ is generated for the first time.

        I have succeeded to circumvent the bug as follows: update the apps LiquidText and Documents to their iOS 11 compatible versions. In Documents, share its manual with LiquidText. In Files, for the source Documents, create a new folder. In Files, click on the notification of a new source and select / activate „On my iPad“. I am not quite sure if this has been exactly my procedure but with some such attempt Files is motivated to offer „On my iPad“. Before, my attempts with the iBooks and Photo apps have failed. Apparently, some related minor bugs still need fixing. Anyway, only now I can start exploring what Files can or cannot do as a file manager.

    We shall see if the battery issues were fixed as well, it seems odd the patch is so large for just one "bug".

    I find it facinating that the title of this article touts this a a bug in Exchange and not a bug in iOS.

    This bus is fixed now. Its not present on iOS 11.1.1 & iOS 11.1.2 versions. You can use Filza file manager app to get root access on your Android and iOS devices using Filza file manager.
