Less than 24 hours after the official launch of iOS 11, the first unpleasant "surprises" began to appear.
Many users complain that after updateFrom site iOS 10 la iOS 11, I can no longer send emails from the application Email a iOS 11, if the services are used Outlook or Exchange (by Microsoft).
Can not Send Mail. The message was rejected by the server.
This issue was known since the beta testing of the new operating system, but it does not seem to have been resolved until the release of the final version for the public.
Apple says that this error is only encountered by users who use addresses of Outlook.com, Office365 and other mail accounts that are hosted on Exchange servers but by Microsoft. When trying to send an email from these accounts, the Mail application iOS 11 reports the "Cannot Send Mail" error.
In a statement posted by Apple, the company says it is "working closely with Microsoft" to resolve this issue, and as a workaround, urges users to iPhone and iPad that use accounts on Microsoft servers, to send mails via internet browser (Safari). At the same time, Microsoft has in App Store and the Outlook application, which allows authentication to Exchange accounts. This should resolve the error and stop sending emails.
The solution will come in the form of a update de iOS 11. Most likely, in the next few days we will receive a update la iOS 11.0.1 or a similar version.
