Outlook.com, Office 365, and Exchange Server 2016 users can not send emails in the official Mail app that Apple delivers into iOS 11.
That report Microsoft Wednesday after Apple released the update for the iPhone and iPad operating system available Tuesday suggested.
It is not clear what caused the problem. To the best of my knowledge, there were no problems during the beta period of iOS 11.
Outlook.com users – former Hotmail and other Microsoft services may receive emails. Only when sending is a message that an e-mail is “denied by the server”.
As a solution, Microsoft suggests for the time being that people download the Outlook app from the App Store. The company works with Apple to solve the problem. It is not known at what time it will take place.
