Update: This issue has been corrected with the iOS 11.0.1 update. To fix the issue, update to iOS 11.0.1 or later.
Apple has published a notice about sending an email with the new iOS 11 and an Outlook.com or Exchange email account. As SMU uses Exchange and Office 365 for email, we are asking the SMU Community to delay installing the latest OS on your mobile device until an update is available.
The original notice from Apple is below:
If you can’t send an email with iOS 11 and an Outlook.com or Exchange mail account
You might see an error message that says “Cannot Send Mail. The message was rejected by the server.”
If your email account is hosted by Microsoft on Outlook.com or Office 365, or an Exchange Server 2016 running on Windows Server 2016, you might see this error message when you try to send an email with iOS 11: “Cannot Send Mail. The message was rejected by the server.”
Apple is working closely with Microsoft to resolve the issue and will release a fix soon in an upcoming software update.
If you have concerns or questions, please contact the IT Help Desk at 214-768-HELP or help@smu.edu.
