    Hi,

    Looks like there's an issue if you upgrade to iOS11. Anyone who connects to an Exchange 2016 server or Office 365, won't be able to send, forward or reply to an email, they'll get an error saying the message was rejected by the server.

    To fix this, head to the mail account in Settings and re-enter the user's Exchange password. Hopefully they'll patch this before the storm hits.

    I've had this problem. Usually, re-sending the message from the Outbox resolves it. I'll try to re-enter the password in hopes that fixes it. That does seem to resolve the problem, at least for one email. Thanks.

    having the same issue. Seems to be related to attachments - emails without them are sent ok as far I can tell

    I was getting rejected by server errors even without attachments. I hope this gets sorted out very soon.

    I had no issue with the GM from the Beta program.

    A phone reboot fixed it for me. Had this happen today as well as a few weeks ago.

    Are you kidding? Major iOS release and it breaks the email that is most common for business users?!? They need to get this resolved today.
