    this is unbelievable.
    I have seen hundreds of people having same problems (yes I am one of them too) and we are like a ping pong balls between the email providers and microsoft.

    All these people are not using only one email provider and it is obvious people are facing this problem only when they use microsoft outlook but microsoft is still blaming the email providers rather than offerring a proper solution.

    No error message occurs unless the email is replied by outlook and I never face with the same problem if I use providers' webmail or if I use any other email client but only microsoft outlook. It is really unbelievable that we are trying to convince Microsoft its their fault.

    Dear Ahmad Altaher,

    This issue is solved for me - I composed a new email then copy and pasted the content from the existing thread.
    .....
    If you want to reply on the same thread , Cut and paste the content ..
    .....
    i think the first solution will work fine...

    Perhaps your issue was triggered for different reasons. In my case if I have a long email chain, I can trigger this error by hitting reply even after removing all attachments and the message body. So I know it's the references header not being adequately split.

    Nothing useful yet...

    After further investigation, the error only occurs when I am trying to send an attachment. It has absolutely nothing to do with the message text itself.

    I'm hoping there will be a fix soon, it's getting very difficult having to use other methods to send attachments.
