iPhone Mail email intermittently truncated when replying or forwarding, so the email thread is missing

Office 365 and Exchange 2013/2016 users are getting intermittent truncated emails when replying or forwarding. This is affecting iOS 12 and 13 and all iPhone and iPad models. If the user doesn't notice the problem before sending the receiver only gets the header of the reply but no text body or previous threads. There is no root cause but it appears to be worse when the sender is on cellular and/or gets a lot of emails constantly and replies quickly. Please notify Apple if you're having this issue and encourage them to make a public posting about this issue. It appears to have started or gotten worse on or around October 4th

iPhone 11 Pro Max
