Recently, original message header is lost when replying or forwarding emails in some Outlook mails.
It is strange that some emails retain the headers with time stamp etc. Some are gone.
Seeking help for this very important function...How to fix this?

    Problem finally appears to have been resolved in version 16.53 released today. Hurrah!

    See above by nzbloke...
    "The problem is the incompatibility of the two options under Composing:

    • Custom attribution format
    • Compose messages in HTML by default."

    I just did this under both the HTML and Plain Text tab in Outlook and the headers appeared on email relies that I "know" didn't have them before. It wasn't gmail related for me -- unless the businesses whose email replies failed to include the header were actually gmail addresses. I had gmail addresses that worked just fine.

    The failure to include was consistent with particular senders -- it never included them -- not just sometimes.

    Will report again if this changes.

    Same issue. Macbook Pro 13" , Big Sur 11.5.2 , Outlook 16.52, gmail emails.

    This is eating up a ton of time . . . Please fix this bug.

    Same problem as well!!. mostly notice on IMAP accounts and replying to Gmail senders.

    Only since updating to latest version of Outlook on Mac.
    Outlook: 16.52 (21080801), using 'classic' version (IMAP!)
    OS: Catalina 10.15.7

    Same problem here since updating to latest version of Outlook on Mac.

    The issue doesn't seem to be related to mail services but to the HTML content of the original message. Using the same IMAP service, some messages do include the header when replied to, other messages consistently result in a 'naked' reply. I am sure the bug has been introduced when I updated Outlook for Mac.
