Hi,

this workaround works for me:

  • uncheck default html-format on both composing (preferences) tabs
  • detto for format of org message

the drawback: the message is plan text formatted, but included.

I’m eager to hear back and work together to find a solution.

Same problem here.
This is being analysed by Microsoft to fix it in a next update

Meanwhile I changed to non Legacy Outlook version and I don't have the problem anymore.

    In Outlook, replies normally include the original message text by default. If the original content is missing when replying, the reply/forward settings are likely configured to not include it.

    To change this behavior (example from Outlook for Windows, which controls how replies and forwards handle the original message):

    1. Select File > Options.
    2. Select Mail.
    3. Under Replies and forwards, for When replying to a message choose one of:
      • Include original message text (default), or
      • Include and indent original message, or
      • Prefix each line of the original message, or
      • Attach original message.
    4. Select OK to save.

    Avoid Do not include original message, because that removes the original content from replies.

    If the issue is that messages in a thread are disappearing from the Inbox or going to Deleted Items after replying, check that the conversation is not being Ignored:

    1. Open the Deleted Items folder.
    2. Select a message from the affected thread.
    3. On the Home tab, in the Delete group, select Ignore.
    4. When prompted, select Stop Ignoring Conversation.

    This moves the conversation back to its original folder and stops future messages in that thread from being automatically deleted.
