How to include all email chain in reply emails on Mac Outlook App

Hi Kajg

Based on your description, Outlook for Mac should normally include the original message and previous conversation when you reply to an email. If this behavior changed after a recent update, it may be related to either a setting change or a version-specific issue.

In New Outlook for Mac, please check: Outlook > Settings > Composing. If available in your version, review the "Attribution of original message" setting and ensure it is configured to include the original message information when replying.

To help determine whether this is an expected behavior or a potential issue introduced by the update, could you please provide:

• Your Outlook version (Outlook > About Outlook)
• Whether the entire previous email chain is missing, or only part of the original message is missing when you reply

Additionally. there have been some reports from some Outlook for Mac users that changes in recent updates can affect how original messages appear in replies, so the Outlook version will help narrow down the cause. You can refer to: Legacy Outlook for Mac is now removing history when emails are replied or forwarded - Microsoft Q&A (for Legacy). If the issue began after a recent update, you might consider temporarily rolling back to an earlier version of Outlook as recommendation in this thread to check whether the behavior changes.

You can install the earlier version of Outlook from this link: Update history for Office for Mac - Office release notes | Microsoft Learn 

However, if you are using a device managed by your school or company, there may be situations where you need to contact your IT administrator to help you roll back to an earlier version.

I hope this information helps and look forward to your response.
