Product: Microsoft Outlook for Mac

Description of the issue: After updating Outlook for Mac [Version 16.110 (26061317)] on 18/6/2026, replying to any email no longer includes the original message in the reply window. Prior to the update, replies correctly contained the original email text below my response.

Steps to reproduce:

Open Outlook for Mac.

Select any received email.

Click Reply.

A new reply message opens.

The original email content is not included in the reply.

Expected behavior:

The original message should be included in the reply, as in previous Outlook versions and according to the configured reply settings.

Actual behavior:

The reply window contains only a blank composition area (or only my response), with none of the original email text included.

Additional information:

The problem started immediately after the latest Outlook update.

  • The issue occurs with all emails tested.

The problem did not exist before the update.

  • Restarting Outlook or the Laptop do not resolve the issue.

System information:

  • Outlook version: [Version 16.110 (26061317)]
  • macOS version: [Apple M3 Pro]
  • Legacy Outlook

Impact:

This issue significantly affects email workflows because replies no longer contain the context of the original correspondence.

    I think this type of thing is outrageous especially when there seems to be no urgency to fix the issue. A multi-national company with billion dollar annual profits should not be making these sorts of errors (if they are errors) without pulling their finger out and resolving it when they are reported. Lots of people are now paying for something that doesn't work and that isn't right. Ironically, I had only just switched automatic updates back on from a previous Microsoft balls-up that prevented me from working properly. My MacBook was left on manual updates and that is fine but my iMac isn't. Come on Microsoft! With all those profits and so called expertise, you should easily be able to roll out a patch for this....or will that eat into your profits for this year too much?

    I deleted Outlook from my Applications and then reinstalled the 16.109 install package, and now it works. And I have not lost any of my settings, which was the part I was most afraid of. Thanks @Jayden-P for the instructions. I also have automatic updates turned off for now (lesson learned!!!).

    Hi @Tsoumpas, C (ngmb)

    Thanks for reporting this issue. Microsoft is aware and actively investigating this behavior.

    Replying to or forwarding an email does not include the original message in the email body in legac…

    I have tested on previous version such as 16.109.3, and this behavior does not occur. Therefore, you may consider reverting to version 16.109.3 or older. This can be done by removing the current Outlook version and installing version 16.109.3 via Update history for Office for Mac - Office release notes | Microsoft Learn

    After that, turn off automatic updates for Legacy Outlook for Mac by going to Help > Check for Updates > unchecking Automatically keep Microsoft apps up to date. 

    I apologize for the inconvenience this might have cause to your workflow, please revert back to previous version as a temporary workaround.

    I will keep you updated if there's a fix for this. Thank you for your understanding and patience.
