Email Signatures Not Working on Replies

Question

Email Signatures Not Working on Replies

BC 5

I use a Macbook with Outlook installed. I have had no issues before yesterday. Signatures on reply emails are now put at the very bottom of the chain rather than where you type a reply. It is doing this on all four accounts I use in Outlook.

I deleted the signatures and changed the rules to none for new and reply and restarted the computer. I added the signatures back and nothing has changed.

I can confirm that BC is not the only user experiencing this issue.

I am currently having exactly the same problem with Outlook for Mac, version 16.112.1 (26081720).

When replying to an email, the signature is incorrectly inserted below the original message header (From / Date / To / Subject) instead of directly below the new reply. The same thing happens even when I try to insert the signature manually.

The issue appeared suddenly and, at the same time, Outlook has also become very unstable: it frequently freezes, I sometimes have to force quit and restart the application, and even simple actions such as deleting drafts can fail.

This therefore seems to be an Outlook for Mac client issue rather than an individual signature configuration problem.

It would be helpful if Microsoft could investigate this as a possible regression in the current Outlook version.

Hi Le Concept Admin,

Thank you for sharing that additional information. Since another user is seeing the same behavior on Outlook for Mac version 16.112.1, along with application instability and freezing, this does help suggest the issue may be related to the Outlook client environment rather than a specific signature configuration.

As a quick way to narrow things down, could you check whether the same signature placement issue occurs when using Outlook on the web (via a browser)? If signatures appear correctly there, it would further indicate that the behavior is isolated to the Outlook for Mac application.

Exactly the same has been happening on my Outlook for Mac since around the same time. Nothing I try fixes it.

You will probably not get any help for your issue by adding to an existing post. I would suggest that you start a new thread using the "Ask a question" button at the top of this page to create a new Question and include the details for your specific problem. This provides much higher visibility to your issue than adding on to an existing post, which is only seen by people who are already following this question.

Signatures on replies are at the very bottom of the chain

I am tracking multiple reports of this problem:

Only possible workaround I've seen is from:

https://techcommunity.microsoft.com/discussions/outlookgeneral/outlook-for-mac-inserts-signatures-at-the-very-end-of-an-email-chain/4460566

enabling “When replying or forwarding, use the format of the original message”, is currently the best solution, as it forces Outlook to keep the proper layout. Microsoft is aware of the issue and is expected to release a fix in a future update

Submit a Problem Report

Every report helps move this issue one tiny bit higher on the Microsoft Fixit List. (I can imagine it's a pretty long list).

How to Submit a Problem Report:
See the "macOS" tab at https://support.microsoft.com/en-us/office/how-do-i-give-feedback-on-microsoft-365

Copilot suggest this as a sample Problem Report:

Title: Outlook for Mac: Email Signature Appears Below Quoted Message Header Instead of Below Reply Text
Problem Description: Since a recent Outlook for Mac update, email signatures are being inserted in the wrong location when replying to messages. Affects both automatic and manually inserted signatures. Recreating signatures, restarting Outlook, and recreating the account do not resolve the issue. Multiple users have reported the same behavior in New Outlook for Mac.

I tried the fix of "When replying or forwarding, use the format of the original message" - it doesn't work for me. The signature is still inserted at the bottom of the email chain.

Hi BC,

Since the behavior started suddenly and is affecting all four accounts, it may be worth checking whether the issue is specific to the current Outlook experience rather than the individual signature settings themselves. The thread indicates that recreating signatures did not change the result.

As a quick test, please try:

In Outlook for Mac, switch between New Outlook and Legacy Outlook (if the option is available).
Send yourself a test message and reply to it.
Check whether the signature is inserted correctly in both experiences.

If the signature is positioned correctly in one mode but not the other, that helps narrow the issue to the Outlook client behavior and may provide a practical workaround while continuing to use Outlook normally.

I hope this helps point you in the right direction. Let me know if you need further assistance, feel free to ask me by clicking "Add Comment" or "Add Answer" if you cannot add comment so your response will be visible. Thanks for your effort.

I have the same problem and confirmed that in Legacy Outlook, all the positioning works correctly. This is exclusively with the "new" Outlook and began with some recent update. Because Office Mac doesn't appear to use a conventional Apple Preferences (plist) structure, there isn't a simple way to reset things.

I do hope they fix this soon!

Hi RicG-PDX,

I completely understand how frustrating this must be, especially when email signatures are a standard part of your workflow and the issue appeared without any changes to your configuration.

At this point, there does not appear to be a configuration change within Outlook that consistently restores the expected signature placement. As a temporary workaround, you may consider:

Switching to Legacy Outlook (if available).

Testing replies there to confirm that signature positioning returns to normal.

Submitting feedback through Help > Feedback > Report a Problem and including your Outlook version and a brief description of the behavior.

I realize that this is not the resolution you were hoping for, particularly when the issue affects day-to-day email communication and other users are reporting similar symptoms. Thank you for taking the time to share your findings and compare experiences with others, as that information helps build a clearer picture of the behavior.
