Outlook signature has changed spacing

Brandi Naquin 55

My Mac updated last night and now my signature in outlook has spacing that was not previously there. When I go into the signature tabs to fix this, it appears as normal. How can I change this without changing it every time I create an email?

Same problem here

Outlook for Mac, version 16.106.xxxxxxxx
Mac Tahoe 26.3

I had an empty mail in my concepts, when I add one you can see the difference.

And after the latest update:

It happens with all signatures.

Restarted the Mac, and did an update of Outlook (to version 16.106.xxxxxxxx) but to no avail.

Hi @Richard van Breugel

Thank you for reaching out.

May I confirm whether creating a completely new signature helped resolve the issue on your side?

In addition, you may consider installing an Outlook for Mac version earlier than 16.101.xx. You can find these versions in the Update history for Office for Mac - Office release notes | Microsoft Learn. In my testing, the issue did not appear when using a version below 16.101.xx

I hope this gives you some additional clarity.

I thought I removed enough already, excuse me.

I installed the older version but when starting I always get the latest version, when I remove the latest will all my settings be gone? How to install the old over the new version?

Opening the signatures, copying them and pasting them in a new signature does solve the problem.

But they are not exactly the same...

Hi @Richard van Breugel
Thank you for sharing.

After installing Outlook for Mac with a version earlier than 16.106.xx, please also make sure to disable AutoUpdate.

You can do this by going to: Help > Check for Updates > uncheck “Automatically keep Microsoft Apps up to date.”

Regarding copying and pasting the signature, some formatting elements may not transfer perfectly. Certain layouts, spacing, and styling may require manual adjustments to recreate the original look. Copying and pasting alone may not always reproduce the exact formatting.

I hope this helps provide additional clarity.

I cannot install the older over the newer, the newer stays the default app.

Do I need to remove the newer one first? What happens with my settings?

Hi @Richard van Breugel
To install an earlier version of Microsoft Outlook for Mac, you will need to remove the currently installed version first.

You can do this by going to Finder > Applications > Microsoft Outlook > right‑clicking it > Move to Trash.

Once the current version is removed, you can install the earlier version by running the updater.pkg file from the version history notes. After installation, make sure to turn off AutoUpdate to prevent Outlook from updating again.

I hope this provides additional clarity.

Go to settings. Delete current signature(s). Then re-create your signature and it will resolve.

Same problem here. Very frustrating, and the suggested solution is "use an old version and turn off auto-update 😂"

As another commented has said, copying the signature, creating a new one and pasting it in has solved the issue for me.

Same problem here. Our email signature is centrally handled by Xink.io
I looked at the signature in backend in HTML, and noticed every line break was marked as a paragraph instead of a regular break.
I had a chat AI clean it up and replaced the code in the online backend.
Solved it for me

This was annoying me tremendously for the last few months. I just figured it out. When you want a new line in your signature, do not press Enter (for Windows PC) or Return (for Mac). Instead, press Shift+Enter (for Windows PC) or Shift+Return (for Mac). This will also create a new line but for some reason this eliminates the extra space when pasting the signature into an email. Weirdly, as others noticed, pressing Enter or Return will not show extra space in the signature editor, but will add the space when adding the signature to the email. It does not make any sense. Signatures are so common and it's strange that a supposedly good company like Microsoft would have such an idiotic bug in the system.
