    Spacing and image behavior in Outlook for Mac signatures has been affected by several recent builds. There are known issues where signatures (including layout and images) are missing or not rendered correctly after specific updates, and these have been addressed in subsequent builds.

    For Outlook for Mac:

    1. After the 16.63 update, signatures could not be created and existing signatures disappeared. This was fixed in build 16.64. Updating Outlook to at least that version resolved signature issues in that case.
    2. In another case on a later build (16.107.x), signature functionality (including adding images) was broken, and the next build (16.108) restored normal signature behavior.
    3. Older release notes also document signature-related bugs (for example, images not displaying in sent mail) that were fixed in later updates.

    Given that spacing/layout in signatures changed after updating to 16.109.26051019, this is likely another build-specific regression. The practical steps are:

    1. Check for and install the latest Outlook for Mac update (a newer build may already include a fix, as happened with builds 16.64 and 16.108).
    2. If the issue persists on the latest build, monitor the “Fixes or workarounds for recent issues in Outlook for Mac” page and the Outlook for Mac release notes, as signature issues are tracked and updated there.

    If updating resolves the problem, no further configuration change is typically required; signatures should regain their previous formatting behavior once the bug is fixed in a newer build.

    Hi Rolando

    Because you are using a business account, your signature may be tied to a feature called "Roaming Signatures," which syncs your signature to the cloud. Whenever there is a new update to the Outlook client, the way the app reads hidden HTML formatting (like line breaks and paragraph spacing) can sometimes change, causing the text to collapse.

    Here are some recommendations from my side and I hope it will be useful

    Fix the spacing using Outlook on the Web: Since your signatures sync via the cloud, resetting the format on the web version is usually the most effective fix.

    • Log into Outlook on the Web (OWA) using your business credentials.
    • Click the Gear Icon (Settings) > Account > Signatures
    • Check your signature here. If the spacing is missing, correct it in this window.
    • Save your changes, restart your Outlook for Mac app, and allow a few minutes for the corrected signature to sync back down.

    Use "Soft Returns" for line breaks

    If you are fixing this directly inside the Outlook for Mac app, standard paragraph breaks (pressing Return) might be rendering incorrectly in this new update.

    • Go to Outlook > Settings > Signatures and edit your signature >Delete the collapsed spaces between the lines.
    • Instead of hitting Return, hold down Shift + Return on your keyboard. This creates a forced line break rather than a new paragraph. Save and test a new email

    Strip hidden formatting

    If the signature was originally copied from a Word document or a website, it might contain hidden code that build 16.109 is struggling to read. Try copying your signature text, pasting it into a plain text editor (like TextEdit on your Mac) to strip the code, and then pasting it fresh into the Outlook signature box.

    Additionally, because version 16.109.26051019 is a very recent release, this may be a newly introduced issue. If the steps above do not permanently resolve the problem, I highly recommend feedback this directly from the app, so the Mac engineering team receives your diagnostic logs. You can do this by opening Outlook and navigating to Help > Contact Support (or Help > Feedback > Report a Problem).
