1. Configure Outlook to Compose Messages in HTML Format

Are you using images in your Outlook signature? If so, you need to ensure that Outlook is set to compose messages in HTML, rather than Plain Text. Here are the steps for the same.

Step 1: Open the Outlook app on your PC and click the File menu at the top-left corner.

3. Open Outlook in Safe Mode

Another reason why your Outlook signature may not work properly is due to conflicting third-party add-ins. To check for this possibility, you can try opening Outlook in safe mode. For that, hold down the CTRL key and double-click the Outlook shortcut. Select Yes when the confirmation prompt appears.

Open Outlook in Safe Mode

After Outlook opens in safe mode, check if your signature is working properly. If it is, one of the third-party add-ins may be to blame for the problem. To identify the one causing the issue, you need to disable all Outlook add-ins and then re-enable them one at a time.

Step 1: In the Outlook app, click the File menu at the top.

Step 2: Use the left pane to open Options.

Enable all your add-ins one at a time until the issue occurs again. After you find the problematic add-in, consider removing it to resolve the issue for good.

4. Update the Outlook App

If you have disabled automatic updates for Office apps, you may be using an outdated version of Outlook. This can lead to all kinds of issues, including the one discussed here. Here’s how you can check if a newer version of Outlook is available.

Step 1: Open the Outlook app on your PC.

Step 2: Click the File menu at the top-left corner.

Step 3: Switch to the Office Account tab. Click Update Options and select Update Now.

Update Outlook

Wait for Outlook to install pending updates and then restart the app. After this, Outlook should display the email signature as before.

5. Remove Office Setup Registry Keys

If your email signature is still not showing up in Outlook, there might be an issue with the Office setup registry files. To fix this, you will need to remove the problematic registry entries associated with the Office client using the Registry Editor.

Since registry files carry important configurations for Windows, it’s a good idea to back up all the registry files or create a restore point before proceeding.

Step 1: Press the Windows key + R to open the Run dialog box. Type regedit in the box and press Enter.

Open Registry Editor

Step 2: Select Yes when the User Account Control (UAC) prompt appears.

Step 5: Select Yes to confirm.

Restart your PC after this and then check if the issue is still there.

Step 1: Right-click on the Start icon and select Installed apps from the list.
