  • To have Outlook 2010 on Windows open.

Next Step

If you are using an email signature HTML file created by our Email Signature Rescue software, click on Get Started: Windows 7/10 Installer App for a quick and easy HTML email signature install into Outlook 2010. This will complete the Advanced Installation process for you, resulting in much better image quality and attachments not showing in most email clients. You can read more about this in our Troubleshooting FAQ.

Our Advanced Installation Guide will fix issues such as blurry images and attachments showing in some email clients, however this is more technical than our Basic Installation Guide.

Install: Advanced Guide

This is our Advanced email signature installation instructions for installing a HTML email signature in Outlook 2010. These should only be used if:

  • you want images to be less blurry
  • you want images to not show as attachments in some Mac email clients

Step One

Open your email signature HTML file in Notepad or select Copy Code from your dashboard. Copy the code by pressing Ctrl + A to select all, then Ctrl + C to copy the selection. Make sure you copy all of the code. Don't use your mouse to highlight the code, only use Ctrl + A.

Step Two

Why can't the Signature Installer App find my mail account?

If your email account is an Exchange account then the Signature Installer App won't be able to recognize your mail account when attempting to install your email signature. We are currently adding functionality to the app so it will recognize Exchange accounts.

Until this is available, you can follow the Basic or Advanced Installation Guide to have your email signature installed within minutes.

When should I use the Advanced Instructions?

You should use the Advanced Instructions if you:

  • are using a HTML email signature file produced by our Email Signature Rescue software but cannot install your email signatures using our Installer App and have been advised by Support Staff to follow these instructions instead
  • are having issues with installing your email signature using our Basic Installation Guide
  • want images to be less blurry
  • want images to not show as attachments in some Mac email clients

The reason the images may be blurry using our Basic Installation Guide, is because when you paste the email signature into the settings, Outlook saves your images and compresses them, and then attaches them to the email message in it's own way. If you paste the HTML directly into Outlook's created HTML file and override the Outlook created HTML (following the Advanced Instructions or using our Installer App), it will no longer serve the blurry, compressed images that Outlook created, it will serve the images correctly, from the web server, as per your HTML file's instructions.

The images in my signature are still blurry or distorted and I'm using the Installer App or Advanced Installation Guide

If the images in your email signature are still distorted or quite blurry, it could be a display setting on your computer. Go to Control Panel > Display in your computer's settings. There you will see three text size options for 100%, 125% and 150%. If your computer is not set at 100%, it can cause the signature to look distorted when it's pasted in. Change the settings to 100% and press Apply to save them. Then re-install the email signature.

My email signature images are showing as attachments in some email software

If you are concerned about images showing as attachments when you send emails to some Apple Mac email clients, use the Installer App or Advanced Instructions to install your email signature. As explained above, this will force Outlook to use the images located directly on the web server, and not the ones it creates, compresses and attaches instead.

My email signature does not look right when I paste it into Outlook 2010

First check - has the user selected all of the HTML?

A majority of the time when this happens, the user installing the signature has not copied all of the relevant code before pasting it into Outlook 2010. To ensure that all of the code from the signature is copied, the user needs to use Ctrl A to select the signature when open in the browser or full screen preview and Ctrl C to copy it.If the user uses their mouse to select the code, they may not select all of the HTML for the signature to work correctly, which will cause the signature to look different when pasted in.

Second check - has the user deleted all prior HTML/ characters/text from the signature settings box before pasting?

You need to make sure you delete everything from the signature box before you paste the signature in. If you do not delete everything before you paste your signature in, it will not work correctly. Delete all of the email signature from the signature settings box by selecting it all (Ctrl A) then hit Delete. Make sure that your cursor is at the top left of the signature box and you cannot select anything inside the box. You should not be able to move the cursor anywhere, it should remain in the top left corner. You may not be able to see it, the only way to ensure you have deleted it all it to double click around inside the box and delete anything you find. Now copy and re-paste in your email signature, using only Ctrl A, Ctrl C and Ctrl V.

Third Check - does the User have their text size display settings set higher than 100% in the computer settings?

To find this out, go to Control Panel > Display in your computer's settings. There you will see three text size options for 100%, 125% and 150%. If your computer is not set at 100%, it can cause the signature to look distorted when it's pasted in. Change the settings to 100% and press Apply to save them. Then re-install the signature following our guide.

The email signature preview box cutting off email signature view in Outlook 2010

We have noticed that the preview box in the Outlook 2010 email signature settings may cut off your HTML email signature preview. Usually the email signature has been pasted in correctly, so do not touch it at all once you have pasted it. Double check if your email signature is installed correctly, by composing a new email message instead and sending a test email to yourself.

When I compose an email message, it's composing in plain text

If you don't see any images or colors, or your email signature has lost it's formatting when you compose a new message, it's most likely that you have your compose settings are set to plain text. Go to your compose settings and change it to HTML. See this article for more information.
