Email Signature HTML Issue

Question

Hello, 
I need some help. A few months ago I created an email signature with HTML for a client. Pretty standard code.
I created a test signature within outlook.
I located the signature files on my computer through: User/AppData/Roaming/Microsoft/Signatures
I could see the three signature file formats (HTML Document, Rich Text Format and Text Document). When I opened the text file, there was a bunch of code. I would navigate to the specific section and insert my custom HTML code (the code that I wrote).
Everything worked perfectly. 
However, now when I navigate to the same signature file.. and open them.. the naturally generated code for the signature file is not appearing. If I open the HTML document, and view the page source then I am able to see it. 
Any ideas why it's not appearing within the Text Document? 
Thank you!

Hello,
By "Text Document", do you mean the Plain Text signature (.txt file)?
As the name suggests, Plain Text does not support any type of formatting. For example, if you include an image in your signature, as shown below, the plain text version will be blank. So if you enter any HTML code into the Plain Text signature, it will not
work.
If you want to modify the Plain Text signature, please refer to the following KB article and look at the "Modifying the Plain Text signature" section:

Hope this helps.
