If you have a custom HTML email signature from Click Creative, or if you have created your own HTML email signature, here is how to install it in Microsoft Outlook 2010/2013/2016.
Step 1: Add a New Placeholder Signature
In Outlook, go to File > Options > Mail and click on “Signatures“. Select “New” to create a new placeholder signature. Give the new signature a name you can remember.
Set to use your new Signature for both New Messages and Replies/Forwards.
Click "OK" to save and "OK" again to close the Outlook Options window.
Close Outlook
Step 2: Open Outlook’s Signature Folder on Your Computer
Here are the locations on the hard drive where Outlook places signature files, these locations are usually hidden so make sure you show hidden files and folders:
C:\Users\username\AppData\Roaming\Microsoft\Signatures
Step 3: Find and Open the New Signature file
Within the Signature Folder, locate the file that you have created in Step 1. If you see multiple files with the same name, the file you want to open is the HTM file with the .htm extension. Open it with Notepad. You can right-click on the file and select Open with > Notepad.
Step 4: Replace Placeholder Text With Your HTML Code
If your signature has been created by Click Creative, you will have received a .htm file containing the HTML code for your signature. Open this file in Notepad to view the code.
Erase all content in the placeholder signature file, and paste your HTML signature code. Hit File > Save.
Send yourself an email to test the signature.
