Add HTML signature to Outlook 2007
In order to get an existing html signature file added to Outlook 2007 there are several steps to take that are very different from previous versions of Outlook.1) In Outlook 2007 open Tools > Options > Mail Format and select signatures
2) Create a new signature and give it a meaningful name. Press Ok.
3) Open up an explorer window (win + e) and navigate to C:\Documents and Settings\User name\Application Data\Microsoft\Signatures. If you can not see the Application Data folder you need to show hidden files and folders.
4) Open the html signature file that you just created with notepad,
right click > open with.
Remove the contents of this file and replace it with your html signature code.
Save this file, file > save.
5) While you are in here it wouldn't hurt to make the text version of the signature look like you want it to as well.
Once you have edited the html source of the new signature you should see it in its correct form in the signature area of Outlook 2007
