Adding a CallMe! button to your Outlook signature is similar to the other email programs. The key is to create a small file using a text editor like Notepad containing the HTML signature.

1. Go to the CallMe Button Wizard at Support > Click-to-Call and enter your Account-ID and extension.
2. Decide how you want your button to look and then copy the HTML from the box in Step-4 into a plain text file using an editor such as Notepad.
3. Add any other personal information you want to the file, and save it with the name “signature.html”.
4. In Outlook, go to Tools > Options > Mail Format > Signatures.
5. Pressing the Signatures button will show you your current signatures (if any). Press [New…].
6. Pick the option “Use this file as a template:”, and then open your saved “signature.html” file.
7. Click [Next >] and make any additions needed to the file.
8. Click [Finish], and when you return to the Options window, select the new signature in the “Signature for new messages:” and “Signature for replies and forwards:” options.
9. Click [OK] to finish!

That should take care of using the CallMe! button in Outlook. Take a look at screenshots.
