Formatting text ONLY above the signature. Help!!!

Question

I’ve been having Vba macro trouble where I’ve tried countless ways to format my emails. For example I have my email format specific regular expressions such as “[0-9]{1,2}:[0-9]{1,2}” for time and “[0-9]{1,2}/[0-9]{1,2}/[0-9]{2,4}” for any date format in ##-##-## or ##-##-##.

In short I created a macro that can format it the way I want. However I’m having a hard time making it only apply to the new text I add in a reply or forward email. Currently it will apply the formatting to the existing email thread below.

Does anyone know the parts of the code that will help with this? Also I would want it to work on both while inside of a outlook email preview and it’s own separate pop out window.
