i would love to be able to use more characters to complete my personalized signature from my email.

well I spent hours trying to locate someone who seems to understand that I use this email for my career/job stuff and would like to have more options for fonts and signatures. I am unable to completely input my business info. because "sally lil outlook cant hold that many characters and four lines of business information that could stay there permanently on any other email systems, instead I find myself typing my preset signature  everyday!!! please someone tell me how to fix this annoying problem not to mention time consuming.. thank you!!
