Formatting of ordered lists in Outlook 2011

I have a long standing irritation with Outlook 2001. If I am writing an emailiand try to manually create an ordered list like this

a) First point

b) Second point

c) Third point

Outlook converts my manual list into an automatically ordered list that looks like this

A) First point

B) Second point

C) Third point

Maybe I'm being fussy, but I would rather not have Outlook automatically format my list, and convert my lower case a), b), c) into upper case A), B), C).

Is there any way of either stopping Outlook from automatically formatting my list, or of controlling the formatting it decides to apply so it does not convert my lower case a) to upper case?
