Preventing AutoCorrect Capitalization of first word of line

[Sandy M]

I am trying to turn off the AutoCorrect option that capitalizes the first
word of
each new line.

Word is the email editor.

I went into the AutoCorrect options in word and de-selected the option
to Capitalize first letter of sentence.

I did the same in Outlook.

I guess this is not how you turn off this type of capitalization because the
first word of each line is still being capitalized.

Can someone tell me how to prevent this?

Thanks
