You can download a custom msgbox from this site
that hasn't got that limitation plus has a lot of other useful features:

Hi all, I'm trying to post a disclaimer in a financial model through a
msgbox that pops up when opening an excel file. The problem I have is
that the msgbox has a space limit of 1024 characters which I'm afraid
is not long enough. What alternatives do I have??? Thanks a lot!
