This is a silly problem, but have tried everything I can think of and still can't figure out how to center these two cells of text in Outlook 2003.
Here's a link to the full html file: https://github.com/justintemps/flash-updates/blob/master/dest/index-prod.html?ts=4
The offending (part that won't center) is below.
<table class="body" align="center" border="0" cellpadding="0" cellspacing="0" width="100%" style="margin: 0 auto 0 auto; text-align: center;">
<tbody>
<tr>
<td align="center" style="text-align: center;">
<center>
<table class="bodyContainer" align="center" width="600" style="margin: 0 auto; max-width: 600px; padding-top: 5px; table-layout: fixed; text-align: center; width: 100%;">
<tbody>
<tr align="center">
<td class="mainImageContainer" align="center" style="margin: 0 auto; text-align: center;">
<!-- INSERT LINK HERE -->
<a href="" target="_blank">
<!-- INSERT IMAGE URL HERE -->
<img class="mainImage" width="600" alt="" src="http://www.ilo.org/wcmsp5/groups/public/---dgreports/---dcomm/documents/image/wcms_484941.jpg" style="margin: 0 auto; max-width: 600px; padding-top: 5px; table-layout: fixed; text-align: center; width: 100%;">

</tr>
<tr align="center">

You have a few text-align:left;
's in there that are overriding the centering you're doing in parent tags.
...padding-bottom: 5px; text-align: left;">The International...
and
...line-height: 20px; text-align: left;">Lorem ipsum dolor sit...
If you remove the text-align:left;
from the examples above, these areas should center justify.
