Width issue in Outlook 2010

[wesderta]

I have a fair bit of experience coding emails and am familiar with the nightmare that is Outlook but this is a new one for me and, what's more, it only seems to be affecting some users. Basically, in our newsletter templates there is a table designed to nest the content in. It has columns on the left and right with width attributes to act as margins. For some users of 2010, Outlook seems to collapse the columns, for others it doesn't.Is anyone aware of a setting in Outlook that might cause this to happen?Here's a version of the code, with the contents stripped out:\[code\]<table style="FONT-FAMILY: Helvetica Neue, Arial, sans-serif; COLOR: #4b4b4b; FONT-SIZE: 12px" border="0" cellspacing="0" cellpadding="0" width="600" bgcolor="#FFFFFF" align="center"><tbody><tr><td rowspan="6" width="30"></td><td height="30"></td><td rowspan="6" width="30"></td></tr><tr><td style="PADDING-BOTTOM: 40px"><table style="WIDTH: 540px"><tbody><tr><td style="TEXT-ALIGN: right; PADDING-BOTTOM: 10px; FONT-SIZE: 10px"></td></tr></tbody></table><table style="WIDTH: 540px" border="0" cellspacing="0"><tbody><tr><td width="340"></td></tr></tbody></table></td></tr><tr><td style="PADDING-BOTTOM: 20px"></td></tr><tr><td style="PADDING-BOTTOM: 45px; FONT-SIZE: 10px; BORDER-TOP: #412878 4px solid; PADDING-TOP: 20px"></td></tr></tbody></table>\[/code\]Thanks,M
