large message 1Mb + no body

[five0.4tluv]

I've got some email from our parent company that are large 1Mb+. In the web client the message list shows parts of the subject and body as any other normal message, but when I click on the large messages the subject shows but no body text at all. There is no change if I turn on the reading pane of switch to view text mode. And the same message in another users mail yields different results, some show the body and some don't. I'm not sure where else to look.

I went back a few days and it appears to be very random. I've got email prior to Aug 3 that can open and some that can't and none from Aug 4 after 1am and beyond

The same message went to a user that using Exchange with Outlook. He can view the message without any issue.

If I open the web client using Standard HTML it displays all of these message bodies. It appears that this is related to AJAX rendering...
