I am receiving and sending emails with Large Fonts randomly. I have Outlook 2007 and I've checked Zoom, formatting is set to Rich Text and Stationary and Font is set to normal defaults. This just started. Some of my other coworkers are experiencing the same thing. It is not a sender issue because it happens when I receive mail from random recipients and also when I send mail. I've contacted the senders and they all say that when they preview their sent mail, it looks fine. And, when I author emails they look fine until sent. Any ideas will be helpful. The office uses Exchange 2007 and AdvisorMail.

If you log into Outlook Web Access in your browser and look at one of the affected messages does the font look big there too?
