Receiving blank mail

[Shoomz]

We upgraded Outlook 2003 to Outlook 2007 with SP1.

After the upgrade we receive blank e-mails. It is not always the case and it
is kind of random.

Some cases:
- One person sends an e-mail to several people. On of them receives the mail
blank while others receive the mail normal. Resending the mail, the person
that received the blank mail, can now read it normaly.
- When recieving a blank mail, you can read it on the blackberry. Forward
the mail to someone, you will receive a blank mail, doesn't matter who
receives it. Disabling AV doesn't change it.
- The blank mail can be received from internal as well as external sources

It appears to be random and we can not reproduce it, except from the forward
from the Blackberry.

Some related software we have.
- Office 2007 with SP1 installed
- Exchange 2003 with the latest patches running on W2k3
- Nod32 version 3.0.667
- Clients run Windows XP SP3

Anyone have similar problems and/or have any suggestions how to solve this
issue ?

Added note.

When I receive a blank mail, I can read the body (the first line) when the
popup occurs when you have outlook 2007 minimized. Opening the mail, body is
blank with no characters in it.
