Viewers can't read email message when reply or forward

[JoAnn]

We updated our signature for Outlook the other day and now everytime I send
someone a message that I am either replying to or forwarding they can not
read anything I wrote. The only information they see is my signature block.

I have tried removing the stationary for my emails, changed the message to
rich text format and various other tests. So far the person who I reply to
says they can now see my message when I reply, but still not when I forward.

Typcially, when I replied or fowarded a message to someone and then go to my
Sent Items folder, I can not see my message.

Help! I can't seem to resolve this issue!

Thanks.
