Hi,
I have a new customer who is using Exchange. One of the client
computers (only one) is having a problem with the emails. When he
reads an email and then clicks on the next email in the list the last
one that was read disapears, deletes it's self automatically.
How can I stop this from happening?
Cheers
Lenny

Check that he doesn't have a view set - View-Arrange By-Current View
