IE/Access error

[cuthbert james]

Working in a Server environment, one of my users receives a error when he
tries to open a mailto link on a webpage. He receives the message -

"Could not perform this operation because the default mail client is not
properly installed"

I've gone to tools -> options and set Access to his default mail but that
did not work.

I've also looked around on forums and gone into the registry and tried
several new strings as suggested but that has not worked either.

Has anyone got any suggestions as how to fix this problem?#

Thanks in advance
