Disable Outlook message of “opening a lot of items could take some time”

Hi there,

I constantly have to open a lot of mails at a time, sometimes 20 or more at once.

Is there any way to disable the Outlook 2003 message that bugs you about opening a lot of items could take some time?

I have scoured the web and Google, but still no luck!

Please help as this is really starting to irritate me a lot!

Thanks guys…
