You've posted your question in the wrong forum. This one is for Exchange deployment, i.e., installation, issues. You might want to check your browser's settings. Try another browser like Firefox or Google Chrome and see if the same thing happens, which might help you rule out Exchange as being the culprit.Ed Crowley MVP "There are seldom good technological solutions to behavioral problems."
