I have been experiencing an issue with Outlook 2000 and the ISA server. When a web address is included in the message body, and the user clicks on the web address either Internet Explorer opens and hangs on a blank screen or does not launch at all. This issue seems to only be resolved when Word is selected as the default mail editor within Outlook. When ISA settings are turned off the web address launched without a problem - with Word as the editor and without. Has anybody else experienced this and if you have, is there some other workaround? Thanks.
