We have recently added Outlook2000 to our organization. The users with Outlook2000 are unable to send or receive certain attachments in email. I found the information regarding the security levels. Apparently, our 5.5 server is set to Level 1 which blocks certain attachments. This only occurs on our Windows2000 users. A user with Outlook2000 in Windows95 doesn't have this issue. Where do I change the security level setting? Is this on the server or the client?
