At home I am running Win2k Advanced Server and Exchange 2k. I also have a DSL connection. After about a year and a half...my IP address finally changed. Within a few minutes I had my webs backup and running and I thought all was well. When I got to work today I found that I could not connect to to my Exchange server at home via Outlook Express. I have an IMAP account set up so I can check my mail while I'm at work. I have checked everything I can think of on Exchange.....what am I overlooking??? Thanks.
