Exchange and backup dial up

Before I answer your question, I just can't resist saying this:

If the internet goes down, we all have some bigger issues to worry about.

So, how do you specify exchange to use a dial-up connection if your connection to the net fails.

Well part of the problem is that Exch does not automatically fail over to a dial-up. It will attempt to use any connection that is available.

In order to get it to use a dial-up, you have to specify it in the Dial-up Connections in the IMS. But it will then use that connection instead of your permament connection.

Exch was created with the notion that it would always have a permament way out to the net.

I take it what you are really asking is what happens if YOUR route to the Internet fails. This issue should be handled by your router switching to backup routes ie ISDN failover to analogue, DSL\leased failover to ISDN etc, For Exchange you would have to manually switch to a backup Dial-Up route to an ISP that would allow Mail Relaying from your domain name.

Hope this helps
