What happens if Exchange loses internet?
When our internet went out for 2 days recently our Exchange server was not online. So what happens to emails sent to our server at that time?
When I first setup our server, I disconnected the server from the internet and sent a few emails from Hotmail and waited a few minutes. When I reconnected the server, the emails were instantly received. Looks like this wasn't the case because no one received any emails during the recent internet downtime.
So what happens if Exchange loses internet? Do the emails wait on Gmail (or Hotmail, etc) servers? Do they bounce back to the sender?
If they are truly 'lost', what should I do for backup? I read about Google Postini...
