Microsoft Exchange and Domain Names

Microsoft Exchange and Domain Names

I posted this earlier today but it didn't take. Here's another go:

1. Can I set up my company's domain name on Zoho, like you can with Google Apps? There are very few references to this; one explanation I read in this forum said that it was manual -- that a Zoho technician had to set it up for the user. This seems extremely inefficient.

2. Can I use Outlook as my email client if I switch to Zoho? What about Apple Mail 3.5 or Thunderbird?

3. If I convert to Zoho, what will happen to all of my company's old emails that are currently stored on our Microsoft Exchange Server?

Thanks,

Nick Peterson
