I finally installed Exchange 2010 on my network.
However, I don’t fully trust my setup so I did not move my company’s emails to it. I’ve set up OtherDomain.com as the domain for Exchange.
MyCompany.com’s emails are hosted with an external ISP.
1. How do I move now MyCompany.com’s emails to Exchange?
Is this as simple as?
• Adding MyCompany.com as Accepted Domain to Exchange’s Organization Configuration | Hub Transport
• Pointing MyCompany.com’s MX record to Exchange
2. If I want to go back to my ISP, I just have to re-point my MyCompany.com’s MX record to the ISP’s email server?
More, than that, can I switch back and forth between hosting my emails on my Exchange or hosting them by my ISP, with having only the ‘penalty’ of propagating the MX record’s IP (10-20hour delay, that I can afford in the weekends)?
