One of the many things I do for a living is do all the IT-related things for my office. We have had off and on email blocking issues (we get added to spam lists) for 2 years now and so I'm going to switch providers. The problem is right now is that we have shared hosting so we get punished for some other doofus sending out emails about fake Rolexes.

I'm going to switch to Exchange Online and I'm wondering if things actually are as simple as I think they are. By my understanding, all I have to do is change the MX record for our current webhost to point to the Exchange server.

To be clearer, our existing host hosts our website and email. All I want to do is make our email addressed to "[email protected]" to go to the appropriate Exchange server, which is obviously somewhere else. So again, by my understanding, I should change the MX record *only*. If I touch other DNS settings, it'll likely kill the website, which we want to keep.
