My companies Exchange server 2010 is currently being hosted outside our network by a third party provider.
I have been administrating it for a few years now and we are now looking to possibly have our own Exchange server "in-house" (inside our network)
My plan: I am thinking of setting up a test server on a low end server with a trial of Exchange 2013. I want to get the feel for the setup process and do some testing with my technical team and to save on cost until I am ready to go live with our production server. After we are satisfied with the test server we will purchase a higher end server spec'd out for production use for 250 mailboxes.
I have some questions about the in-house setup.
1. Do we have to use a different domain name for our testing (test email accounts) since our live server at the third party company will still be active.
2. Can anyone recommend a trial spam filter I can use as part of my testing.
3. Can anyone recommend an Exchange support company that can help with "out of scope" questions and issues that come up. Paid support is ok.
4. Once we go live with our production server can we migrate our mailboxes over without our third party hosting company knowing about this.
5. Any common issues that I should avoid running our Exchange server in-house in a Windows environment and/or while having our live server active at the third party company.
6. Let me know if "my plan" mentioned above is the right approach.
Thank you much!
