The company I work for hosts our email in their office in California. The office I work for is on the East Coast right outside NYC. We have 298 users on handled by the server. The users are in 4 offices, 2 in Ca, 1 in DC and 1 her on the East Coast. We have about 100 of the 296 user. My Boss asked me today if we could host our own Email server separate from them. We all have the same domain name, so @companyname.com is shared by all. Is it possible for us to host the email for only our users, and allow them to handle their own users. I could not definitively answer the question, but my boss, the Vice President of this company wants an answer. If so we will buy the server and take over hosting email for just over 100 users.
Please advise if this is possible.
