Good Day; Through acquisition, our company has grown from 1 site to 3. I have been tasked with evaluation different strategies for unifying e-mail for them. I have not worked with Exchange in a very long time, and have forgotten much of what I knew back in the day. So I'm just looking for some guidance about deployment options. For now, I'm not concerned about licensing; I'm just studying the technical feasibility. Current landscape is: MainSite has AD Domain= MainSite.local, External (e-mail) domain = MainSite.com, + 5 alias domains Site 2 has AD Domain = Site1.local, external domain = Site2.com + 3 alias domains Site 3 has AD Domain = Site2.local, external domain = Site3.com + 2 alias domains There are no inter-domain trusts, and each AD domain is its own forest. MainSite and Site2 are both using non-Exchange mail servers, with Outlook (2007 or better) as the client. Site3 is using Exchange 2010, also using at least Outlook 2007 Defined goals are (1) all mail on one server, (2) all e-mail addresses end with MainSite.com To bring the other sites into the Exchange on SiteB, do we need to rename the other two AD domains, so that all are the same? Is creating a new forest containing the three existing AD structures a feasible plan? Can Exchange provide e-mail to accounts not on the Exchange server's domain? Are there limitations? Do I have to rename the Exchange AD Domain in order for mail addresses to always have the desired '@MainSite.com' format? From What I've found in web searches, renaming an Exchange domain can be an adventure. I really want to engage a local consultant for a few hours to get fine details on this, but my boss wants to first 'see what I can find out on my own'. Mostly, I want to get a little better handle on how complex a project this is. Merging everything to one of the non-Exchange servers is fairly straight forward: add the domain aliases, export the user's PST file, reconfigure the server connections, re-import the PST. If anyone has advice or good links to read, I would be most appreciative.
