Can someone explain why Exchange can not be installed on Windows 2008 server R2 web edition? I'm new to Exchange, and I'm trying to migrate to Exchange from another mail package.If I have a DC, Active Directory, DNS, etc on another server, why can't I have another server as 2008 R2 web edition with Exchange and handle webmail?does Exchange 2007 work with Windows Server 2008 R2 web server?Thanx.

Web edition is more limited than standard or enterprise. Basically that's not what MS will support so you should follow their recommendation. It isn't supported on Exchange 2007 either. http://technet.microsoft.com/en-us/library/ee338574%28EXCHG.80%29.aspx Mark Morowczynski|MCT| MCSE 2003:Messaging, Security|MCITP:ES, SA,EA|MCTS:Windows Mobile Admin|Security+|http://almostdailytech.com

I see that they do not list it on their required OS's, but that doesn't always translate 100% into non-supported. What roles, etc does Exchange need outside of what 2008 R2 Web server provides, that's the real question. Why can't it run on it? Is there someone out there that understands what 2008 needs to have for Exchange? Thanx.Your link is a great example of what I said above, it states Windows 2008 server and Windows 2008 server R2, not what edition of Windows 2008 server (for either R2 and Sp2). From that, Exchange 2007 should run on Windows server 2008 SP2 web server.Also, I just noticed that Windows server 2008 R2 doesn't support Exchange 2007 period, so 2010 is the only option.

Here is a breakdown of different technical specs between the OS. http://www.microsoft.com/windowsserver2008/en/us/r2-compare-specs.aspx Here is what Specific OS version is listed for 2010. Web Edition is not on there. http://technet.microsoft.com/en-us/library/aa996719.aspx I have no idea why you want to use Web Edition so badly. You cant do TS and stuff like that with it. It's a striped down version for hosting web sites, that's why it's called Web edition not Exchange Server edition. I'd actually be surprised if Exchange would even install on that version.Mark Morowczynski|MCT| MCSE 2003:Messaging, Security|MCITP:ES, SA,EA|MCTS:Windows Mobile Admin|Security+|http://almostdailytech.com

Markmorow, I was able during a previous search to find the links that you provided above.I was just asking what server roles (not roles of a server), etc for that you need Windows 2008 R2. I just didn't see what web server lacked (google 2008 server roles, etc that Exchange needs on 2008 R2). As for stripped down, that's the entire reason that makes 2008 server great, you run the roles you needs. Exchange server is not a Windows 2008 server edition, nor a role to activate on standard, etc(what are you refering to above). So when I say server roles, I really mean OS server roles that can be initiated (through OS not by installing software, i.e. not what the role of the server is).So web server of 2008 R2 is in theory perfect. It has the web server and DNSroles for webmail, and outside of that it has the 2008 core to run the software - Exchange. Exchange isn't suppose to be the DC, etc.So why use Standard or Enterprise if you're not going to use all the server roles those offer.That was my question.

There are basic components that are installed on Server/Ent that aren't installed. Simply put, Exchange can't be installed on the Web edition. You are free to try and see what error message you get. I don't think other than just Web sites can be installed on the Web edition.

Hi,For the reason why we do not support Windows server 2008 R2,you can refer to the following article.Please note that it has been obsolete. Since Microsoft heard from many customers that this was important for streamlining their operations and reducing administrative challenges, so we have changed course and will add R2 support. We are still working through the specifics and will let you know once we have more to share on the timing of this update.
