Exchange 2010 is Code Complete and on its way to General Availability
Published Oct 08 2009 12:00 PM 13.7K Views

We are happy to announce that Exchange 2010 is Code Complete!  Our senior leadership team has signed off on the final code, and it has been sent to our early adopters for one final look before its public release. This Release to Manufacturing (RTM) milestone means we are on our way to general availability and the launch at Tech·Ed Europe 2009 (http://www.microsoft.com/europe/teched/) in early November.

For those of you attending Tech·Ed in Berlin this year, be sure to check out the Unified Communications track, which is packed with technical content on Exchange 2010. And be sure to visit us at the Exchange product booth in the Exhibition Hall and let us know what you think of the product. Crystal Flores, who interviewed some of you on video at Tech·Ed North America earlier this year, will be on-hand in Berlin in a few weeks, armed with a camera and interview questions.  A group of us are also marching to Las Vegas for Exchange Connections the same week where our fearless leader Rajesh is giving the keynote.

We hope to see you in Berlin or Vegas, but if you can't join us in person, tune in via the Web (www.thenewefficiency.com) to be part of the launch.

Alot of chest beating here, especially by internal MS staff, lets see how well it goes when put to the test in the real world. Sounds good but like so many MS offerrings they sound good but fail to deliver in production. I hope it lives up to the hype cause it will make my life easier.

Yeah. Let's hear about some large reference sites.

Thanks everyone for your kind comments and congratulations!

"Yeah. Let's hear about some large reference sites."

Awesome looking forward to the rtm bits.
Not applicable
Congratulations!

Very excited to transition my own Exchange environment and those of our customers!

Question: I know an inplace upgrade from RC1 to RTM will be supported (or was intended to be), but will Mailbox move requests work from 2010RC1 to RTM? Just to be safe, I prefer not do to an inplace upgrade.
Not applicable
Well Done !

But not too fast guys... when will antivirus products be available for that new version... talking about ex2k7, i rembember we had to wait a long time before a reliable AV product.
Not applicable
Good work.  Well done to all.
Not applicable
Do you know when it will hit MSDN? Also will the RTM build number be the same as the final release? Meaning is it "safe" to put 2010 RTM into a small IT production environment?
Not applicable
Can you list the differences between Standard and Enterprise?
Not applicable
I saw a lot of questions here last night that made me post another ex2010 entry on my blog on planning

Not applicable
Great job. Keep up the good work.
Not applicable
Will the code complete version have better compatibility with 2007 SP2? I have a 2010 RC1 and a 2007 SP2 server. And my Hub Transport or Client Access are not visible from the other server (ie if you're in the 2007 EMC I can't see the 2010 CAS and Hub Transport or vice-versa).

Hi,

what about scalability? Can someone point me to a case study about large deployments of exchange ~ 100.000 mailboxes?
Not applicable
Great Job and a honour be a part of the program ;)

Quoting @IvanStone

or is the ten million on live@edu not big enough?
Not applicable
Wow! Congratulations! can't wait!

@Exchange Scalability 100 mailboxes isn't that hard for exchange to manage. A truley large scale exchange environment would be at least 750 - 1000 mailboxes minimum. I have a friend who is going to run 250 mailboxes on one exchange 2010 box. You just need to have a good Drive array, decent amount of RAM(for 100 Mailboxes i would recommend at least 3gb on server 2008 or 2008 R2 but I would go with 5gb or 6gb if you can) and a dual core system.
Not applicable
Hi Scott,

well, I thought more of 100000 mailboxes. :) I thought that it's common to write 100000 as 100.000 for better readability. We are currently having about 70.000 students at our university and at the moment we are using Communigate Pro which scales very well - even on low end hardware. But maybe we are moving to Exchange 2010 in the future. We just don't yet if we should go the Exchange way or stay with Communigate  Pro.

@Scott Pauls
I think that "Exchange Scalability" is European and using the decimal to separate thousands instead of a comma (eg 300.000 is 300,000). :)
