Recently a colleague of mine migrated the mailboxes from Exchange 2003 to Exchange 2010. But he noticed something weird, in the Exchange Management Console (2010) the newly migrated users could be seen, but in the Exchange System Manager (2003) he could still see active mailboxes. He confirmed that they were still using the Exchange 2003 server. ...

Today’s question of the day is whether you can restrict users mailing to a specific Distribution Group in Exchange? Yes, you can. You can add users but also Distribution Groups to the list of who the Distribution List will accept messages from. The messages of members of the Distribution will then be accepted. A (mail enabled) Security Group is ...

Edit 6th may 2010: Similar issue with same solution is confirmed and will be patched by Microsoft. See here. Recently I transitioned an Exchange 2003 Server to Exchange 2010. For the client redirection, I mostly wait two week before decommissioning the old Exchange server. Mailboxes, mail flow, remote access and the default Public Folder are all ...

In part 1 we’ve discussed the Exchange Mode, Domain Controllers and Schema Master compatibility. In part 2 we’ve discussed the Global Catalog and the Domain and Forest Functional level up to Windows 2008. So, that leaves us with Windows Server 2008 R2. During the time it took to write this series of blogs a lot more information was made ...

In part 1 of this series, I discussed the requirements of Exchange Mode, Domain Controllers and the Schema Master in combination of various versions of Exchange. In this post I will discuss the placement of Global Catalogs (GC), the Domain Functional Level (DFL) and Forest Functional level (FFL) required. In part 3 I will discuss the ...

*** edit: updated 28/9/2009 with corrections of some errors/typo’s and added compatibility matrices In my post The Road to Exchange 2010: Migration paths I’ve discussed about the different possible migration transition paths to Exchange Server 2010. Primarily which Exchange version can be installed on which version of Windows Server and which ...

Just a few quick tips for those who want a quick result when preparing and installing for Exchange 2010 Beta. The past few days I've installed this beta too many times not to be wondering how to speed things up. So I wound up with two batch files. No unattend file (yet?) though. I already have recently updated Windows Server 2008 images. But for ...

A few days ago the beta of Exchange Server 2010 has been released. As Exchange has always been of special interest of me, I jumped at the opportunity to install it and check it out. So will 2010 be the year we will make better contact with our own mail? (for those sci-fi geeks out there, this was a reference to a A.C. Clark novel) First of I ...

So it's going to be called Exchange Server 2010! Announcement post from the Exchange Team blog is found here.Microsoft Exchange 2010 website is found here. I am currently downloading it. Hopefully I wil be able to post a first review shortly.

So at Tech-Ed 2008 EMEA IT Pro, I heard very little about the next version of my favorite groupware solution: Exchange 14. Also searching the net, didn't come up with a lot of results.
