Exchange 2010 Free space within a Mailbox Database

In previous versions of Exchange Server there was a process called "online maintenance". This process ran at night and one of the tasks was to an online defragmentation to do within the database. The task was that the empty spaces are grouped together resulting in more efficient use of the Mailbox Database.

In Exchange 2010 has changed and there is a 24×7 online process. There is also the option of online, direct to see how much space is available within the databases with the Powershell command:

Get-MailboxDatabase –Status | fl Name,AvailableNewMailboxSpace

Output:

If we were to do an offline defragmentation on the Mailbox Database the mailbox database would be approximately a 90MB smaller.

This is on my test Exchange 2010 server with only a few mailboxes. In normal production enjoinment this will  be a lot more.

In Exchange 2010 you can you a online mailbox move. There fore you can
better create a new mailbox database en move all the mailboxes to the new mailbox database.
Then you have the same result with no down time.

Publishing Outlook Anywhere Using NTLM Authentication With Forefront TMG or Forefront UAG

This white paper provides detailed information about publishing Microsoft Exchange Server 2010 using Forefront TMG or Forefront UAG to secure access for Outlook Anywhere when using NTLM Authentication.

When you publish Exchange, Microsoft offers two software-based options: Microsoft Forefront Threat Management Gateway 2010 and Microsoft Forefront Unified Access Gateway 2010. Both options offer publishing wizards and security features to provide secure access to Exchange when it’s accessed from outside the safety of the corporate network.

This white paper provides detailed information about publishing Microsoft Exchange Server 2010 using Forefront TMG or Forefront UAG, including how to choose between them for different scenarios, and provides specific steps you can take to configure Forefront TMG and Forefront UAG to publish Exchange 2010 while using NTLM authentication for Outlook Anywhere access.

Microsoft Certified Master Exchange Video Preview

There is one Microsoft exam that I find very interesting. That is the Microsoft Certified Master for Exchange program.

I found a nice video what tells what we actually do in the classroom during Microsoft Certified Master rotations?  Well, here is a 30 minute summary of the Exchange 2010 header firewall from  Brian Reid, one of our regular MCM instructors.  Brian covers the header firewall and much more during his two and a half day delivery of instruction and labs on Exchange Transport.

You can find the video HERE

Publish Exchange 2010 With TMG (Forefront Threat Management Gateway)

When you want you use Forefront Threat Management Gateway to publish Exchange 2010 you must do the following things

I my case I have the following URL’s registered with the certificate.
webmail.wardvissers.nl
autodiscover.wardvissers.nl
