Exchange Server 2003 Security Review

The question was recently posed on a mailing list asking whether there was any book that covered the Exchange 2003 security model in depth. The question came up for the poster because of a recent video that is making the rounds on youtube and elsewhere...

Outlook and Exchange on the same computer

In 2004, I wrote an article Why Can't I Have Outlook and Exchange on the same Computer? It applied to versions of Exchange prior to Exchange Server 2007. When written, E12 (Exchange 2007) was still quite early in development at MSFT... Today, times...

Export Mailboxes Larger than 2 GB to ANSI PSTs

I don't often just link to another blog posting for MY blog posting, but this one deserves it. It's not new, but last year fellow Exchange MVP Glen Scales wrote a script which allows you to export large mailboxes to ANSI PSTs. It does this by...

"Microsoft Exchange Service Host" fails to start in Secure Exchange 2007 Environments

On Exchange Server 2007, especially post service pack 1 (I ran into this problem while installing service pack 1 update rollup 2), it appears that some of the assemblies (that is, parts of the various Exchange programs) are "signed with Authenticode"...

Creating Many Users with PowerShell and Admod

One of the mailing lists I read and occaisionally post on is named ActiveDir. A lot of heavy-hitters in the AD world hang-out around there. I've learned quite a bit by lurking there. A recent poster had wanted to create a few thousand accounts for...

I Had To Laugh...

We consultants help each other out, of course. I know Exchange and Active Directory pretty well, but put me in front of Citrix or a big T/S farm or a PKI implementation - heck, I'll scream for help without any qualms whatsoever. So, a consultant I...

Chapter 12 - Exchange 2003 Scripting

Over three years ago, a particular publisher in the computer field contracted me to write a book - which I did. They paid me for it, but they chose to never publish it. It was written with Exchange Server 2003 service pack 1 in mind - as you read the...

A Rookie Mistake - Moving Mailboxes

I am embarassed. I spent over an hour today trying to figure out what I had done wrong and what the problem was. In the process of migrating a client's mailboxes from Exchange 2003 to Exchange 2007, the move-mailbox wizard was giving me an error I...

Outlook Profile Redirection

I imagine that many of my readers are already aware of this fact, but it is a very common question on the forums, especially as the pace of Exchange Server 2003 to Exchange Server 2007 upgrades appears to be increasing. The question is this: when I move...

Clustering on Exchange Server

Clustering is a Windows Server technology that allows for a "stand-by" server (call it "Server 2") to take over the load and activity of another server (call it "Server 1"), if that server should fail (i.e., if Server 1 should...

Exchange Server 2007 service pack 1 rollup 2

Exchange 2007 SP1 RU2 is out! This one is pretty big for clusters and if you use POP3 and IMAP in your organization. I recommend you roll it out quickly. More about it at KB 948016 . Lots of patches in this one.

Other Certificate Limitations with Exchange/OCS/WM

This is turning out to be SSL certificate week here at TheEssentialExchange.... not planned that way, just the interesting items that are crossing my computer. Yesterday, I wrote ISA 2006 and SAN/UC Certificates describing how ISA 2006 requires careful...

ISA 2006 and SAN/UC Certificates

Much has been written about ISA 2006 "not supporting SAN certificates". And, to some degree, this is true: the RTM version of ISA 2006 will only recognize the first subject alternative name in a certificate. So what do you do if the name you...

Inexpensive UCC/SAN Certificates

When Exchange Server 2007 was first released (even before then, if truth be told), there was quite an outrage that in order to use a simplified configuration process for Outlook Anywhere, OWA, and AutoDiscovery, the Exchange administrator had to use a...
