What do Exchange Virtual Directories Do?

This is just a quick little reference post to answer a question that isn’t well covered. Most Exchange admins are familiar with how to set the Virtual Directories in Exchange after a new server is added or a after initial deployment. What’s less clear to most is what those VDirs actually do as far as Exchange’s capabilities are concerned.…

If You Have a Cisco Firewall, Disable this Feature NOW!!!

I don’t often have an opportunity to post a rant in an IT blog (And even less opportunity to create a click-bait headline), but here goes nothing! Cisco’s method of doing ESMTP packet inspection is INCREDIBLY STUPID and you should disable it immediately. Why do I say that? Because when Cisco ASAs/whatever they call them these days are configured to perform packet inspection on ESMTP traffic, the preferred option of doing so is to block the STARTTLS verb entirely.*…

Do I need Anonymous Relay?

Problems

If you have managed an Exchange server in the past, you’ve probably been required to set things up to allow printers, applications, and other devices the ability to send email through the Exchange server. Most often, the solution to this request is to configure an Anonymous Open Relay connector. The first article I ever wrote on this blog was on that very subject: http://wp.me/pUCB5-b…

How Does Autodiscover Work?

Autodiscover is one of the more annoying features of Exchange since Microsoft reworked the way their Email solution worked in Exchange 2007. All versions since have implemented it and Microsoft may eventually require its use in versions following Exchange 2016. So how does Autodiscover work?

Some Background

Prior to Exchange 2007, Outlook clients had to be configured manually.…

Exchange Autodiscover – The Active Directory SCP

In a previous post I explained how you can use a SRV record to resolve certificate issues with Autodiscover when your Internal domain isn’t the same as your Email domain. This time, I’m going to explain how to fix things by making changes to Exchange and Active Directory that will allow things to function normally without having to use a SRV record or any DNS records at all, for that matter.…

Exchange Transaction Logs – Reducing the Confusion

Exchange Transaction Logs are a commonly misunderstand facet of Exchange Server. There’s a lot of misinformation out there as well as a lot of confusing documentation. In this post, I’ll be going over the basics of Transaction Logs and explaining what they are, how they work, and, more importantly, what they are for.

Public Folder Migration Issues Resolution for KB 977921 With PFDAVAdmin

The Issue

When you migrate from Exchange 2003 to Exchange 2007+ you can run into a number of problems that are due entirely to the differences in how Exchange handled public folders. One of these problems, as explained in KB 977921, is particularly annoying. The problem shows up after the public folders are replicated to an Exchange 2007/2010 server (Exchange 2013 uses a completely new system for Public Folders, and migration to it is completely different so the issue doesn’t really appear for that version of exchange).…

Removing Addresses from an Exchange Server with Powershell

This is probably a rare issue, but something I’ve come across in my work. Occasionally an Exchange Administrator may need to remove an Email address domain (The part of the email address that comes after the @ sign). For instance, you may be in a situation where a portion of the users in an Exchange environment are migrated to a Cloud based email solution.…
