A customer contacted to report a problem with Outlook's AutoDiscover feature. The customer was a former BPOS customer that was testing some mailboxes deployed onto a new on-premises environment. The testExchangeConnectivity validation tool was reporting...

Secure by default is a great response to the security problems that plagued Microsoft nearly a decade ago, but sometimes we, as consumers of a product, confuse the concepts of vulnerability and functionality. The receive connector is an example that I...

Ran into this event on an Exchange DAG where the customer was reporting that Exchange seemed to be making arbitrary decisions to randomly failover from Node1 to Node2 of the mailbox cluster. Some investigation showed that the 1006 event always corresponded...

It's always the hardware. If it's not the firewall, it's the network. If it's not the network, it turns out, it might be the CD drive. Strangest situation encountered today. Tyring to install Exchange 2010 SP1 integrated on a new server (virtualized)...

I recently was working with a customer to build a reporting solution for their Exchange 2010 environment. The report was going to be used for billing and compliance administration. Basically, the organization needed to know how many mailboxes per customer...

In the RBAC world, it should be possible to create a new management role, based on the built-in role "Mail-enable public folders." The built-in role allows delegates/members to run the enable-mailpublicfolder cmdlet. When you add users to the built-in...

I've been working an interesting challenge this week in attempt to convert email address policies from Exchange 2003 to Exchange 2010. As part of the conversion process, LDAP queries that define the recipient filter (to which the policy will apply) need...

UPDATE (3/28/11): I've been thinking about this post for awhile, unable to believe that someone else hadn't already thought of the obvious. Did a little research this morning and realized all my work was in vein (but I am happy about it). Excel does have...

I am sure this information exists elsewhere, but it falls into that category of something I do just often enough to forget how to do it. So, if you find yourself needing to see which objects have been recently deleted from a domain, you can follow these...

One of the things I noticed between RTM and SP1 for Exchange 2010 is the changes made to the RBAC environment, specifically the introduction of many new parameters on individual role entries (cmdlets associated with a role). Using the shell to manage...

With the introduction of Role Based Access Control in Exchange 2010, it seems we have a lot of options for delegation. About 38,505 if you consider drilling down to the attribute level. If you've been tasked with creating a delegation model, it might...

Having been through a few Exchange 2010 deployments, I've had plenty of questions without so many well documented answers. In many cases, I am merely seeking the validation of a simple premise. In this case, my question is, "what is a client access array...

The answer, it seems, is only from Windows Unified Data Storage Server 2003, which goes by so many other names, it can be challenging to understand sometimes. However, the Single Instance Store, which is based on the Exchange and WDS technologies, detects...

I was working with an education customer this week when I came upon an interesting problem related to mail routing for a specific user. This user was migrated from one domain to another and mailbox-enabled for the new Exchange 2007 environment after their...

I've been working through an interesting situation with one of my customers during the past couple of weeks. For some reason, everytime Outlook 2007 clients attempted to download the offline address book (OAB), they would error out. We found a lead at...

One goal at many universities has been to provide a collaboration solution for students, based on email. To do this in Exchange, an administrator needs to create a distribution list to represent the class and populate it with the user accounts. Each distribution...

I thought I had posted this information several years ago, but a customer recently contacted me seeking it and I realized it never left the publishing stage. Please note that this post is more specific to 5.5 to 2003 migrations, but may still be relevant...

This post consists of some notes that I took during the installation of Exchange Server 2007 SP1 (Integrated) into a Windows Server 2008 Active Directory Environment (green field, clean installation of everything). The AD environment was created on RC1...

Every now and then, I take a break from federated infrastructure to post something that is likely only relevant to me. I recently purchased a new sound card (Creative Soundblaster X-Fi Extreme Audio) for a machine that is still running Windows XP. I allowed...

I am working with two independent customers. Each of these customers is running Exchange 2003 on the backend, but have been working over the last several months to upgrade their clients to Office 2007, including Outlook 2007. In most cases, desktops were...

Per knowledge base article 936197 , Exchange 2007 may be dropping recipients from the Offline Address book and generating any of the following errors in the event log (note that diagnostic logging on the Exchange server needs to be set to High or Expert...

I thought I would share some code I wrote for doing bulk mailbox cleanups on Exchange 2003 for cross-organizational mailbox moves. This code is nearly identical to that in my previous post , but this one takes an input file to process several mailboxes...

Although the mailbox was moved to the target Microsoft Exchange server, an error occurred while the policies were being applied. Proxy address policies, Unified Messaging settings, managed content settings, and Exchange ActiveSync settings may not be set correctly. There is no primary SMTP address....

Okay, so this has nothing to do with federated infrastructure, except that many of my customers have or are considering Zunes. I have one and I have what I believe to be a common problem. My music collection contains some content that may be inappropriate...

I've seen a number of posts on other blogs talking about the new features of Exchange 2007 and the ability now to move mailboxes across organizations. I currently have a customer engaged in a major consolidation of multiple Exchange 2003 organizations...
