Change the UPN of a federated user after user has been synced to Office 365

Microsoft strongly recommends to make sure all UPN's needed in Office 365 to be set correctly before doing the initial DirSync.

However in some cases you may want to change the UPN after the initial DirSync anyway, for example:

•  When you're companies history lacks correct user registration (names are not correct);


•  When a user changes their lastname when he/she get's married and wants to use that name when logging in.

In this case it is possible to change the UPN of the user in the federated domain. However again this is not recommended. Here is how you do it.

Five things to reconsider when designing Exchange Server 2010

Five things you don’t do when designing a new Exchange Server 2010 environment.

When it comes to designing a new Exchange Server 2010 environment, a lot of techies think that this isn’t so hard. They just think “Let’s put some servers and install some Exchange roles on it and the job is done”. Especially when installing these servers in a virtual environment like VMware or Hyper-V these things happen. Techies often think hey it’s virtual, therefore my design boundaries are unlimited. Well wrong, wrong, wrong thinking.

Running 64-bit Powershell scripts via SCCM

It kind off started worrying me a bit when i was deploying SCCM 2007 R3 and i wanted to run several power shell scripts that needed to install some Windows Features. I just didn't want to work. Finally after several days, several reinstallations of my test VM, etc, etc i got it working and this is how to do it:

Creating a wildcard webserver certificate with your internal CA

It is possible to create a wildcard webserver certificate using your internal Enterprise CA based on Windows Server 2008 R2. To do this you need to have a Enterprice CA with the webserver template deployed.

The question you'll probably ask yourself is "Why do i need this?". Well the answer is simple. You probably don't want to use this certificate in a production environment, but you can use it for testing purposes without having you to buy a expensive commercial wildcard certificate. Espessially when the test results are having you deciding that a wildcard certificate is not the way to go.

Aanmaken SSL certificaat voor Outlook Web Access via Shell

Om gebruik te kunnen maken van OWA, is het aanbevolen om gebruik te maken van een commercieel SSL certificaat met mobiele ondersteuning. De CSR die aangemaakt wordt in de komende stappen kan gebruikt worden tijdens de aanvraag bij een willekeurige SSL leverancier. Bijvoorbeeld www.sslcertificaat.nl. Hier wordt vervolgens gekozen voor een Comodo Mobile SSL Certificaat.

Libraries in Windows 7

Although this feature in Windows 7 is very handy in accessing your files easy there are some downsides on this feature when deploying it in your organization.

1. If you use the Library feature in Windows 7 on remote files/folders, it requires indexing on the file/folder server which is only supported in Windows Server 2008(R2) or on Windows Server 2003 with Desktop Search 4.0. This is because the library feature needs to have a indexed source folder in order to know where your files are located. To have your Windows 7 client do this, will mean that you need to have 24*7 access to these folders and that's usually not the case.What you can do to have it work is to enable offline folder synchronization on the share you will need to access. This will make a offline copy of the share on the Windows 7 client, so that your client can do the indexing on the folder. Unfortunately this means that you will need a time to time replication to your share on your NAS device.In my understanding i have never seen a third party NAS device with CIFS sharing that can index on your file/folders and have Windows understand it.


2. The library feature is not deploy-able via a GPO. This makes the Central Management of Libraries in Windows 7 a hard one. The philosophy behind Libraries i think is that it's a user feature. If users know what the advantages of properly set libraries are, they will need to create and manage them there own.
