Thanks to Henrick Walter for his article "Exchange Schema Versions - Common Questions & Answers". He describes that you can find your Exchange version by looking to the RangeUpper value in Active Directory Schema (configuration partition).

See article

Unfortunately, I did not find out how to check the Rollup version for Exchange servers. To check this you may read Bhargav's IT Playground blog and its article "How do I check Update Rollup version on Exchange 20xx Server?" Download the mentioned PowerShell Script Get-ExchangeUpdateRollups.ps1 and run it! Works fantastically!

A short backgrounder

If you want to synchronize addresses and free/busy information between multiple Active Directory forests (or multiple Exchange Organizations) in a cross-forest scenario without having a Windows domain trust: then GALsync is the solution for you.

Your user or group objects are created at your partner's sites as contacts and they are displayed in the Global Address List (GAL). GALsync can also synchronize free/busy data

Sets the language attribute of Exchange 2010 mailboxes - use this powershell script

usage scenario: During a move mailbox scenario in a mid-large international company users told that they got Non Deleivery Reports (NDRs) in German language. Crazy, because all servers are set up with English OS and English Exchange Software - no German at all!

Empty all extension attributes and replace the value with NULL for all users with Exchange 2010 mailboxes

usage scenario: During a move mailbox scenario in a mid-large international company we had to empty all extension attributes (formerly called custom attributes). Some attributes still had values from a years ago migration.

First I thought to take ADModify.NET. But unfortunatly you can only replace one attribute at a time. So it would be too time-consuming with that utilitiy.

Modify attributes of users who are listed in a file - use this powershell script

usage scenario: During a move mailbox scenario in a mid-large international company we had to exclude certain users from moving. So we had to "mark" all users, which were Blackberry mobile users and all VIP-users.

Do you like to manage your mailbox accounts by having different Active Directory groups for mailboxes on 2003, 2007 and 2010 servers?

We often have the following problem by our customers:

• OWA Access should be available via a single URL, regardless if there are different Exchange Versions in the organization. Recently the following scenario seems to happen frequently, when one is in the transition phase between Exchange 2003, and/or 2007 to Exchange 2010. The URL call is routed over an ISA/TMG or a CISCO Netscaler, which then checks the group membership of the user to then forward him to the correct Exchange Server URL
• The Organization would like to control various things, depending on which Exchange Server the user has its mailbox on.

To avoid manually adding users to Exchange Groups we developed a small tool which automates this process.

With Outlook 2010 or iPhone OS 4.0 it is possible to access multiple mailboxes / Exchange accounts. There is no need to create multiple Outlook profiles. So the access to mailboxes from different Exchange organizations is possible too.

Introduction

Information workers frequently need to collaborate with external recipients such as vendors, partners, and customers, and share their availability (free/busy) information, calendar, or contacts.

In this third part I will describe the first required configuration tasks and the experiences we made with creating the federation trust using a current Exchange Comodo UC certificate.

Information workers frequently need to collaborate with external recipients such as vendors, partners, and customers, and share their availability (free/busy) information, calendar, or contacts. So we speak about

1.     Federated free/busy sharing
Access free/busy information of an external user in a partner's company. The published Exchange availability service of the partner's company answers directly using the requested information from user's mailbox. No public system folder is used anymore.

2.     Federated calendar sharing
Access calendar information of an external user in a partner's company. The user has to ask the external user to share his calendar by using the features of Outlook or Outlook Web App.

3.     Federated contact sharing
Access private contacts information of an external user in a partner's company. The user has to ask the external user before to share his contacts by using the features of Outlook or Outlook Web App.

In this second part I will give a technical level overview about what Microsoft Exchange Server 2010 Federation services provide and what the limitations are.

You might want to change from using availability service to classic public folder usage for accessing and storing free/busy information.

In diesem Beispiel werden die einzelnen Objekte systematisch erzeugt und miteinander in Verbindung gesetzt: RoleGroup - RoleAssignement - Role.

In einem internationalen Unternehmen sind die lokalen Admins auf OU-Ebene voll delegiert, die erforderliche Benutzerverwaltung zu machen. Die Postfächer für alle Länder liegen in einem Datenzentrum. Auch die Exchange relevante Benutzerverwaltung wird von jedem Land eigenständig erledigt.

Die Überwachung des Postfachzugriffs ist unter Exchange 2007 ab SP2 möglich, in Exchange 2010 standardmäßig integriert. Die Konfiguration kann über den Assistenten für "Diagnoseprotokollierungseigenschaften verwalten..." vorgenommen werden. Dies ist eigentlich ein altbekanntes Feature aus vorigen Exchange Versionen.

Das Database Availablity Group Konzept wird hier am praktischen Beispiel dargestellt.
Es kann als Vorlage für Administratoren dienen, die in einer virtuellen Umgebung Exchange erst einmal "testen" müssen. Ich verwende MS Hyper-V virtuelle Maschinen, um die Datenbank-Verfügbarkeit in Exchange Version 2010 RC zu demonstrieren.

Outlook Web Access / Outlook Web Apps (OWA) : neue Features und was das Herz sonst noch so begehren könnte.
Outlook Web Access in Exchange 2010, seit kurzem von MS in Outlook Web Apps umbenannt, bietet eine Reihe von Features, die gerade für solche Unternehmen sinnvoll sind, die ältere Outlook-Clients verwenden oder viele bestehende OWA Nutzer im Vertrieb oder in Aussenstellen haben. Hier lohnt sich das Server-Upgrade nach Exchange 2010 ohne gleich die Clients migrieren zu müssen.
Im Blog werde ich aufzeigen, was so alles "im Tank" steckt und wie OWA zur Entlastung des Help-Desks / der IT beitragen kann.

Even though Exchange 2010 is not a finished product yet, it seems kind of strange discussing a transition to it at this stage, but there are some things that you should know if you are planning on upgrading your current Exchange environment to Exchange 2010 in the future.
