Sent Items missing in Outlook 2003/Exchange 2007

August 31st, 2011 No comments

Some of our users were logging helpdesk tickets complaining about some of their sent items were missing from their sent items folder.

After looking in eventviewers and message tracking logs, all emails were delivered without a problem. I tried disabling outlook-rules and using various outlook switches like cleanviews and cleanrules, only to see them vanishing from the sent items folder. 

Another odd thing was, that the sent items were only disappearing if the user requested a read receipt.


After troubleshooting for some hours, I found that the affected users were all using a different DelegateSentItemsStyle.  These users were sending emails on behalf of other users and wanted the sent items to appear in the mailbox of the user and not in the mailbox of the delegate.  According to MS KB articles and this involved installing a Outlook 2003 hotfix package and adding a registry key.  Which I configured some weeks ago for a set of users.

After some more googling I found there was a bug in the Outlook hotfix package office2003KB953803GLB.

This bug is fixed in Outlook hotfix package office2003KB959628GLB

After installing this hotfix all new sent emails showed again in the users sent items folder.

Prepare AD, Install Topo and define a Front-End pool

August 12th, 2011 No comments

After preparing the environment we are ready to start the installation of Lync 2010.

Please keep in mind that the names and ip’s are fictive in this documentation.

In this setup I choose to install Archiving and Monitoring on seperate hardware. Also keep in mind that you first have to prepare thes servers the way I described in part 1.

If you need more information or if you have questions please send an e-mail to and I will reply or help you as soon as possible.


Prepare Active Directory Domain Services for Lync Server 2010

The next area for preparation is Active Directory Domain Services. Preparing AD DS for Lync Server 2010 consists of three steps:

· Schema Preparation

· Forest Preparation

· Domain Preparation

Each of these steps can be performed by using the Lync Server Deployment Wizard or the Lync Server Management Shell cmdlets directly.


Install Topology Builder and define Topology for Lync Front-End Pool

Now we have all of the infrastructure preparation complete, so it’s time to move on to defining the topology for Lync 2010 Enterprise Edition in Topology Builder.

1. Log on to Lync Front-End server

2. Go to Start, click All Programs, click Microsoft Lync Server 2010, and then click Lync Server Topology Builder.

Lync 2010 Enterprise Edition Installation

August 9th, 2011 No comments

This guide will run through a consolidated Enterprise edition install (without voice gateway integration, whereby all roles will be deployed on virtual machines.

The guide will be split up in different chapters.

The first chapter is all about preparing your Lync 2010 environment.


Prepare the Lync 2010 Enterprise Edition Server Infrastructure

The following sections outline the step to prepare the Lync 2010 Enterprise Edition server infrastructure.

1. Set Up Enterprise Edition Hardware and System Infrastructure

2. Install Prerequisite Software

· Lync Server requires Microsoft .Net Framework 3.5 with SP1.

· Prerequisite software for database servers.

· Message Queuing. Message Queuing (also known as MSMQ) role components and Directory Service Integration should be installed on the Front End Server, the Archiving Server, and the Monitoring Server if you plan to deploy the Lync Server 2010 Archiving or Monitoring Server roles. The Message Queuing components can be found in Server Manager or can be deployed by using servermanagercmd.exe or the Add-WindowsFeature Windows PowerShell cmdlet.

· Configure IIS:

Role Heading

Role Service

Common HTTP features installed

Static content

Common HTTP features installed

Default document

Common HTTP features installed

HTTP errors

Application development


Application development

.NET extensibility

Application development

Internet Server API (ISAPI) extensions

Application development

ISAPI filters

Health and diagnostics

HTTP logging

Health and diagnostics

Logging tools

Health and diagnostics



Anonymous authentication (installed and enabled by default)


Windows authentication


Client Certificate Mapping authentication


Request filtering


Static content compression

Management Tools

IIS Management Console

Management Tools

IIS Management Scripts and Tools

· Install the Remote Server Administration Tools

· Install Silverlight

Silverlight is required to run the Lync Server Control Panel. Although we won’t be using the Control Panel until everything is installed, you can install it now since we’re installing the prerequisite software. Silverlight needs to be installed on the Front-End servers.

· Install and Configure SQL Server

Lync Server 2010 leverages SQL Server for the back-end database and the Archiving and Monitoring databases. SQL Server needs to be installed before we can install Lync Server 2010. For this lab, SQL Server 2008 with Service Pack 1 will be used, and installed on the Back End Server as well as the Monitoring/Archiving Server.

3. DNS records

Lync Server 2010 leverages DNS for various features. Certain DNS records are required as part of the infrastructure preparation. Each server within this lab will already have an A record in DNS. This is attributed to the fact that I am using Active Directory-Integrated DNS, which has Dynamic DNS enabled by default. However, there are additional DNS records that are required before we proceed, including:


IP of Front End Server


IP of Front End Pool


IP of Front End Pool


Port: 5061

4. Grant Administration Permissions

Follow these steps to grant Administration permissions:

1. Ensure you are in the Users Container in Active Directory Users and Computers.

2. In the details pane, locate the CsAdministrator group, right-click on it, and select Properties.

3. On the CsAdministrator Properties page, click on the Members tab.

4. Click Add.

5. On the Select Users, Contacts, Computers, Service Accounts, or Groups dialog box, type Administrator in the Enter the object names to select field, and then click OK.

6. On the CsAdministrator Properties page, click OK.

5. Create the Lync File Share

The user account that we will use to publish the topology must have full control (read/write/modify) on the file share in order for Topology Builder to configure the required permissions. Because I’m going with an Enterprise Edition deployment, the file share cannot be located on the Front End Server. As a result, We prefer to create the file share on the Monitoring/Archiving Server.

Log on to Lync Monitoring/Archiving server

2. Go Start, click Computer, and then click Local Disk (C:).

3. Right-click in the Details Pane, select New, and then select Folder.

4. Name the new folder LyncShare.

5. Right-click on the LyncShare folder, select Properties, click on the Sharing Tab, and then click Advanced Sharing.

6. On the Advanced Sharing dialog box, select the Share this folder option, leave the Share Name field as LyncShare.

Rename AddressList through EMC does not change the DisplayName in the AddressBook

August 8th, 2011 No comments

When renaming a custom addresslist in exchange 2007 through the EMC, the rename is not visible in the addressbook.  This is because the addressbooks in Outlook use the DisplayName. 

Solution: Change the DisplayName of the addresslist with PowerShell.

Get-addresslist “name” | set-addresslist –Displayname “name”


Another happy day in Powerhell

Lync 2010 NTLM Client Authentication Mismatch

August 1st, 2011 No comments

After installing Lync at one of our customers we experienced the following problem when the user was trying to log in.

When I try to make the remote sign-in with the appropriate credentials, Lync reports me “Cannot sign in to Lync. Lync was unable to sign in. Please verify your logon credentials. But it only happened on Windows XP/Windows 7 machines.

When I try to sign-in using the same credentials and Windows 2008 R2 as the client, Lync is signin in!

TheLync server was running Windows 2008 R2. With Windows 7 and Windows 2008 R2, 128-bit encryption is (by default) required for all NTLM authentication requests. After disabling the 128-bit encryption requirement using information from and running a gpupdate the computer was able to authenticate successfully.
