Lync Exchange Integration Troubleshooting Guide

During some troubleshooting Exchange integration with the Lync Client I discovered that the Lync client uses DNS for finding the Exchange autodisccover location instead of the way Outlook discovers it by SCP in Active Directory.

The problem was that the Lync cliënt could not discover EWS and didn’t update the enhanced presence (out of office and in a meeting). In the Lync configuration information panel it displayed:

“EWS not Deployed”

This guide saved my day and after the creation of the right SRV record it solved the problems!

Integrating Lync Server 2010 and Cisco Unified Communications Manager

The white paper, Integrating Microsoft Lync Server 2010 and Cisco Unified Communications Manager, is now available in the Download Center. This white paper shows step-by-step configuration tasks to set up the Direct SIP connectivity between Cisco Unified Communications Manager (CUCM) and Lync Server.

How to Make Lync Group Chat Client the Preferred IM Client

When both Lync 2010 and the Lync Group Chat client are installed, by default, Lync is the preferred IM client.

When Lync is the preferred IM client :

  • The user’s IM contacts are not displayed in the My Chat pane. Contacts are displayed on the right side of the Group Chat window, in the contacts pane. When you send an IM to a contact, it relays the request to the Lync client. You cannot send an IM to a contact from within Group Chat.
  • Presence for a contact is shown as offline when they are only signed into the Lync Group Chat client.
  • You can make the Lync Group Chat client the preferred IM client.

When Group Chat is the preferred IM client:

  • The user’s IM contacts are displayed in the My Chat pane of the Lync Group Chat window. The user can initiate an IM with a contact directly from the Lync Group Chat client—without launching the Lync client or the Contacts Pane. The My Chat pane displays on the left side of the Group Chat client window.
  • Lync presence shows that the Lync Group Chat user is online, even when she is signed in to only the Lync Group Chat client. This behavior was changed with CU8. See KB article 2488155 Your presence status is incorrect if your default IM client is Office Communications Server 2007 R2, Group Chat.

Perform the following actions to make the Lync Group Chat client the preferred IM client:

1. Add the DisableIM value to the following registry key*. You may need to create the GroupChatConsole and the Permissions keys.

WARNING: Using Registry Editor incorrectly can cause serious, system-wide problems that may require you to re-install Windows to correct them. Microsoft cannot guarantee that any problems resulting from the use of Registry Editor can be solved. Use this tool at your own risk.


2. Add the following DWORD value to the Permissions key:


3. Set DisableIM to 0.

Note:   When this registry modification is made, the Group Chat client becomes the preferred IM client.

4. Exit the Lync Group Chat client, and sign back in to see the changes.


When both the Lync 2010 and the Lync 2010 Group Chat clients are installed, the Lync 2010 client is the default IM client. If needed, you can change the Lync 2010 Group Chat client to be the default IM client.  Setting the Lync 2010 Group Chat client as the default IM client uses the same steps as in Office Communications Server 2007 R2. The exception is that with Lync 2010 Group Chat, the change is included in the communicator.adm file.

Microsoft Lync Server 2010 Web Scheduler

 Microsoft Lync Server 2010 Web Scheduler provides a Web-based online Lync meeting scheduling and management experience for Lync Server 2010.

It provides a Web-based alternative to the add-in for the Microsoft Office Outlook® messaging and collaboration client for the purpose of scheduling a meeting using Lync Server 2010. It also provides a browser-based conference management experience that includes operations such as the following:

·        Scheduling a new online Lync meeting.

·        Listing all existing Lync Server 2010 meetings that the user has organized.

·        Viewing and modifying details of an existing meeting.

·        Deleting an existing meeting.

·        Sending an email invitation to meeting participants by using a configured SMTP mail server.

·        Joining an existing conference.

Compared to the Conferencing Add-In for Microsoft Outlook, Lync Web Scheduler has the following limitations:

·        Lync Web Scheduler does not support scheduling recurring meetings.

·        Lync Web Scheduler lists only meetings that were organized by the user. It does not list all meetings that the user is invited to. Further, meetings created using some other tool will not be editable using Lync Web Scheduler.

·        Lync Web Scheduler is available only in English.

·        Meeting invitations that are generated by Lync Web Scheduler do not look exactly the same as those that are generated by the Conferencing Add-In for Outlook.

·        Lync Web Scheduler doesn’t interact with the calendaring server. Calendar updates happen only via email invitations.
