Overview
I have a structure three virtual servers, all running Windows Server 2008 R2 Service Pack 1. The HM01 machine is domain controller and Enterpeise CA, the server HM02 in installed Lync Server Standard with Cumulative Update 4 and Hm03.home.intranet is an Exchange Server 2010 Service Pack 2.
In preparing the environment used to update the guides
Update Lync Server Pool with Cumulative Update 4
The integration between Exchange and Lync was used Article
Integrate OWA Exchange Server 2010 with Lync
Symptom
When users logam in
Outlook Web Access
user status remains Offline, and the error message on the site of contact Lync.
Instant Messaging is not avaible right now. The Contact List Will Appear When the service Becomes avaible.
This error can have several causes. Below I list the main mis-configurations and scenarios reported in the
forum Lync Server
Cause
To check the error using the tool
Logging Tool
Lync Server.
Select the component
SIPStack
and capture all events from this component click
Start Logging.
Log on to Exchange OWA, stop capturing and press
Analyze Log Files
. This screen was taken from a successful connection, the user's contacts were listed and their status updated.
Check the Settings
During configuration is created in a Lync Server
TrustedApplicationPool and
a
TrustedApplication.
The figure below shows the configuration on the left Lync Server, and right print a digital certificate installed on the Exchange and configured for communication with Lync Server.
In
TrustedApplication
the field
TrustedApplicationPoolFQDN
must be configured with the same name that the
Subject Name
of the certificate of the Exchange Server. During the connection the server
Front End
verifies the certificate name and the name used in connection configured in the
Application Pool.
If the names are different fqdn's the connection is denied.
Cause
The
Logging Tool
capture the following error when logging a user in
Outlook Web Access
The field
Date:
*. home.com.br
shows that a wildcard certificate is installed on Exchange Server. This type of certificate is not supported for this scenario.
Another scenario is the use of a digital certificate on the Exchange and Lync, I found nothing in the official literature of the solutions on this scenario but in my test environment the connection failed with the same above error . Here the proposed solution for the two configurations
Solution
Access the console of the Exchange Server tab
Server Configuration
select the server and install a new digital certificate, use the same certificate used for the certificates installed on Lync Server.
In this case I have a wildcard certificate installed and configured to respond in the services
IIS and SMTP.
The new certificate need not be configured in any Exchange service.
Open the
Exchange Management Shell
and run the cmdlet:
Get-OwaVirtualDirectory | Set-OwaVirtualDirectory -InstantMessagingServerName <Lync Server Front End> -InstantMessagingCertificateThumbprint <Certificate Thumbprint used in Client Access> -InstantMessagingEnabled $true -InstantMessagingType 1
For the settings to take effect you must restart IIS. Run the command
IISReset
to restart the service.
