Field Notes: Deploying Office Communicator 2007 R2

Jun 8th 2009Desmond LeeLCS/OCS 2007 R2/ Communicator/ Speech Server/ Mobile & Exchange 2003/ 2007/ 2010/E14 /Forefront

Every new OCS 2007 R2 installation is often accompanied by a number of common issues that most administrators will likely face with deploying Office Communicator Client 2007 R2 (MOC). Let us walk through the steps you might take to configure them correctly in your environment.

1. create domain users and mailbox-enabled the accounts in Exchange*
2. enable the accounts for OCS with the SMTP email address (ideal)*
3. login to the Windows machine and configure Outlook (Autodiscover or manual) before starting MOC for the first time. If the Outlook profile has not yet been created, “Outlook Integration Error” will show up as Notification alerts in MOC (red exclamation or bang sign):
“There was a problem connecting to Microsoft Office Outlook. Your Outlook profile is not configured correctly. Contact your system administrator with this information.”
Make sure that Outlook is running then exit and restart MOC if necessary. For Office 2007 users, apply the patch described in KB936864. Not fixing this error will cause Reverse Number Lookup (RNL) for voice calls to fail, inability to search for Outlook contacts in MOC, presence integration issues, etc.
4. start MOC and “Exchange Connection Error” now appears in place of “Outlook Integration Error”. Click to display details reveals the message:
“Communicator is in the process of connecting to the Exchange server. This process may take a few minutes. Some features will not be available until the connection is complete.”
Depending on network conditions, this notification should automatically disappear after some time and no further action is required.
5. If you see the notification “Cannot Synchronize Address Book”, the details will read:
“Cannot synchronize with the corporate address book. This may be because the proxy server setting in your web browser does not allow access to the address book. If the problem persists, contact your system administrator.”
This must be resolved in order to perform tasks such as fast search (local GAL), click to call number menu display, contact card query details, etc. See the options for possible resolution below.

Suggested Checks and Fixes: Cannot Synchronize Address Book

* use the “Automatically detect settings” instead of specifying settings for a proxy server in IE
* for IE7 under Advanced / Security, uncheck the option “Check for server certificate revocation” and restart the browser (manually or via Group Policy)
* ascertain that the URL listed on the certificate points to the Certificate Revocation List (CRL) Distribution Point that is reachable on the inside and/or outside network
* if OCS is deployed with digital certificates issued from an internal CA, add the .crl URL to the Trusted sites or Local Intranet zone on the Security tab in IE then exit and restart MOC e.g. http://*.swissitpro.ch. This enables the intranet URL for Address Book (AB) download to be recognized as safe and valid.
* deploy certificates from trusted public Certificate Authority (CA) permits both domain and guest (non-domain) accounts to connect to internal OCS pools

* give AD ample time to replicate in the forest/domain

Hi there, this is my first post but thanks for the info on your blog it’s been useful several times. We are seeing the Exchange message you refer to in #4 above. It does go away eventually but it takes about 1 minute after launch. Is this an expected amount of time or would one expect it to resolve more quickly?

Thanks for any info
Mike

Thank you very much for the kind comments and feedback, Mike. It certainly is a great motivation and encouragement knowing that my blog can be helpful.

It really depends on the unique setup and configuration of your network, Exchange, OCS, DNS and AD infrastructure (number of domains, AD sites, etc.), virtualization (if any), network capacity, bandwidth, utilization, etc. AFAIK, there is no hard or fast rules to determine how long it will take to resolve the “Exchange Connection Error” or similar messages. Nevertheless, if it takes more than say 1/2 day for the majority of your users before the message eventually goes away, it is time to (re)look at some of the basics mentioned.

Hope this helps!

Thanks for the info, we have it on about 30 test computers, it takes about a minute regardless of the computer. So that works, thanks for the response.

Mike
