Just caught wind of a new Communicator hotfix. It brings Communicator up to version 3.5.6907.22.

KB Article 971083 states this hotfix addresses the following issue:

971078 An Automatic Update download is not initiated on a computer that is running Office Communicator 2007 R2 build 3.5.6907.9

According to Matt Wade’s blog, this hotfix also provides compatibility for Exchange 2010. Although at the time of this post, the KB article does not include that information.

970057 Exchange Connection error when you use Office Communicator 2007 R2 with your mailbox in Exchange Server 2010: “Communicator could not retrieve calendar or Out of Office information from Exchange Web Services”

I’ve looked all over the web. I’ve only found 1 way to do this programmatically and it’s a hack at best. You would have to extend this guy’s script to enumerate through all the mailboxes and create the favorites object. Manipulation of these objects is not provided through a supported Exchange API.

The recommended way to do this is to publish detailed documentation for the users to follow.

I was one of the unfortunate who happened to install the update Tuesday night. I followed Scott Roberts’ instructions for fixing the EWS web.config, but I had an additional anomaly. Throughout the entire web.config were randomly scattered NULL characters which had replaced valid characters. So for some people, a find and replace on %ExchangeInstallDir% might not completely solve the issue. Try opening the web.config up in a better text editor that is capable of displaying non-text ASCII characters. I used Notepad++ for this. You will still have to find and fix the NULL characters by hand. See the MS Exchange team blog entry for more info.

I came across this issue at work today. A customer wanted to use a Distribution List to send incoming faxes to an Exchange user mailbox and an Exchange e-mail enabled public folder because the fax to e-mail bridge device was incapable of sending the fax to multiple recipients. After I created the DL Group in AD, I couldn’t add the Public Folder or it’s associated e-mail address as a member. Soon after, I realized that the Exchange objects were not visible from Active Directory Users and Computers. Using Exchange System Manager, I browsed to the Public Folder and added the Public Folder to the Group. It works in the other direction. Checking the membership of the group in Active Directory Users and Computers, I found that the Public Folder was visible as a member.
