Problem description:

After coexisting lync 2013 with the existing lync 2010, it is found that the user cannot join the meeting created by the user registered on the 2013 pool, and the user will receive the error message "some sharing features are not available due to server connection problems."

Solution:

Check the lync 2013 front-end event log and find the following error:

Source: LS MCU Factory

Date: 09/04/2013 17:22:32

Event ID: 51048

Task Category: (1021)

Level: Error

Keywords: Classic

User: N/A

Computer: fe2013-1.domain.local

Description:

McuFactory could not find the pool associated with one of the conference directories.

Failed to read pool FQDN associated with conference directory 5.

Cause: The pool associated with the conference directory does not exist anymore.

Resolution:

Conference directories without a valid pool associated can be deleted using management tools.

How to fix it?

Run the command "Get-CsConferenceDirectory" and you can see the conference directory we are using.

As you can see from the output above, the conference directory still exists in the old OCS 2007 R2 environment (BackCompatSite). BackCompatSite was removed from the Lync 2010 topology a long time ago, so I'm not sure why it's still referenced. Now we can see that it has the same identity as the error on the Lync 2013 FE server (unable to read the pool FQDN associated with conference directory 5). To solve this problem, I deleted the BackCompatSite conference directory (where 5 is the identity of the conference directory I want to delete) by running the following command:

Remove-CsConferenceDirectory-Identity 5-Force

After restarting the Lync 2013 FE server, users can create and join meetings. From this solution, it seems that Lync 2010 supports this old BackCompatSite conferencing directory, but Lync 2013 does not!
