Please help.

Ensure that MSMQ service is installed and running. To verify that MSMQ has been installed, do the following:

1. Click Start and the click Run. In the Run dialog box, type ServerManager.msc and then press ENTER.
2. In Server Manager, expand the Features node. Verify that Message Queuing is listed as one of the installed features. If it is not, click Add Features, then, in the Add Features Wizard, select Message Queuing and click Next to begin the installation of MSMQ
3. Ensure that MSMQ is configured for Directory Services integration.
4. Restart server

If MSMQ is installed then try restarting the service. Simplest way is to just restart the server.

Did you deploy Lync Server 2010 Standard Edition?

If you collocate Archiving role with Lync Server 2010 Standard Edition server, you may have this problem.

If not, please check you have configured and assigned Archiving policies to enable archiving.

Verify that name of archiving Instance because i think it's not correct. this instance in Lync Instance not of Archiving.

Also you can refer below command as example

Export-CSArchivingData -DBInstance lynclab2ma.lynclab2.local\LyncArchiving -StartDate 3/1/2014 -EndDate 3/12/2014 -OutputFolder C:\ArchivingExports
