Hi,

Based on my  research, the issue can be resolved by removing and re-creating all Exchange performance counters:
add-pssnapin Microsoft.Exchange.Management.PowerShell.Setup
$files=get-childitem C:\Program Files\Microsoft\Exchange Server\V15\Setup\Perf\" *.xml |where-object {!($_.psiscontainer)}
foreach ($file in $files) {remove-perfcounters -definitionfilename  $file.fullname}
foreach ($file in $files) {new-perfcounters -definitionfilename  $file.fullname}

For more information, you can refer to the following thread:
http://social.technet.microsoft.com/Forums/exchange/en-US/a8e35d2a-5e09-4ec5-b5c8-43554d3b8b78/lots-of-errors-106-msexchange-common?forum=exchangesvradmin

If you have any question, please feel free to let me know.
Thanks, 

I am trying to clean up the 106 event errors but get an error in the script.  Any help would be appreciated.  OI am running Exchange 2013, CU9 over Server 2012 R2, latest fixes.

Tip of the day #52:

Want to know which mailboxes a specific Active Directory user has permissions to? Type:

 $Mailboxes = Get-Mailbox -ResultSize Unlimited
 $Mailboxes | Get-MailboxPermission -User <Active Directory User> | Format-Table Identity, AccessRights, Deny

Caution: This command enumerates all the mailboxes in your organization. If you have lots of mailboxes, you may want to
target specific mailboxes.
