Exchange – Event ID 106 – Performance Counter Updating Error

Here’s just a quick post on removing the Event ID error 106 from your application logs on Exchange Servers.

You will properly at some point see the following in your event log:

ID: 106
Level: Error
Source: MSExchange Common
Machine: -
Message: Performance counter updating error. Counter name is Per-Tenant KeyToRemoveBudgets Cache Size, category name is MSExchangeRemotePowershell. Optional code: 3. Exception: The exception thrown is: System.InvalidOperationException: The requested Performance Counter is not a custom counter, it has to be initialized as ReadOnly.\

Disabled/Disconnected mailboxes with PowerShell

Have you ever wanted to get all disconnected mailboxes from Exchange?

Here is a “short” PowerShell syntax, for exactly that:

Get-ExchangeServer | Where-Object {$_.IsMailboxServer -eq $true} | ForEach-Object { Get-MailboxStatistics -warningAction silentlyContinue -Server $_.Name | Where-Object {$_.DisconnectDate -ne $null}}

1	Get-ExchangeServer \| Where-Object {$_.IsMailboxServer -eq $true} \| ForEach-Object { Get-MailboxStatistics -warningAction silentlyContinue -Server $_.Name \| Where-Object {$_.DisconnectDate -ne $null}}

It checks only the mailbox servers in your Exchange farm, and finds the disconnected/disabled mailboxes.
