Note: process name can be different depending on what process accessed the object
Resolution:
Generally recommended solution in MS Article “One or more Objects properties are pointing to Active Directory deleted objects” solves the issue except if on the object in question has the msExchHomeServerName attribute point to an Exchange server which no longer exist.
In this case running Get-Mailbox <Alias> | Update-Recipient has no effect.
To resolve the issue when both homeMTA and msExchHomeServerName attribute have invalid values, run:
$MBX = Get-Mailbox -Identity ‘Doe, John’
Set-Mailbox $MBX -Database $MBX.Database -Confirm:$true -Force -Verbose
Note: alert might not be cleared in SCOM up to 24 hours
