Powershell - How to list the 'Cannot find an object with identity' names and info, e.g. user names no longer in AD

Hi all,

I want to run a script with a large number of user names to see if enabled using something like: 'Get-Content C:\users.txt | Get-ADUser | select SamAccountName,Enabled | Out-File C:\AcctStatus.csv' BUT I also want it to report on the ones that are no longer in AD rather than just getting the errors of cannot find an object with identity, how can I get them added in to the text file with some kind of output e.g. 'field not found' please?
