How to disable IMAP/POP3 globally but excluding a specific mailbox?

Hi Vasil,

Thank you for your reply. Below is the scrip that I found online and tested and it works. It will disable IMAP/POP for all mailboxes. If I want to exclude mailbox abc@abc.com in this script, can you help me to modify the script?

$IMAPMBX = Get-CASMailbox -ResultSize Unlimited | ?{($_.ImapEnabled -eq $true) -or ($_.PopEnabled -eq $true)}

$IMAPCount = $IMAPMBX.count

If ($IMAPCount -gt "0") {

    ForEach ($I in $IMAPMBX) {

        $UPN = $I.PrimarySMTPAddress

        $Alias = $Identity

        "--------[IMAP/POP Disable]Start Processing IMAP/POP Disable for Mailbox $UPN--------" | Out-File -Filepath $Logpath2 -Append

        try {

            $error.Clear()

            write-host "Disable IMAP/POP for mailbox $UPN" -ForegroundColor GREEN

            "Disable IMAP/POP for mailbox $UPN" | Out-File -FilePath $LogPath2 -Append

             Set-CASMailbox -Id $UPN -IMAPEnabled $false

             Set-CASMailbox -Id $UPN -POPEnabled $false

        }

        Catch {

            write-host "ERROR - Disabling IMAP/POP for $UPN" -ForeGroundColor RED

            "ERROR - Disabling IMAP/POP for $UPN" | Out-File -FilePath $LogPath2 -Append

            $error | Out-File -FilePath $LogPath2 -Append

        }

    }

}    

Thanks in advance!
