This one has come in handy a number of times. With this simple command, you can use Powershell to update a user’s OOO message.
Set-MailboxAutoReplyConfiguration -Identity user@example.com -AutoReplyState Enabled -ExternalMessage "message with whatever autoreply" -InternalMessage "internal something autoreply" This was a scriptlet that got heavy use on servers and even in our RMM. It can report back services on Windows servers and desktops are are in the Stopped state that are set to Auto or Enabled.
GWMI is short for Get-WmiObject
GWMI win32_service -Filter "startmode = 'auto' AND state != 'running'" | select DisplayName, Name, StartMode, State, ExitCode | ft -autoThis script came in handy for various purposes! I used this in my RMM tool to report on how many and where PST files may be lying. This was helpful for machines that were re-used. You can narrow down the folder list using the path command.
gci -path c:\ -recurse -include *.pst -erroraction 'silentlycontinue'|select-object fullname,lastwritetime | fl fullname This one came in handy A LOT for on-prem Exchange servers. Track down recipients by domain.
get-messagetrackinglog -start "11/29/2023 12:00am" -resultsize 3000| where {[string]$_.recipients -like "*@domain.com*"} This is a little script / scriptlet I came up with when working at my old MSP. We unfortunately had employees who had the tendency to create snapshots in Windows Server and Hyper-V and then leave them. For long periods of time. As in months and even a year plus. These snapshots would grow and of course be a pain in the butt to merge and get rid of.
I ran this in our RMM tool and was able to set an alert or report to it. If there are no snapshots, it exits successfully (Exit 0). If there are snapshots, it says how many there are and exists with a code 1001. You can then have your RMM or log checker alert on that code.
$results=get-vmsnapshot -vmname * | Select VMName, Name, CreationTime
$count=$results | measure | Select Count
If ($count.Count -eq 0)
{Write-Host "No snapshots found"
Exit 0}
Else {Write-Host $results.VMName 'has' $count.Count 'snapshots'
Exit 1001}
