Short PS script not working when called via scheduled task
Exchange 2010 SP2 RU3 We have a script created to count the number of mailbox databases that are currently enabled for provisioning, and to generate an email should this number drop below our configured threshold. We use a specific account to run the scheduled tasks from, and we have no problems running it under those credentials within the Exchange shell. We have other scheduled tasks set up similarly that work fine. get-mailboxdatabase 'mailstore_*' | where {$_.isexcludedfromprovisioning -eq $false} | ForEach-Object {$count++} if ($count -lt 4) { Send-MailMessage <etc. etc. etc.>} else { } We schedule the task via a BAT file, which contains the below command PowerShell.exe -executionpolicy bypass -PSConsoleFile "C:\Program Files\Microsoft\Exchange Server\V14\Bin\ExShell.psc1" -Command ". '<path to script file>'" Is it a problem with how the count is done?

Hi @all, I would prefer that you run the task with highest permission! You can enable that when opening the task. Than I would run it as a ps1 file like this: PowerShell.exe -File <Path2File.ps1> In the File you should load the Exchange PSSnapin like this: If ((Get-PSSnapin -Name "Microsoft.Exchange.Management.PowerShell.E2010" -ErrorAction "SilentlyContinue") -eq $null) { If ((Get-PSSnapin -Registered -Name "Microsoft.Exchange.Management.PowerShell.E2010" -ErrorAction "SilentlyContinue")) { Write-Host "Load Exchange PSSnapin" -ForegroundColor Magenta Add-PSSnapin -Name 'Microsoft.Exchange.Management.PowerShell.E2010' } } after that you put your code and I think it will run perfect. If not please post it here... Arne Arne Tiedemann | Active Directory and Exchange specialist

Hi Arne, Thanks for your reply. I added the lines you provided to the script, and it runs fine from the shell. I modified the scheduled task to then launch powershell.exe -file <path to script>, and I see the same behavior when it executes successfully but the email does not get generated. The task is being executes by our normal account and with the checkbox to run with highest privileges. If ((Get-PSSnapin -Name "Microsoft.Exchange.Management.PowerShell.E2010" -ErrorAction "SilentlyContinue") -eq $null) { If ((Get-PSSnapin -Registered -Name "Microsoft.Exchange.Management.PowerShell.E2010" -ErrorAction "SilentlyContinue")) { Write-Host "Load Exchange PSSnapin" -ForegroundColor Magenta Add-PSSnapin -Name 'Microsoft.Exchange.Management.PowerShell.E2010' # Set the Exchange Script path to a variable $EnvEScripts = "C:\Program Files\Microsoft\Exchange Server\V14\Scripts" } } # Generate alert if number of databases enabled for provisioning is below the configured limit of 4. $count=0 get-mailboxdatabase 'mailstore*' | where {$_.isexcludedfromprovisioning -eq $false} | ForEach-Object {$count++} if ($count -lt 12) { $messageParameters = @{ Subject = "Provisioning Database Count Below Limit - $count" Body = get-mailboxdatabase 'mailstore*' -status | where {$_.isexcludedfromprovisioning -eq $false} | select-object name,databasesize,isexcludedfromprovisioning | sort-object name | ConvertTo-Html | Out-String From = "messaging@domain.com" To = "my_smtp@domain.com" SmtpServer = "smtp.domain.com" } Send-MailMessage @messageParameters -BodyAsHtml }

Hi @all, can you add a line for exporting the errors to a File like this: ... snip... get-mailboxdatabase 'mailstore*' | where {$_.isexcludedfromprovisioning -eq $false} | ForEach-Object {$count++} If ($Error[0]) { $error[0] | Out-File -Path <Path2Fil> -append -force if ($count -lt 12) { "I'm in the foreach" | Out-File -Path <Path2Fil> -append -force $messageParameters = @{ Subject = "Provisioning Database Count Below Limit - $count" Body = get-mailboxdatabase 'mailstore*' -status | where {$_.isexcludedfromprovisioning -eq $false} | select-object name,databasesize,isexcludedfromprovisioning | sort-object name | ConvertTo-Html | Out-String From = "messaging@domain.com" To = "my_smtp@domain.com" SmtpServer = "smtp.domain.com" } Send-MailMessage @messageParameters -BodyAsHtml If ($Error[0]) { $error[0] | Out-File -Path <Path2Fil> -append -force } Than you can see if the Script go in to the ForEach and what error comes back.

Hi Did you try above Script. In order to run get-mailboxdatabase CMDLET, you should have both two permisson for the account Organization ManagementServer Management So, could you have a check on that? Cheers Zi Feng TechNet Community Support

You need to run it like below it's by design if you excute using local powershell instead of remote powershell and you run into a split brain permission issue with powershell and task scheduler. C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe -command ". 'C:\Program Files\Microsoft\Exchange Server\V14\bin\RemoteExchange.ps1'; Connect-ExchangeServer -auto; c:\admin\scripts\get-mailbox1.ps1" http://social.technet.microsoft.com/Forums/en/exchangesvradmin/thread/12ffef78-c85a-4831-8d48-0d9f44216dddJames Chong MCITP | EA | EMA; MCSE | M+, S+ Security+, Project+, ITIL msexchangetips.blogspot.com

This was being caused by a corrupt powershell profile file that someone else had copied/modified on the management server where the task was running from.
