Whenever I run the script manually in the task scheduler it works fine and able to output the logfile but when I run it as a scheduled task with setting "Whether user is logged on or not" it doesn't add a log file. it seems like it's not even connecting to graph.
connect-mggraph -TenantId "Tenant_ID" -ClientId "Client_ID" -CertificateThumbprint "Cert_Thumb"
Start-sleep 5
$logfile = "File Path"
Get-MgUserLicenseDetail -UserID "sampleUser" | out-file $logfile -Append

Is the scheduled task using your credential or the default SYSTEM user?
The SYSTEM account, when authenticating, uses the name of your machine (e.g., COMPUTER$) but doesn't provide a password.
You should be including error handling in your scripts (and sometimes transcriptions) and recording any errors the script encounters. Without knowing why something doesn't (or didn't) works without knowing why it failed will lead to very lengthy debugging sessions.
The account that I used in the task scheduler is a service account. I was able to identify the issue because of the error handling
I used this script below since try catch for some reason doesn't work not sure why.
connect-mggraph -TenantId "Tenant_ID" -ClientId "Client_ID" -CertificateThumbprint "Cert_Thumb"
$error | out-file "path" -append
Now my error message is Certificate Thumbprint was not found in Certificate store or has expired
Will research more about this and thanks very much for the advise to add an error handling.!
Bug comment
# Load from local machine store.
$cert = Get-ChildItem Cert:\LocalMachine\My\$CertThumbprint
Connect-Graph -Certificate $cert -TenantId $TenantId -ClientId $ClientId
# Load from path.
$password= "SomePassword"
$passwordSecure = ConvertTo-SecureString -AsPlainText -Force $password
$cert = New-Object System.Security.Cryptography.X509Certificates.X509Certificate2("C:\Certificates\mycert.pfx", $passwordSecure)
Connect-Graph -Certificate $cert -TenantId $TenantId -ClientId $ClientId
I got this script from this thread and it resolved my issue where Certificate can't be read. Thanks very much for the advise of add an error message, might take longer to debug the issue without your advise.

Does the Connect-Graph accept the parameter "-ErrorAction STOP"? You need that to turn a non-terminating exception into a terminating exception. The "Catch" block is entered only for terminating exceptions.
Hi, it doesn't accept the -errorAction Stop. Will figure this out if I need to produce some error logs with Connect-mggraph. What I did was the basic $error | out-file $path and it helped.
