Configuring BitLocker in Intune - Part 2. Automating Encryption

[anyweb]

sure post your updated code here

Thanks for this script/ solution. Thanks to this I learned a lot about how to do BitLocker with PowerShell from Intune MDM. I've added some functionality and made some fixes and design changes, but can't release all the code here due to the fact that I've done this for my company, and it's their IP.

That being said, I'd like to share a fix to one part that failed for me some times: Fetching the certificate for uploading recovery password to Azure AD using REST.
I rewrote it to this, might be usefull for others:

# Get the AAD Machine Certificate
$Certificate           = $([array]$(Get-ChildItem -Path 'Certificate::LocalMachine\My').Where{$_.'Issuer' -match 'CN=MS-Organization-Access'})
$CertificateThumbprint = [string]$($Certificate | Select-Object -ExpandProperty 'Thumbprint')
$CertificateSubject    = [string]$([string]$($Certificate | Select-Object -ExpandProperty 'Subject').Replace('CN=',''))
                    
# Get tenant domain name from registry
$TenantDomain = [string]$([string]$(Get-ItemProperty -Path ('Registry::HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\CloudDomainJoin\JoinInfo\{0}' -f ($CertificateThumbprint)) -Name 'UserEmail' | Select-Object -ExpandProperty 'UserEmail').Split('@')[-1])

 

Offtopic: How do I set a profile picture? I've searched the forum and Google-ed it too.

What happens if the target endpoint has more than one fixed drive? It appears to work fine for the OS Drive, but the secondary drive never attempts to be encrypted. Just curious if there is a way to encrypt all fixed drives (obviously not USB / external storage that happens to be attached). Thanks!

2 questions.

 

1.I just tested this script on a user's pc.  The script pushed fine, and ran and encyrpted the drive, but the recovery key is not in inute/AzureAD.  What can I do to troubleshoot this?

2. If I push this to a user who already has their drive encrypted(different user now) but is only now joining their pc to azureAD/Intune.  Will the script still run and detect that the drive is encrypted and sync the recovery key to intune/AzureAD?

 

Cheers,

what does the C:\Windows\Temp\TriggerBitLocker.log  tell you ?

I haven't tested the second scenario,

I saw the non-user version of the MSI from the original post didn't work anymore, so I uploaded my copies of them just in case anyone still needs it.
