Alerting when my Apple certificates expire in Intune using Azure Automation

One of the things I’m always aware of is certificate expiry, especially the ones used for Apple VPP, if those expire and aren’t renewed in time, you may find yourself factory resetting and re-enrolling again which I’m sure we all want to avoid.

Whilst Outlook reminders are a wonderful thing, there is still an element of user error, plus if you renew early, the expiry is now earlier next year so it’s a bit too manual for my liking.

It’s time to automate!

For this script, I’m going to take the excellent work by Peter van der Woude here and extend it slightly to use an Azure Automation Runbook and email me when a certificate is due to expire.

Let’s start with the Automation Account within Azure

Once that’s complete we want to deploy the required modules to it

In PowerShell Gallery select this module and deploy to Azure Automation:

https://www.powershellgallery.com/packages/Microsoft.Graph.Users.Actions/1.9.6

Once deployed, we can reference it in our script

Next up, we need an AAD App Registration we can use to grab the backups

In Azure AD, create a new app registration:

Within API Permissions grant these roles under MS Graph:

  • DeviceManagementApps.Read.All
  • DeviceManagementConfiguration.Read.All
  • DeviceManagementServiceConfig.Real.All
  • Mail.Send

You’ll note it’s still missing permissions so you now need to click the Grant Admin Consent button

Finally create a Secret and save that, the App ID and the Tenant details to use in the script

Now, back to the Azure Automation Account and click Runbook

Create a new Runbook

Enter the Powershell code below (or grab from here) (update the fields as required for your environment)

.SYNOPSIS
Authenticates to the Graph API via the Microsoft.Graph.Authentication module.

.DESCRIPTION
The Connect-ToGraph cmdlet is a wrapper cmdlet that helps authenticate to the Intune Graph API using the Microsoft.Graph.Authentication module. It leverages an Azure AD app ID and app secret for authentication or user-based auth.

.PARAMETER Tenant
Specifies the tenant (e.g. contoso.onmicrosoft.com) to which to authenticate.

.PARAMETER AppId
Specifies the Azure AD app ID (GUID) for the application that will be used to authenticate.

.PARAMETER AppSecret
Specifies the Azure AD app secret corresponding to the app ID that will be used to authenticate.

.PARAMETER Scopes
Specifies the user scopes for interactive authentication.

.EXAMPLE
Connect-ToGraph -TenantId $tenantID -AppId $app -AppSecret $secret

Click Test Pane to make sure it’s worked

Now we need to publish it once it’s tested ok

Now add a schedule to run it daily

That’s it, you should now be annoyed by daily emails until you renew the certificates!

  1. I was going through your tutorial and I get this error when doing the testing

  2. Great idea, I have not tested the code yet but how will this work if you have several VPP/DEP tokens in your tenant.

    Reply
  3. I cannot get the graph authentication to work. This seems to be the problem with most online scripts I find. They don’t appear to use best practices for authentication in a way that is easy to reproduce and that works in 2022.

    Does your single token connection request work in 2022 without MFA and without certificates? I see conflicting info that says you must use one or both of those things.

    Script error: The remote server returned an error: (400) Bad Request

    Reply
    • Hi, this one uses an App Registration so there isn’t any MFA required. Do you have the app reg configured with all of the required permissions?
      The other option would be to use the MS.Graph.Intune module and replace the invoke-webrequest queries with invoke-msgraphrequest (and connect-msgraph with secret values)

      Reply
  4. I may try the second option. I think I have setup the app registration properly. I wish I could just use a system managed identity, but it seems that feature is too new for anyone to have written a guide.

  5. Hi Andrew

    Great idea
    i have issues getting it to work though

    have tried both the script in the blog (version 1.0.0) and GitHub (version 1.0.1)

    version 1.0.0 works both will send me the mail even if there is more than 30 days (have tried with 360 days)until expiration

    i also edited line 196 with this: Invoke-RestMethod -Method POST -Uri $URLsend -Headers $headers -Body $BodyJsonsend
    as i did not receive a mail regarding DEP until i compared it with PUSH and VPP and changed it

    reports this when run:

    • Hi,
      A 401 error normally means the app reg doesn’t have the permissions it needs to run the command (which is why it isn’t finding any dates). Can you confirm which API permissions it has?

  8. perhaps i havent explained it good enough, my edit was in the Blog version of the script: version 1.0.0

    on the github version 1.0.1i haven’t edited anything other than the “box” UPDATE THESE VALUES

    when i run the github version i recive the error and mails come through, but without the dates wehre the certificate needs to be updated, also, the email is being sent even if there are not more than 30 days until it expire

  9. It works

    i did however need to change line 238 from:
    Invoke-RestMethod -Method POST -Uri $URLsend -Headers $headers -Body $BodyJsonsend
    to:
    Invoke-MgGraphRequest -Method POST -Uri $URLsend -Body $BodyJsonsend

  10. hello,
    was really excited for this but every time i try to test the runbook it fails:

    InteractiveBrowserCredential authentication failed: Unable to load DLL ‘IEFRAME.dll’: The specified module could not be found. (Exception from HRESULT: 0x8007007E)
    The response content cannot be parsed because the Internet Explorer engine is not available, or Internet Explorer’s first-launch configuration is not complete. Specify the UseBasicParsing parameter and try again.

    any ideas? i tried the updated code from github

  11. Hello there, I do have an app reg configured. It’s configured in the code but should the client Id be the name of the client secret or the application Id of the app reg?

    Reply
    • Client ID is the Application Client ID on the App Reg overview screen
      Client Secret is the Secret Value (not the secret ID)

      Check you app permissions as well, forbidden means something isn’t authorized

  12. Yup, I even went through those again last night to double-check:
    API/Permission Name –> Type –> Description –> Admin Consent Required –> Status
    DeviceManagementApps.Read.All –> Delegated –> Read Microsoft Intune apps –> Yes
    –> Granted
    DeviceManagementApps.Read.All –> Application –> Read Microsoft Intune apps –> Yes
    –> Granted
    DeviceManagementConfiguration.Read.All –> Delegated –> Read Microsoft Intune Device Configuration and Policies –> Yes –> Granted
    DeviceManagementServiceConfig.Read.All –> Delegated –> Read Microsoft Intune configuration –> Yes –> Granted
    Mail.Send –> Delegated –> Send mail as a user –> No –> Granted
    User.Read –> Delegated –> Sign in and read user Profile –> No Granted

  14. Hopefully my last dumb question, now it is running and scheduled but the emails are not publishing the expiration date. Will that only show up if it is within 30 days?

    Example:
    Your Apple Push Certificate is due to expire on

    Please Renew before this date

  15. Hi Andrew,

    I’m using version 1.0.4 and getting this error:

    System.Management.Automation.MethodException: Cannot find an overload for “ToString” and the argument count: “1”.

    Any idea what i’m doing wrong?

    • It sounds like one of the variables isn’t being grabbed from Graph.

      If you try an interactive connect-mggraph and then run lines 134-136, what do you get in $pushexpiryplaintext?

      Then do the same for 176-179 and 221-224
