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)

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!
I was going through your tutorial and I get this error when doing the testing
System.Management.Automation.RuntimeException: You cannot call a method on a null-valued expression.

Hi John,
Thank you, have just updated the script which should hopefully fix this one
Great idea, I have not tested the code yet but how will this work if you have several VPP/DEP tokens in your tenant.
You might need to use a foreach loop to run the notification for each one, probably worth testing though. Happy to help if needed
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
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)
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.
It should be possible, might be worth having a look at this:
https://msendpointmgr.com/2021/07/02/managed-identities-in-azure-automation-powershell/
You should be able to replace the web requests with Graph requests from the module
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?
i have tried a few things so have added a few more permissions
DeviceManagementApps.Read.All
Application
DeviceManagementConfiguration.Read.All
Application
DeviceManagementConfiguration.ReadWrite.All
Application
DeviceManagementManagedDevices.Read.All
Application
DeviceManagementServiceConfig.Read.All
Application
DeviceManagementServiceConfig.ReadWrite.All
Application
Mail.Send
Application
Send mail as any user
User.Read

Which error are you getting now?
still the same, mails come in but with no date

I think it’s your change to 196 causing authentication issues. If you are using Connect-MgGraph, use Invoke-MgGraphRequest instead of invoke-webrequest
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
Can you try 1.0.2 just added to GitHub?
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
Excellent, fixed in 1.0.3 too
hello,
was really excited for this but every time i try to test the runbook it fails:

any ideas? i tried the updated code from github
Hi,
Do you have the app reg configured at the top? It looks like it is trying to do an interactive authentication
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?
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
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
Are they application permissions across the board? Deleted won’t work without a logged in user
ok re-did all permissions and made sure they are app permissions, saved. re-tested:

OK, out of spite for Azure I copied the original and made a brand new runbook. same code exactly, with our info.
it worked. wtf.
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
It should populate the dates before renewal, it just won’t email until then
Hi Andrew,

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

Looks like you have a permissions issue, make sure you have the correct permissions set in your app reg
Permissions of my user that was signed in with powershell was the problem

Please Renew before this date
so maybe I can ignore the error
Do those dates look correct?
What is the value of $pushexpiryplaintext?
$pushexpiryplaintext = $pushcert.expirationDateTime
What is the response returned to it when you run the script?
nothing at all
What about $pushcert?

And this is definitely empty?
$pushexpiryplaintext
$pushcert.expirationDateTime clearly exists in the output
yes it is when I run the powershell command switch powershell
That means the script is working then so it’s something on the runbook side. Double check your app reg permissions and see if the output or errors give any clues
I just Ignore the errors and wait untill the other items will expire. the MDM mails are working. so already happy with that part.
thank you for the script and the support.
Getting Following Error while running the Script.

Can you try v1.0.5 which I have just uploaded
Andrew, where is it?
In the Github repo:

Hey Andrew,
After updating the Scrip I am getting the following error.

It looks like it isn’t authenticating, do you have the app reg configured correctly?
Hi Andrew
do you have a good idea regarding this client secret expiring and perhaps also certificates? so this don’t stop working?
Yes, you can use a runbook or logic app to alert when app reg secrets expire. This will need an app reg of its own of course (with an expiring secret)
