EXOSharedMailbox: Invoke-DscResource -Test: Resource not found

[fasteiner]

Description of the issue

Until version 1.24.117.1 I did not get this error, since version 1.24.221.1 I get the following error:

code:

` $sharedMailboxConfig = @{ Name = 'EXOSharedMailbox' Property = @{ DisplayName = $displayName Alias = $json.mail.trim() PrimarySMTPAddress = "$($primarySMTPAddress.trim())" EmailAddresses = @("$($json.mail)@tttech365.mail.onmicrosoft.com", "$($json.mail)@tttech365.onmicrosoft.com") Ensure = ($json.requestType -like "delete")? ( "Absent" ) : ( "Present" ) ApplicationId = $env:APPREGID TenantId = $env:AzureTenant CertificatePath = $env:CERT_CONTENT CertificatePassword = (New-Object System.Management.Automation.PSCredential -ArgumentList "CertificatePassword", $password) } ModuleName = 'Microsoft365DSC' #Verbose = $true } Invoke-DscResource @sharedMailboxConfig -Method Set | Out-Null

`

I rolled back to Version 1.24.117.1 for now.

Curiously the problem only exists when creating new resources, as I applied a configuration to a existing mailbox, it worked

Microsoft 365 DSC Version

1.24.221.1 + 1.24.228.1

Which workloads are affected

Exchange Online

The DSC configuration

$sharedMailboxConfig = @{
        Name       = 'EXOSharedMailbox'
        Property   = @{
            DisplayName         = $displayName
            Alias               = $json.mail.trim()
            PrimarySMTPAddress  = "$($primarySMTPAddress.trim())"
            EmailAddresses      = @("$($json.mail)@tttech365.mail.onmicrosoft.com", "$($json.mail)@tttech365.onmicrosoft.com")
            Ensure              = ($json.requestType -like "*delete*")? ( "Absent" ) : ( "Present" )
            ApplicationId       = $env:APPREGID
            TenantId            = $env:AzureTenant
            CertificatePath     = $env:CERT_CONTENT
            CertificatePassword = (New-Object System.Management.Automation.PSCredential -ArgumentList "CertificatePassword", $password)
        }
        ModuleName = 'Microsoft365DSC'
        #Verbose    = $true
    }

Oils you share the outcome of get-DscResource for this resource?

What do you mean by "Oils you share"? @andikrueger

[andikrueger]

Could… obvious typo on my end.

As I rolled back the server (need a working version for prod), I can only provide the output from my own machine:

We are not able to replicate on our end. Curious if you get the same results with PowerShell 5?

[fasteiner]

I just ran it interactively in Powershell 7 - works fine, when I launch it from Jenkins it does not find the resource - very curious.

[fasteiner]

Ahhh I found the issue:

works fine: Invoke-DscResource @sharedMailboxConfig -Method Set

throws the mentioned error: $state = Invoke-DscResource @sharedMailboxConfig -Method Test

can you replicate that? @NikCharlebois

[fasteiner]

Seems to happen with other resources as well:

[fasteiner]

seems this occurs when Invoke-DscResource is run multiple times

[fasteiner]

Temporary Workaround: run every single command in a child job, to have a new context everytime

[fasteiner]

@NikCharlebois any updates?
