EXOSharedMailbox: Loading of module / connection to ExchangeOnline not proper

[fasteiner]

Description of the issue

Code:
(see configuration below)

	Invoke-DscResource @sharedMailboxConfig -Method Set

Gives me the error:
Set-TargetResource: The term 'New-MailBox' is not recognized as a name of a cmdlet, function, script file, or executable program. Check the spelling of the name, or if a
path was included,
verify that the path is correct and try again.

When issuing this command before the Set it produces the same error:

Connect-ExchangeOnline -CertificateFilePath $env:CERT_CONTENT -CertificatePassword $password -AppID $env:APPREGID -Organization $env:AzureTenant -ShowBanner:$false

However, if I run the connect after the set, then The New-Mailbox command is known. It is impossible to test the set afterwards because of my already open issue: #4434

I tried downgrading a few versions, but this does not solve the issue. The problems presist since we updated to the latest version. Unfourtunatley I did not write down, which version we were on, but it was definitely a few months old.

Microsoft 365 DSC Version

1.24.529.1

        }
