Get the subject of a recieved email in PowerShell - powershell

Question

So I'm checking for an approach on a problem I have.
I have an e-mail from my school (Office 365) and I wanted to print the email subject of each email that's located in my inbox with PowerShell.
I already have found the method to lay a connection
$UserCredential = Get-Credential
$Session = New-PSSession -ConfigurationName Microsoft.Exchange -ConnectionUri https://smtp.office365.com/powershell-liveid/ -Credential $UserCredential -Authentication Basic -AllowRedirection
function Connect-O365 {
$session365 = New-PSSession `
-ConfigurationName Microsoft.Exchange `
-ConnectionUri "https://smtp.office365.com/powershell-liveid/" `
-Credential $UserCredential
-Authentication Basic `
-AllowRedirection
Import-Module (Import-PSSession $session365 -AllowClobber) -Global
}
And have found the Get-Mailbox cmdlet.
The problem now however is that I haven't found any real examples or methods that continue to help me printing the email subjects.
I have done quite some research and didn't manage to find something like:
Get-Mailbox -Identity "user" |Select-MailBox * |Where-Object $_.MailBoxName = "Inbox"
Is this not possible or do I have to use another method?

Answer 1

If you have an Office365 subscription you could use the Office 365 api via their graph api endpoint
Since this is basically a REST endpoint you can use the Invoke-Webrequest or Invoke-RestMethod cmdlets.
Or more specificaly the Outlook api.
Both give you json back with you messages content like subject, to, from, and whatever.
