My Csv file:

"MessageId","MailboxName"
"<HE1P192MB018554247E4F4A81D830F19DD1820@HE1P192MB0185.EURP192.PROD.OUTLOOK.COM>","email@domaion.com"

So my question is. Is it my code there is an error in, or is it in the Exch-Rest tool ?

Hope anyone knows how to fix this .

Have a really nice day!

Answer 1

"Is it my code there is an error in, or is it in the Exch-Rest tool ?" It's you. It's almost always you. That's half of why bugs in external libraries are so hard to find :)

Where do you initialise your $Mailbox variable? If it's from your CSV file, then you should use

$message.MailboxName
$message.MessageID
