Reading inbox on a shared mailbox on office365

PowerShell Help
1

Good morning all,

I’m trying to read the inbox of a shared mailbox.
I found this script but cant find a way to change this to a shared mailbox because it doesn’t have a login.
I’m using my own credentials (with rights on that mailbox)

Hope someone can point me in the right direction

# Set how many emails we want to read at a time

# Index to keep track of where we are up to. Set to 0 initially. 
$index = 0 

# Do/while loop for paging through the folder

        '' 
    } 
    # Increment $index to next block of emails
    $index += $numOfEmailsToRead
} while ($findResults.MoreAvailable) # Do/While there are more emails to retrieve

I solved the issue,

 

You can set a password on a unlicensed shared mailbox user,

If you use this the script works
