How can I fix this simple script in Powershell?

Question

Hi All,

I am really new to PowerShell and have been trying to create my first ever script. It is a script to find out which mailboxes a user has access too

this is what I have so far:

$input1 = Read-Host Please your LBB email address
Connect-ExchangeOnline -UserPrincipalName $input1
$input2 = Read-Host Please enter users username
Get-Mailbox | Get-MailboxPermission -$input2 -ResultSize unlimited

It works well up until this point:

Get-Mailbox | Get-MailboxPermission -$input2 -ResultSize unlimited

I'm not sure what I'm doing wrong but doing these steps manually harbours a successful result maybe because i disregard the $inputs manually - I assume its an issue with these.

Please help haha

Answer 1

The variable $input2 isn't the NAME of a parameter, so don't place a hyphen in front of it.

Like this:

$input1 = Read-Host "Please your LBB email address"
Connect-ExchangeOnline -UserPrincipalName $input1
$input2 = Read-Host "Please enter users username"
Get-Mailbox | Get-MailboxPermission $input2 -ResultSize unlimited   # don't place a hyphen in front of $input2. It's not a parameter name!

Answer 2

If you're going to pipe the results of Get-Mailbox, then use $input2 as the value of positional parameter 1 (i.e., -Identity) and remove the $input2 from the Get-MailboxPermission cmdlet:

Get-Mailbox $input2 | Get-MailboxPermission -ResultSize unlimited

You really don't need the "-ResultSize unlimited" on the Get-MailboxPermission. There shouldn't be more than one match for $input2.
