Powershell Question

In the following PS what does the ForEach ($MBX in $MBXS) do?

I know that the first $MBXS creates a variable, but is another variable being created? i.e. $MBX ? I often see this. Can $MBX actually be named something else?

$MBXS = Get-Recipient -RecipientType UserMilbox ForEach ($MBX in $MBXS) {
 Add-RecipientPermission $MBX.name -AccessRights SendAs –Trustee <User Principal Name> -Confirm:$False

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years.

Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Yes, it is another variable used for holding a single item from $MBXS array. It can usually be named anything as long as you change any subsequent references.

As you pasted it, it will not work. It needs to be (note the line break):
$MBXS = Get-Recipient -RecipientType UserMailbox
ForEach ($MBX in $MBXS) { 
 Add-RecipientPermission $MBX.name -AccessRights SendAs –Trustee <User Principal Name> -Confirm:$False

Open in new window

The ForEach creates a new (arbitrarily named) var, and fills it with one element of $MBXS (which again is an array of objects).
A simple example is
foreach ($i in 1,2,3,4,5) {  $i }

Open in new window

which goes thru the list of values, and will just dump them to the console.
