Get-Mailboxpermission for list of Mailboxes

Question

I want to get a list of all permissions for a specified list of mailboxes.

To get all permissions for just one, I can do this:

Get-MailboxPermission -Identity "Mailbox01"

What if I wanted to get a list of permissions for more than one mailbox at a time?

Something like:

Get-MailboxPermission -Identity "Mailbox01","Mailbox02","Mailbox03"

How could I do something like that - in one list?

Answer 1

something like this should work:

"Mailbox01","Mailbox02","Mailbox03" | % { Get-MailboxPermission -Identity $_ }

Have to use a foreach because Get-MailboxPermission doesn't accept [string[]] as pipeline input or you can do:

"Mailbox01","Mailbox02","Mailbox03" | get-mailbox | Get-MailboxPermission

Answer 2

You should first pull a list of the mailboxes needed and pipe into a variable or paste into a .CSV file (I prefer CSV files). Example:

Get-Mailbox -resultsize unlimited   | Where-Object {$_.RecipientType -like "UserMailbox"} | select userprincipalname, ForwardingAddress |out-gridview

$CSV = import-csv "c:\CSV.csv"

$CSV |out-gridview 

$CSV | foreach {get-MailboxPermission -identity $_.userprincipalname} |out-gridview

with the Gridview you can then further sort on multiple values
