How to bulk add Send-As and FullAccess permissions using exchange 2007 powershell using add-adpermission and add-mailboxpermission

Some email administrators have been asking how to add the Send-As and FullAccess permission to many users at once for a particular user account.

Its quite a straightforward command to achieve this, but it should be noted that it is not the Add-MailboxPermission you use, it is the Add-ADPermission for the Send-As rights.

You can easily amend this for adding FullAccess rights in bulk

So, to add Send-As rights for user JoeBloggs to ALL Mailboxes in your organisation:

Get-Mailbox | foreach-object{$mbDN = $_
.distinguishedname; Add-ADPermission -identity $mbDN -User “DOMAIN\JoeBloggs”
-ExtendedRights “Send-as”}

The CSV Approach

And if you have a list of users\mailboxes OR both you wish to process:

Create a CSV with 2 colums. TheMailbox and TheUser

For instance lets say the CSV looks like this:

TheMailbox,TheUser
emp70,emp66
emp71,emp67
emp72,emp68

This will give user emp66 Send-As rights to user emp70′s mailbox, user emp67 to user emp71′s mailbox etc etc

$Thelist = Import-csv “C:\thelist.csv”

ForEach($theobject in $thelist) {$theMBDN = (Get-Mailbox $theobject.the
mailbox).distinguishedname; Add-ADPermission $thembDN -Extendedrights “Send As”
-User $theobject.theuser}

To Add Mailbox ‘FullAccess’ permissions using the CSV approach…

Just a few small changes needed…

ForEach($theobject in $thelist) {$theMBDN = (Get-Mailbox $theobject.the
mailbox).distinguishedname; Add-MailboxPermission $thembDN -Accessrights “FullAccess” -User $theobject.theuser}
