Hi there, I need to add the "Full Control" permission for the mailbox owner's account, to their own mailbox. I need to do this for all users. We have a third party application that requires this (the SELF permission is not enough). Is there an EMS command that I can run to achieve this? I know I need to use a combination of get-mailbox & add-permission but I'm not sure how to achieve what I require. Cheers, Sotty_Sydney

Something like this should work but I haven't tested it: $Mailboxes = Get-Mailbox -ResultSize Unlimited ForEach ($Mailbox In $Mailboxes) { $Identity = $Mailbox.Identity $UserID = $Mailbox.SamAccountName Add-MailboxPermission -Identity $Identity -User "DOMAINNAME\$UserID" -AccessRights FullAccess -InheritanceType All } You should test it on one mailbox first with this change: $Mailboxes = Get-Mailbox -Identity "Mailbox Name" ForEach ($Mailbox In $Mailboxes) { $Identity = $Mailbox.Identity $UserID = $Mailbox.SamAccountName Add-MailboxPermission -Identity $Identity -User "DOMAINNAME\$UserID" -AccessRights FullAccess -InheritanceType All } Good luck!Ed Crowley MVP "There are seldom good technological solutions to behavioral problems."
