Bulk add full access permissions for all mailboxes to a user or group

Here is a couple of commands to add full access permissions for all or specific mailboxes to a user or group. The first command adds permissions for all mailboxes in a specific database:

Get-MailboxDatabase -identity "Mailbox database where mailboxes reside" | Add-ADPermission -user "User or group to grant permission" -AccessRights FullAccess

The second command adds permissions to all users in all databases:

Get-MailboxDatabase | Add-ADPermission -user "User or group to grant permission" -AccessRights FullAccess

Or for example if you want to add the permission for the mailboxes with users in a specific OU, use the following command:

Get-Mailbox -OrganizationlUnit "OU where the users reside" | Add-MailboxPermssion -User "User or group to grant permission" -AccessRights FullAccess

Note: You will only change the existing mailboxes, you will have to run the commands again after adding new mailboxes.
