Mailbox Access Via ShellProviding permissions to users’ mailboxes is easy with the Exchange Management Shell. Send on behalf to: MSH>set-mailbox "Joe Contoso" -GrantSendOnBehalfTo "Jim Fabrikam"
Send-As (send as someone else): MSH>add-adpermission "Joe Contoso" -extendedrights Send-As -user contoso\fabrikam
Full mailbox access: MSH>add-mailboxpermission "Joe Contoso" -accessRights FullAccess -user contoso\fabrikam
You can use get-mailboxpermission to see what rights are on a set of mailboxes... in fact, we can finally see who has rights on who's mailboxes in bulk. The commands are fully pipelineable: MSH>get-mailbox -server myserver | get-mailboxpermission |
