Hello. I need to perform "Recover Mailbox Data" task on some mailboxes having Exchange Administrator role and Domain Admin role, but get an error message: Cannot log in to source mailbox. What other roles must have my account to perform such a task?

Hi, You need "send as" and "receive as" permissions on the mailboxes. These permissions are denied domain admins by default. Leif

use power shell to achive this in a robust action. Get Mailbox | Add-MailboxPermission -User"your account"-Accessright Fullaccess -InheritanceType all Get-Mailbox | Add-ADPermission -User "your account" -ExtendedRights Send-As Once you have finished performing your administrative tasks: Get Mailbox | Remove-MailboxPermission -User"your account"-Accessright Fullaccess -InheritanceType all Get-Mailbox | Remove-ADPermission -User "your account" -ExtendedRights Send-As

Hi all. Problem is solved. I couldn't restore data from those mailboxes because Exchange System Manager was launched at my workstation. After I started RDP session with my Exchange Server and launched ESM on it - everything worked fine, and there was no need to change any permissions, just as this article stated:http://technet.microsoft.com/en-us/library/aa996155.aspxAnyway, thanks a lot for answers.
