Microsoft Outlook requirements (DS-MLR)
Ensure that the following requirements are met wherever applicable before you create an Email messages backup set to back up Microsoft Outlook data using DS-MLR:
• Ensure that Microsoft Outlook is closed during backup activities. Backup is successful only when Microsoft Outlook is closed.
• If you have configured Microsoft Outlook to use a .PST file on a remote machine, the DS-MLR service must always be installed on the computer with Microsoft Outlook.
• For Microsoft Outlook configured for Microsoft Exchange profiles, the email messages are located on the Microsoft Exchange Server. To access those email messages, the DS-MLR service account must have the Receive-As privilege on that Microsoft Exchange Server. The DS-MLR service account must be recognized on the Microsoft Exchange Server. Otherwise, DS-MLR will return an access denied error.
