Mail-Level backup for Microsoft Exchange Server is not designed to fully protect an Exchange Server, but to facilitate easy backup and fast restoration of individual emails, contacts or calendars, etc. A Mail-Level restoration cannot fully recover the Information Store after a disaster. **Important**: Mail-Level Backup must be utilized in conjunction with full Information Store Backup, in order to fully protect the Exchange Server. ### MS Exchange Server in Data Availability Group (DAG) Exchange Server in Data Availability Group (DAG) provides higher availability for mail items backup and restoration. The Microsoft Exchange Mailbox add-on module is available if you are using Exchange server 2010/2013/2016/2019. Refer to the URL for more details. [https://technet.microsoft.com/en-us/library/dd298065%28v=exchg.150%29.aspx](https://technet.microsoft.com/en-us/library/dd298065%28v=exchg.150%29.aspx) ## Best Practices and Recommendations You are strongly recommended to configure or check all the settings below before you proceed with the Exchange Mail-Level backup and restoration. ### Retrospect Virtual Host Server Installation The latest version of Retrospect Virtual Host Server must be installed on the Exchange Server hosting the database. For Exchange Server 2010/2013/2016/2019, Database Availability Group (DAG) backup option is available, please refer to [Performing Mail-Level Backup for Microsoft Exchange 2010/2013/2016/2019 in Database Availability Group (DAG)](https://www.retrospect.com/en/documentation/virtual_exchangemail_guide#performing-mail-level-backup-for-microsoft-exchange-20102013-in-database-availability-group-dag) for details. ### Retrospect Virtual Host Server Add-On Module Configuration Make sure the Microsoft Exchange Mailbox feature has been enabled as an add-on module in your Retrospect Virtual Host Server user account. Contact your backup service provider for more details. ![image](https://cdn.us.document360.io/6d1fe0c6-ccdb-4ee9-a621-0504cb91b4be/Images/Documentation/exchange-mailbox-guide-image-gnkwnrov.png) ### Scheduled Backup for Exchange Server in Data Availability Group (DAG) Option Scheduled backup is required if you choose to back up in DAG option, as Retrospect Virtual Host Server on all DAG members will base on the scheduled backup time to start backups on individual DAG member at the same time. A DAG backup cycle is considered complete only when scheduled backup on all DAG members have been carried out. An email report will be generated when a complete DAG backup cycle is taken place. Please keep in mind that manual backup will only be considered as individual mail-level backup, and therefore will not be counted as part of the DAG backup cycle. ### Temporary Directory Folder Temporary Directory folder is used by Retrospect Virtual Host Server for storing backup set index files and any incremental or differential delta files generated during a backup job. To ensure optimal backup/restoration performance, it is recommended that the temporary directory folder is located on a local drive with plenty of free disk space. ### Mailbox Access Permission The Active Directory account used for backup must have full access to the mailboxes. To grant full access right for the account, enter the following command in Exchange Management Shell. Open the Exchange Management Shell by clicking **Start** > **Microsoft Exchange Server** > **Exchange Management Shell**. **Exchange Server 2007** Enter the following command in Exchange Management Shell Get-MailboxServer | Add-ADPermission -User "%os_username%" -AccessRights GenericAll -ExtendedRights ms-exch-store-admin,receive-as,send-as -InheritanceType All %os_username% is the username of the operating system account for backup. **Example:** granting permission to local account "system" Get-MailboxServer | Add-ADPermission -User "system" -AccessRights GenericAll -ExtendedRights ms-exch-store-admin,receive-as,send-as -InheritanceType All **Other useful commands:** - To show added permission for an AD account Get-MailboxServer | Get-ADPermission -User "%os_username%" Example, to show added permission for local account "system" Get-MailboxServer | Get-ADPermission -User "system" - To remove permission from an AD account - Get-MailboxServer | Remove-ADPermission -User "%os_username%" -AccessRights GenericAll -ExtendedRights ms-exch-store-admin,receive-as,send-as -InheritanceType All Example, to remove permission from local account "system" Get-MailboxServer | Remove-ADPermission -User "system" -AccessRights GenericAll -ExtendedRights ms-exch-store-admin,receive-as,send-as -InheritanceType All Reboot the Exchange Server after executing the command. **Exchange Server 2010 / 2013** Enter the following command in Exchange Management Shell Get-Mailbox | Add-MailboxPermission -User "%os_username%" -AccessRights FullAccess %os_username% is the username of the operating system account for backup. **Example:** granting permission to local account "system" Get-Mailbox | Add-MailboxPermission -User "system" -AccessRights FullAccess **Other useful commands:** - Remove permission from an AD account Get-Mailbox | Remove-MailboxPermission -User "%os_username%" -AccessRights FullAccess Example: Get-Mailbox | Remove-MailboxPermission -User "system" -AccessRights FullAccess - To view the mailbox permission of a user Get-Mailbox | Get-MailboxPermission -User "%os_username%" Example: Get-Mailbox | Get-MailboxPermission -User "system" Reboot the Exchange Server after executing the command. ### Membership Settings of the Operating System Account The Active Directory account used for the backup must be a member of the following security groups. **Exchange Server 2007** - Microsoft Exchange Security \ Exchange Organization Administrators - Microsoft Exchange Security \ Exchange Servers - Users \ Domain Admins **Exchange Server 2010 / 2013** - Microsoft Exchange Security \ Organization Management - Users \ Administrator - Users \ Domain Admins - Users \ Enterprise Admins **Steps to check the current settings** 1. Click **Start** > **Control Panel** > **Administrative Tools**, and then click **Active Directory Users and Computers**. 2. Browse to the organization unit containing the corresponding operating system account. 3. Right click on the user, and select **Properties**. 4. Select the **Member Of** tab to check on the membership setting. ### Remote Exchange Management Shell For setup on Exchange Server 2010 / 2013, Remote Exchange Management Shell must be enabled for the operating system account used for the backup. Enter the following command in Exchange Management Shell to enable this feature. >Set-User "%os_username%" -RemotePowerShellEnabled $True Reboot the Exchange Server after executing the command. **Note:** Remote Shell in Microsoft Exchange Server enables you to manage your server running Exchange. ### Enabling Mailbox Make sure the account for backup mailbox has been enabled. Follow the steps below to verify. **Exchange Server 2007 / 2010** 1. Click **Start** > **Microsoft Exchange Server 2007/2010**, and then **click Exchange Management Console**. 2. Click to expand the **Recipient Configuration** menu tree, and then select **Mailbox**. 3. Right click on the user and select **Properties**. 4. Select the **General** tab to check the settings.

Download and install the latest version CDO via the URL below. If you already have CDO installed on the Exchange Server but are not sure if it is the latest version, you are recommended to uninstall the current version and re-install via the URL below. **Exchange Server 2007 / 2010** - Exchange Server with MS Outlook 2007: [https://www.microsoft.com/en-us/download/details.aspx?id=3671](https://www.microsoft.com/en-us/download/details.aspx?id=3671) - Exchange Server without MS Outlook 2007: [https://www.microsoft.com/en-gb/download/details.aspx?id=42040](https://www.microsoft.com/en-gb/download/details.aspx?id=42040) **Exchange Server 2013** [https://www.microsoft.com/en-gb/download/details.aspx?id=42040](https://www.microsoft.com/en-gb/download/details.aspx?id=42040) ### LAN Manager Authentication Level **Exchange Server 2013** The LAN Manager authentication level configured on the Exchange Server must be level 3 or above.
