Requirements for accessing Exchange mailboxes

Backup Exec must have access to a uniquely named mailbox within the Exchange organization for Information Store operations, depending on how the backup and restore jobs are configured.

Access to a uniquely named mailbox is required when you do the following:

  • Back up individual mailboxes separately from the Information Store (also called the legacy mailbox backup method).

  • Configure a backup job that has all of the following settings:

    • A device other than a backup-to-disk folder is the destination device.

    • The Granular Recovery Technology option is enabled.

    • A backup method other than a snapshot method.

  • You restore mailboxes and public folders.

You must use a Backup Exec logon account to connect to the Exchange server when you select mailboxes or public folders for backup. Backup Exec attempts to find a mailbox with the same name as the user name that is stored in the Backup Exec logon account.

If you use a Backup Exec logon account that stores a unique user name and has a corresponding mailbox with the same name, then you are not prompted for an additional logon account. Otherwise, you must choose or create a Backup Exec logon account that stores the name of a unique mailbox within the Exchange organization.

A unique name does not share the first five characters in another mailbox name. For example, if EXCH1 is entered as the mailbox name, and there is another mailbox name such as EXCH1BACKUP, then Backup Exec cannot accept the name. You are prompted to choose another mailbox name.

You can choose or create a logon account that meets any of the following requirements:

  • A logon account for which the user name matches a unique mailbox name.

  • A logon account that uses a unique alias to a mailbox. The user account that connects to the Exchange Server must also have access to this mailbox.

  • A logon account that uses the full computer name for a mailbox. The user account that connects to the Exchange server must also have access to this mailbox.

    An example of a full computer name is:

    /O=Exchange_Organization/OU=Administrative_Group/CN=Recipients/CN=mailbox_name
