In order to back up and restore individual Exchange mailboxes or to view mailboxes from a GRT (Granular Restore Technology) based backup, Symantec Backup Exec  for Windows Servers (tm) requires access to a uniquely named mailbox within the Exchange organization. A unique name is one that does not exist in the organization as a subset of characters in another mailbox name. If the mailbox name is not unique within the organization, Backup Exec will not accept the name and you are prompted to select another mailbox name.

To use the Outlook client to confirm that the mailbox selected for Exchange mailbox backups is unique in the Exchange organization:

1. Open Outlook on any server or workstation in the Exchange organization

2. Under Outlook Shortcuts, click Inbox, and then click New to open a new email message (Figure 1)

Figure 1
 

3. In the To box of the Untitled Message, type the first two or three characters of the Exchange mailbox selected for use in mailbox backups, and then press <Ctrl+K>. If the mailbox name is unique in the Exchange organization, the name will be underlined (Figure 2).

4. If the mailbox name is not unique, then the Check Names dialog box will be displayed with multiple mailboxes that share a common subset (Figure 3)

Note: If the Check Names dialog box appears, then the mailbox name specified is not unique, and a different mailbox name must be specified. Please note that the mailbox specified must be associated with a user account that has full rights to the Exchange server, as described in the documents listed in the Related Documents section of this TechNote.
