access to a uniquely named mailbox within the Exchange organization
for Information Store operations, depending on how the backup and

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
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.
