After performing a complete backup of a Microsoft Exchange 2007 Server, additional backups may fail with an AOFO initialization error.

Exact Error Message
aofo: initialization failure...0xe000fed1: an error occurred querying the writer status

Details:

Backup Exec 11d for Windows Servers version uses Microsoft Volume Shadow Copy Service (VSS) to perform backups of Exchange data. These backups initialize and run the Microsoft VSS provider and Exchange VSS writer which may not properly terminate after the backup job is complete.  Once VSS has gotten into this state, backup jobs will fail with:

AOFO: initialization failure...0xe000fed1: an error occurred querying the writer status.

According to the Microsoft document listed below, possible workarounds include dismounting then mounting the Exchange databases using the Exchange Management Console or stopping and restarting the Microsoft Exchange Information Store service.  Please see the Microsoft document for the details of these workarounds.  In addition, the option of using Windows Backup (NTBackup) may be used as an alternative as well as it does not rely on VSS for Exchange backups.
