Symptoms

The Exchange backup failed with the following errors:

Subsequent backups reported the same errors.

Cause

The account that had started the Backup Agent (avagent) had an expired password.

This caused the Avamar client to fail performing Exchange specific operations.

Resolution

Setting the password for the Backup Agent account to "Never expired" allowed the backup to complete successfully.

  1. Go to Administrative Tools > Services
