In Administrative Tools > Management API > Job Results you can find a listing of all job results for the period configured under Keep Recent Results. This listing can be filtered by period and result.
By double clicking a table entry further details of the job results can be retrieved.
Important notice: Depending on the number and frequency of jobsto be executed as well as the retention period of job results, you may notice a rapid growth of MailStore's master database. Therefore it is not recommended to set a too long retention period for job results (default: 1 week).
