Web Help Desk is down with an email data object error

Updated December 28, 2017


This article describes how to resolve the issue where WHD is down and TRUNCATE EMAIL_DATA_OBJECT gives the following error message:

 The transaction log for database 'WHD' is full due to 'LOG_BACKUP'

    1. Right click WHD Database and select Tasks > Shrink > Files.

    3. Click OK.
  3. Truncate EMAIL_DATA_OBJECT.

Control the growth of EMAIL_DATA_OBJECT

  1. Log in to the WHD Console as an Administrator.
  2. Go to Setup > E-Mail > Options.
  3. Under E-Mail Options, set the Delete E-Mail History Entries After setting to a shorter time period.
