When archived items are restored back to the exchange mailbox, they will be re-archived based on the Archived Date property as opposed to the Sent/Received Date which will extend the length of time based on the archiving policy.

This feature can by bypassed by using the IgnoreEVDates registry key to tell the Archiving Task to ignore this property when evaluating messages eligibility for archiving.



Note: It may be necessary to create the registry keys.

The Archiving Task needs to be restarted for the change to take effect.

Registry key details:


Location: HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\KVS\Enterprise Vault\Agents

Content: DWORD 

0 - Off
1 - Ignore Archived date
2 - Ignore Restored date
3 - Ignore both Archived and Restored date


Controls whether the Archived Date property of items is considered when archiving.In effect, this means that mail items are treated as though they had never been archived.



Location: HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\KVS\Enterprise Vault\Agents

Content: String value containing a UTC date and time in the following ISO 8601 format: yyyyMMddThh:mm:ssZ


Sets the date that the IgnoreEVDates registry value uses as the latest Archived or Restored date.



  • These settings are global and will apply to the whole organization. If only certain mailboxes need to be targeted, a manual run now can be done on those specified mailboxes and the registry key removed after archiving is complete.
  • By design this setting will not apply to non-shortcut type items such as: calendar, contacts, tasks, etc. Refer to 100026773 below for further information regarding this.
  • These settings will only apply during Run Now archiving operations, not during scheduled archiving operations.

These settings are also discussed in the Registry_Values.pdf file found in the Documentation folder of the EV installation directory.
