Veritas has identified a memory leak when running Microsoft Outlook 2003 SP2 with the Enterprise Vault server or client software. This leak occurs when Enterprise Vault accesses or creates PST files:
  • Client-side PST Migration (Enterprise Vault 6.0 and higher): 4mb for every PST chunk that is populated and uploaded. By default PST chunks are 10,000kb in size.
  • Offline Vault (Enterprise Vault 5.0 and higher): 4mb for every offline Vault database file for the first access and when an item is added to it.
  • Exporting Archives to PST or saving the results of browser search to PST: 4mb for each PST created
  • Importing PST files via the Enterprise Vault Policy Manager, or directly on the Enterprise Vault server.

This issue has been resolved as part of the following Outlook 2003 update:

Veritas recommends if running Outlook 2003 SP2 with the Enterprise Vault server or client software to apply the Outlook 2003 update to remove the risk of the memory leak.

Note: It has been reported that the 1.4.2607.0 version of the Outlfltr.dll file that is included with this update resolves a memory leak in the Outlfltr.dll 1.2.32 file. This behavior may impact any MAPI program that uses IMessage::SaveChange in Outlook 2003. For example, this behavior may impact archiving solutions. If you have problems running a MAPI program with Outlook 2003, please contact the manufacturer of the software package for support. In some instances, they may recommend that you install this update to resolve the problem.
