Problem

eDiscovery or FTK Central email collection shows a hit count, but then later goes to "Failed" status.

System Log shows the following error:

Failed to add emails to PST. Failed to create instance of Redemption COM type: 'AccessDataRedemption.RDOSession'. [1]

 

Resolution

eDiscovery

  1. Confirm you've installed Outlook 2016 32-bit Professional Plus on the collections Work Manager machine.
  2. Open a command prompt.
  3. Change your current directory to the Work Manager installation folder (typically "[drive]:\Program Files\AccessData\eDiscovery\Work Manager")
  4. Issue the following command:
    regsvr32 AccessDataRedemption.dll
  5. Try your collection again.

FTK Central

  1. Confirm you've installed Outlook 2016 32-bit Professional Plus on the FTK Central server.
  2. Open a command prompt.
  3. Change your current directory to the FTK Central installation folder (typically "[drive]:\Program Files\AccessData\Forensic Tools\\bin")
  4. Issue the following command:
    regsvr32 AccessDataRedemption.dll
  5. Try your collection again.

 

Cause

PSTBuilder relies on a locally installed instance of Microsoft Outlook 32-bit. When AD eDiscovery tries to call PSTBuilder to build the collected emails into a PST file, it crashes because the Work Manager component cannot talk to the Outlook 32 bit DLLs required for PST generation.
