Failed to add emails to PST. Failed to create instance of Redemption COM type

Problem

AD eDiscovery Exchange or Office 365 email collection shows a hit count, but then later goes to "Failed" status.

System Log shows the following error:

Resolution

1. Confirm you've installed one of the following versions of Outlook on the collections Work Manager machine:
   Outlook 2007 32-bit Standard or Professional
   Outlook 2010 32-bit Standard or Professional
   Outlook 2013 32-bit Professional Plus
   Outlook 2016 32-bit Professional Plus
   
   
2. Open a command prompt.
3. Change your current directory to the Work Manager folder (ie. cd C:\Program Files\AccessData\eDiscovery\Work Manager)
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.
