Stellar Repair for Exchange supports Parallel Processing. The Exchange recovery tool can process and save up to 4 mailboxes together to PST, Office 365, or live Exchange server. Parallel Processing helps reduce the time required to scan, repair, and save mailboxes from a damaged or corrupt Exchange database significantly.


However, Parallel Processing is hardware dependent. Thus, to utilize the Parallel Processing feature for faster mailbox recovery, the software requires a 64-bit system with at least 4 GB free RAM.

To ensure best performance and parallel processing, you must install and use Exchange recovery tool on a system with following specifications:

  1. Processor: Intel compatible x64
  2. Operating System: Windows 10, Windows 8.1, Windows 8, Windows 7, Windows Server 2016, Windows Server 2012, Windows Server 2008
  3. Memory: 8 GB (recommended)
  4. Hard Disk: 250 MB of Free Space
  5. MS Outlook: 64-bit Outlook 2019, Outlook 2016, Outlook 2013, Outlook 2010, or Outlook 2007
