ENVIRONMENT

  • GFI Archiver 
  • All supported environments 

SOLUTION

  1. Open the web page
  2. Navigate to: Configuration > Mailbox Folder Structure Retrieval
  3. Click on: Change Settings
  4. Ensure that the feature is configured to connect to Exchange using the correct protocol for the environment
    • EWS for Microsoft Exchange 2007 SP1 or newer or Microsoft Office 365
    • MAPI for Microsoft Exchange 2003
  5. Stop the GFI Archiver services
  6. Delete the file: ..\GFI\Archiver\Core\UMPolling\queue\MARCEMQUEUE.FDB
  7. Start the GFI Archiver services

CAUSE

The database ..\GFI\Archiver\Core\UMPolling\queue\MARCEMQUEUE.FDB is corrupt or has grown too large.
