IMAP Backup Tool

No. Prism operates on a completely standalone 64-bit binary engine. It creates native Microsoft Outlook Unicode PST files directly on disk without requiring Outlook to be installed, running, or configured with Outlook profiles.

You do not need to restart from scratch. Prism features an embedded SQLite ACID checkpoint database that records every processed message UID in real time. When your connection restores, click 'Resume Migration' in the Step 1 Resume Center. The engine queries the local checkpoint table and resumes downloading from the exact message where it stopped, saving bandwidth and preventing duplicate files.

For accounts protected with 2-Factor Authentication like Yahoo Mail, Zoho, or Gmail, you must generate a dedicated 16-character App Password in your account security settings. Under Step 1, select your provider preset (Yahoo, Zoho, Gmail). Prism built-in ImapAuthHelper automatically connects over Port 993 SSL and sanitizes any spaces or hyphens accidentally copied, establishing an immediate authenticated TLS pipeline without socket drops.

Yes. In Step 1, select 'Enterprise CSV Batch'. Upload a standard CSV file with columns formatted as host, port, ssl, email, and password. The engine validates each connection, populates the batch queue, and processes mailboxes concurrently across isolated worker threads.

Port 993 is the standard IANA port for implicit IMAP over SSL/TLS, where encryption is negotiated immediately upon TCP socket connection. Port 143 is the traditional IMAP port that connects in plain text and then upgrades to secure encryption using the STARTTLS command. Prism supports both modes, as well as custom web host ports like 2096.

Yes. When exporting to PDF, you can configure sequential Bates numbering (such as CORP-CASE-000100), adjust header and footer positioning, and embed email attachments inside the PDF output.

Yes. Under Step 4 (Cloud Migrations), select 'Office 365' or 'Gmail'. Prism authenticates directly with Microsoft Graph API or Google OAuth 2.0 PKCE, streaming email messages directly from your source IMAP host into cloud mailboxes without writing intermediate files to workstation storage.

Prism includes a cryptographic deduplication engine. Under Step 3 (Deduplication), choose the fields to compare: Subject, Sender, Recipients, Sent Date, Message Body, Message-ID Header, or Attachment Names. You can also select pre-built presets ('Strict', 'Metadata', 'Content Only') to eliminate duplicated emails generated by aborted syncs.
