What Happens to Email Data

Data integrity remains a primary consideration throughout the conversion process. The Cigati MBOX File Converter tool retains the following elements accurately during every export:

  • Email Content: Message bodies are preserved in their original form, which includes text, HTML formatting, and embedded elements that make sure readability remains consistent after conversion.
  • Attachments: All file attachments linked to emails are retained & mapped correctly to their original messages, maintaining accessibility without requiring separate extraction steps.
  • To/CC/BCC: Recipient details across To, CC, and BCC fields are preserved precisely, that maintain an accurate record of communication threads and distribution.
  • Date & Time: Original timestamps for sent and received emails are maintained. This allows chronological order and audit trails to remain intact after conversion.
  • Folder Structure: The hierarchical arrangement of folders & subfolders is retained, that makes sure the converted output mirrors the source mailbox organization closely.
  • Email Formatting: Font styles, layout structure, & visual formatting within messages are preserved, keeping the appearance of emails consistent with the original source.
  • Metadata: Associated metadata, including headers, message IDs, and other properties, is retained to support authenticity and traceability of converted email data.

Mailbox Mapping & Migration Options

Migrating MBOX files to Microsoft 365 or Google Workspace requires accurate mailbox assignment. Cigati MBOX Converter Wizard offers flexible mapping options, letting administrators control exactly which files go to which destination accounts.

Choose Migration Mode

Before migration begins, users select how MBOX files map to target mailboxes.

  • Migrate All Files to Selected Mailbox(es) sends every selected file to the same destination accounts.
  • Map Each File to Specific Mailbox(es) lets each file be assigned individually, which suits migrations involving multiple users.
step-1

Automatic User Fetch from Admin ID

Users are fetched directly from the admin account, displaying name, user ID, mailbox type, and validation status for each one. A search bar helps locate specific users quickly, while a CSV import option is available for uploading a predefined user list instead.

step-1

Folder Mapping for Microsoft 365

Each source MBOX file can be mapped to one or more target mailboxes before migration. Users can select individual mailboxes or use Select All, with licensed and unlicensed accounts clearly marked to prevent assignment errors. A search bar and CSV import make handling larger user lists easier.

step-1

Google Workspace accounts are listed with user IDs after authentication through a JSON key, letting users choose specific destination accounts. Each MBOX file can then be matched to its corresponding Google Workspace user, with CSV import and sample templates available for bulk mapping.

step-1

Note: Whether managing a handful of accounts or a full organization, mapping options adapt to migration needs of any scale.

Convert Multiple MBOX Files Together

The MBOX Exporter Tool supports adding several MBOX files or entire folders in a single session, removing the need to process each file individually. Businesses and technicians handling large volumes of mailbox data can select multiple sources at once and run the conversion as one combined task, saving considerable time during large-scale migrations or backups.

Handling Large MBOX Files Without Data Loss

The tool is built to process large MBOX files reliably, without imposing strict size limitations that could interrupt the conversion. Large mailboxes convert intact, keeping data structure and content accurate throughout, so users working with extensive archives can proceed without concerns about file corruption or forced splitting.

Secure Authentication and Data Privacy

  • OAuth/Modern Authentication: Cloud migrations use OAuth-based sign-in, allowing secure authorization without exposing account credentials during the process.
  • Password Storage: User passwords are never stored by the tool, reducing risk and keeping account credentials fully under user control.
  • Local Processing: All mailbox conversion happens directly on your computer. Data isn't uploaded to external servers, so your emails stay under your control throughout.
  • Data Privacy: Your data is never accessed, shared, or exposed to third parties during conversion. What's on your system stays on your system.
  • GDPR Compliance: The tool is built to align with GDPR principles. It gives you full control over your data & respecting privacy requirements at every step of the migration.

FAQ

Frequently Asked Questions

Yes. The conversion process works independently of any email client. So there's no requirement to have Thunderbird or a similar MBOX-based application installed on your system.

It does. You can add several MBOX files or complete folders together & process them all within a single session, rather than converting one file at a time.

The MBOX Converter Wizard handles large files without imposing strict size caps. So data remains intact no matter how large the mailbox is.

The original folder hierarchy carries over exactly as it was, so the converted output reflects the same organization as the source mailbox.

Attachment settings give you the choice to include or leave out attachments. It depends on what your storage or output needs call for.

There's an option to skip empty folders entirely, keeping your converted output tidy and free of unnecessary blank entries.

The MBOX Converter Software relies on OAuth-based modern authentication. It enables a secure sign-in to platforms such as Microsoft 365 or Google Workspace without ever exposing your credentials.

No connection is needed for these local conversions, since PST & EML processing takes place entirely on your own system.

Data integrity is maintained throughout the process. So if something interrupts the process, you can restart without risking damage to files already converted.

Metadata, which includes headers and message identifiers, stays intact through conversion, which helps preserve accurate tracking & authenticity of your emails.

An include-items setting lets you narrow the scope to particular data types. It gives you control over exactly what gets carried into the final output.
