Convert Proofpoint Exports in a Single Pass
Native password-protected ZIP processing for Aid4Mail Enterprise
Proofpoint archives arrive as password-protected ZIPs with every account mixed together. Aid4Mail Enterprise reads them natively and reorganizes the mail into one mailbox per account in a single pass—built for Proofpoint to Microsoft 365.
What Aid4Mail Handles
Password-Protected ZIPs
Read Proofpoint’s native format directly—no manual unzip
Single-Pass Reorganization
Sort a mixed archive into per-account mailboxes in one pass
Built for Microsoft 365
One PST per user for network-upload import
Enterprise Scale
Concurrent, unattended conversion of large archives
Proofpoint Exports Arrive Mixed and Locked
A Proofpoint export is a set of password-protected ZIPs with every user’s mail mixed together. Handled by hand, you unzip everything and reprocess the archive once per account.
The Manual Approach
- ⯈ Unzip password-protected archives by hand
- ⯈ Every account’s mail mixed together
- ⯈ Reprocess the whole archive per mailbox
- ⯈ Re-sort thousands of messages manually
- ⯈ Slow and hard to scale
With Aid4Mail Enterprise
- ⯈ Reads the password-protected ZIPs natively
- ⯈ Reorganizes into one mailbox per account
- ⯈ Processes the source once, in a single pass
- ⯈ One PST per user for Microsoft 365 import
- ⯈ Concurrent, unattended processing
the mixed archive is processed once, not once per account
reorganized into per-user mailboxes by email address

Core Conversion Capabilities
Read Proofpoint’s native format, reorganize a mixed archive by account, and convert for Microsoft 365—in the Aid4Mail Enterprise edition.
Native Password-Protected ZIP Reading
Aid4Mail Enterprise reads Proofpoint’s password-protected ZIP archives directly—enter the password once, with no manual unzip.
No manual unzip
Single-Pass Reorganization
Proofpoint archives arrive with every account mixed together. The {EmailAccount} template files each message into a per-account folder in one pass over the source.
Processed once
Per-Account PST Output
Convert each reorganized folder to its own PST with a wildcard and Session > Duplicate—one PST per user, named by email address.
One PST per user
Built for Microsoft 365
Produce one PST per mailbox for Microsoft’s network upload (PST import) into Exchange Online—or migrate directly for small archives.
M365-ready
De-Journaling & Cloud Attachments
Optionally remove journaling envelopes and collect cloud attachments and their metadata during the same conversion.
Optional add-ons
Enterprise Edition
Native Proofpoint processing, single-pass reorganization, and multi-session conversion are Aid4Mail Enterprise features.

How Proofpoint Conversion Works
A four-step workflow: read the password-protected ZIPs, reorganize by account, convert per account, then migrate to Microsoft 365.
Point Aid4Mail at the ZIPs
Select the Proofpoint format, choose the folder of password-protected ZIPs, and enter the password—no manual unzip.
Native: Reads the password-protected archive format directly
Reorganize by Account
Run one session with the {EmailAccount} folder template (Target = EML) to sort the whole mixed archive into one folder per email address.
Single pass: The source data is processed only once, regardless of account count
Convert Per Account
Point a session at the reorganized folders with a trailing wildcard, set the PST target, then Session > Duplicate for one session per account.
Deterministic: One PST per mailbox, named by email address
Migrate to Microsoft 365
Upload the per-account PSTs with Microsoft’s network upload, or run all sessions concurrently and migrate directly for small archives.
Unattended: Run all works through the queue unattended, up to 16 sessions at once
One Pass, Not One Per Account
Because a Proofpoint archive is one mixed pool of mail, Aid4Mail reads it once and files every message into the right mailbox—no reprocessing per account.
Single-pass reorganization
- ✓ Proofpoint archives arrive mixed, so reorganization is always the first step
- ✓ The {EmailAccount} template sorts the whole archive in a single pass
- ✓ Refine by domain—for example, {EmailAccount:*@yourcompany.com}
- ✓ The source data is processed once, regardless of how many accounts it holds
“I tried to handle our Proofpoint archive of 3.3 million emails (940 GB of data) with cheap tools that froze and never finished after days of processing. Got in touch with Fookes Software and could not be happier with the outcome. Their Aid4Mail program was able to process all the emails and reorganized them per mailbox in less than 8 hours!”

Filter, Search, and Scale in a Single Pass
Proofpoint conversion isn’t only a format swap. In the Enterprise edition, you can search and filter the mail as it converts, and run per-account conversions in parallel.
Search and filter as you convert
- ✓ Search email with familiar operators modeled on Gmail and Microsoft syntax—plus Boolean, proximity, and wildcards
- ✓ Match patterns with regular expressions (PCRE2)—phone numbers, account numbers, or project codes
- ✓ Search inside attachment contents, including files nested within attachments—a Word document inside a ZIP
- ✓ Convert only the messages that match—filtering runs in the same workflow, with no separate tool or second pass
Run conversions in parallel
- ✓ Split output into one PST per account, then process those sessions concurrently instead of one after another
- ✓ Configure up to 16 concurrent sessions, launched together with a single Run all
- ✓ Expect a substantial speedup on capable hardware—a fast multi-core CPU, ample memory, and an SSD
- ✓ Queue more sessions than run at once; the batch advances unattended as each slot frees
Search, filtering, and concurrent processing are available in the Aid4Mail Enterprise edition. Attachment-text search covers extractable content (no OCR; encrypted or password-protected files aren’t extracted). Conversion speed depends on your hardware, the source data, and how much the filter removes.

Native Proofpoint processing, single-pass reorganization, and multi-session conversion are Aid4Mail Enterprise features. The {EmailAccount} template is available in the Enterprise and Investigator editions. For large archives, convert to PST or EML and verify the results, then upload the PSTs to Microsoft 365 with network upload or migrate directly for small archives.

Implementation Best Practices
Recommended Settings
- → Reorganize the mixed archive by account first, then convert per account
- → Enter the ZIP password (leave blank if there is none)
- → Use “Use FNV-1a signature” filenames to speed up conversion
- → Tune the number of concurrent sessions to your hardware for the convert phase (up to 16)
- → For large archives, convert and verify, then upload to Microsoft 365
Common Pitfalls to Avoid
- ✗ Don’t expect Converter or Investigator to read Proofpoint natively—it requires Enterprise
- ✗ Don’t skip reorganization—archives always arrive mixed
- ✗ Don’t leave Strict behavior on unless you’ve tested it—Proofpoint clients usually keep it off
- ✗ Don’t under-provision disk space—reorganizing decompresses the archive
- ✗ Don’t migrate huge archives directly—convert, verify, then upload
