Every Byte Matters.
Stop Converting Files.
Just Move Your Emails to the Cloud.
DT PST Migrator pushes your PST data directly into Office 365, Google Workspace, Exchange Zoho Mail, or any IMAP server.
- ✗ No intermediate file format.
- ✗ No upload to our servers.
- ✗ No data left behind.
Wait — What's the Difference Between Converting and Migrating?
Good question. A lot of people don't know there's a difference until they're halfway through the wrong tool.
PST Converter = Takes your PST file and creates a new file in a different format (MBOX, PDF, EML, etc.) on your computer. You still have to import that file somewhere yourself.
PST Migrator= Takes your PST file and pushes the emails directly into your cloud inbox — Office 365, Gmail, Exchange. No intermediate file. No manual import step. It's done when it's done.
Which one do you need?
If you're moving email to the cloud and you want it to just show up in your inbox — DT PST Migrator is what you need.
Which Cloud Are You Moving To?
DT PST Migrator connects directly to your cloud environment via OAuth 2.0 and pushes your emails straight in. No file export. No manual import. No third step.
Office 365 / Microsoft 365
The most common use case. Moving company PST archives to Microsoft 365 mailboxes — individual users or bulk migration across hundreds of accounts with user mapping.
Google Workspace / Gmail
Switching from Outlook to Google? DT PST Migrator lands your PST emails directly in Gmail — folders preserved, attachments intact, nothing lost.
Exchange Server
On-premise or hosted Exchange. Migrate PST data directly into user mailboxes with impersonation support — no individual passwords required.
Zoho Mail
Moving to Zoho? Direct IMAP-based push migration — full folder structure, complete metadata.
Any IMAP Server
Hostinger, Namecheap, cPanel mail, or any standard IMAP server. If it supports IMAP, DT PST Migrator can push to it.
Why Are PST Files on Local Machines Such a Problem?
PST files were fine when everyone worked at the same desk every day.
Local PST Storage Risk
A PST file sitting on one person's laptop means: if the laptop dies, the emails die with it. If the person leaves, IT scrambles to recover the data. If an auditor asks for emails, nobody can find them quickly. If the file grows too large, Outlook starts throwing errors.
Cloud Retention Solution
Migrating PST data to Office 365 or Google Workspace solves all of this at once. Emails become searchable, backed up, accessible from any device, and covered by your cloud retention policies — without any extra work.
DT PST Migrator gets that data in. Clean. Complete. Audited.
Five Steps. Then It's in the Cloud.
No manual import. No data left behind.
Install on Your Windows Machine
Download and install DT PST Migrator. Works on Windows 10, 11, and Windows Server. No Outlook installation needed.
Add Your PST Files
Load a single PST file or an entire folder of PST files for batch migration. No file size limit — tested on 100GB+ files.
Connect to Your Cloud Destination
Sign in to Office 365, Google Workspace, Exchange, or IMAP via secure OAuth 2.0. Your login credentials are never stored by the tool or by us.
Map Users (For Bulk Migrations)
Migrating multiple users? Import a CSV file to map each PST to the right cloud mailbox — no manual matching per account.
Migrate and Monitor
Start the migration. Watch live progress. If the network drops — it pauses and resumes automatically from exactly where it stopped. Download the full audit report when done.
Your Emails Go From Your Machine Directly to Your Cloud.
We're Not in the Middle.
DT PST Migrator creates a direct, encrypted connection between your local PST file and your cloud mailbox. Your data never passes through our servers. Not for authentication. Not for processing. Not for logging.
We authenticate using OAuth 2.0 — the same secure standard your bank uses. No passwords stored. No sessions logged. No one at Data TB can see what's in your mailbox. The migration path is: Your machine → Your cloud. Two points. No detours.
OAuth 2.0 Authentication
Modern, token-based login. No passwords stored anywhere.
Zero Server Touch
Your emails never route through Data TB infrastructure.
Auto-Resume on Drop
Connection lost mid-migration? Picks up exactly where it stopped. No duplicate emails created.
Full Audit Report
Every email migrated, skipped, or flagged — logged with timestamps. Export as CSV for compliance records.
The Cases That Make Other Tools Fail
Built for the hard migrations nobody else handles.
Migrating 500 users at once?
Use bulk migration with CSV user mapping. Load all PST files, map each to the right mailbox, run it overnight. Full audit log in the morning.
PST file over 100GB?
No size limit. Multi-threaded engine processes terabyte-scale migrations without crashing or throttling itself.
Migration ran before — don't want duplicates?
Delta sync detects what's already in the destination mailbox and skips it. Run the migration again safely — only new emails get pushed.
Need to skip certain folders?
Junk, Deleted Items, or any folder you don't want migrated — exclude it before you start. Only migrate what matters.
Running migration during business hours?
Built-in bandwidth throttling lets you control how much network the tool uses — so your team's connection stays fast while it runs.
Don't have individual user passwords?
Use impersonation with global admin credentials for Office 365 and Exchange — migrate into user mailboxes without asking each person for their login.

Real Questions Before You Run a Migration
Straight answers. No fluff.
QDo I need Microsoft Outlook installed to use this?
ANo. DT PST Migrator reads PST files using its own built-in engine — completely independent of Outlook.
QDo I need admin credentials for Office 365?
AFor single-user migrations, your own credentials are enough. For bulk migrations into multiple mailboxes, yes — you'll need global admin access to use impersonation, which lets the tool migrate into user mailboxes without their individual passwords.
QWhat happens if my internet drops mid-migration?
ANothing is lost. Auto-resume kicks in and the tool picks up exactly where it stopped — no duplicate emails, no items skipped.
QWill emails already in the cloud get duplicated?
ANo. Delta sync checks what's already in the destination mailbox before pushing anything. Only emails that aren't already there get migrated.
QCan I migrate multiple PST files to different users at once?
AYes. Use CSV bulk mapping — list each PST and its corresponding mailbox, import the file, and the tool handles all of them in one session.
QCan I exclude certain folders from migrating?
AYes. Preview the folder structure before migration starts and deselect anything you don't want — Junk, Deleted Items, specific subfolders.
QIs there a file size limit?
ANone. The tool is tested on PST files over 100GB. Terabyte-scale migrations complete without issues.
QDoes my email data pass through Data TB's servers?
ANever. Your migration goes directly from your machine to your cloud mailbox. We don't receive, route, or see any of your email content.
