Key Features
A complete desktop email backup software for Windows: an email backup utility that runs automated, bulk email backup from any email service. Professional features for accurate, fast and private mailbox backup, migration and archiving.
Backup All Email Services
Backup Gmail, Google Workspace, Microsoft 365, Outlook.com, Yahoo, AOL, iCloud, Zoho, Exchange, GoDaddy, cPanel webmail and 20+ named services. A universal IMAP option covers every other mailbox.
Bulk Email Backup for Multiple Accounts
Add multiple accounts and back them all up in one run. Load a CSV of addresses and app passwords for unattended batch jobs across dozens of mailboxes.
Incremental Backup Engine
The first run downloads everything. Every run after that downloads only new mail, so keeping the backup current takes minutes instead of hours.
Automatic Scheduled Email Backup
Set it once and the built-in scheduler runs continuous email backup daily, weekly or monthly. One click of setup becomes a backup habit that never skips a month.
Selective Email Backup by Folder
Folders list with checkboxes before anything downloads. Backup email folders that matter, skip Promotions and Spam and keep the archive focused.
Advanced Date Range Filter
Backup emails from a specific date range, time period or custom dates. Pull one year, one quarter or everything since the last audit.
Sender & Recipient Filter
Backup only mail from or to specific addresses. Pull one client's complete correspondence into its own archive without touching the rest.
Subject Line Search Filter
Filter the backup by subject keywords. Project names, case numbers and invoice references become precise backup criteria.
Complete Attachment Preservation
Every attachment comes down with its message: documents, photos, spreadsheets, zipped archives and inline images, all with original filenames.
Folder Hierarchy Retention
Your folder tree survives the trip. Inbox, Sent, Drafts and every nested custom folder appear in the backup exactly where you keep them.
Email Header Preservation
From, To, CC, BCC, subjects, dates, Message-IDs and the full routing trail stay intact, which is what makes a backup usable as a record.
Custom File Naming Options
Name backup files by date, subject, sender or combinations. PDF and EML archives arrive organized the way your filing system expects.
Built-in Email Preview
Browse folders and read full messages before the backup runs, so you always know exactly what a job will download.
Split PST for Large Mailboxes
Choose a size and the software splits PST output automatically. A 60 GB mailbox arrives as clean smaller files Outlook opens without complaint.
Duplicate Email Detection
Backup email with no duplicates. Repeat runs and overlapping folders never bloat the archive with second copies of the same message.
Pause, Resume and Retry
Long backups survive real life. Pause a job and resume it later. Automatic retry handles the connection drops that come with large downloads.
Backup Log and Verified Counts
Every job ends with a report: messages found, messages saved, attachments extracted. You know the backup is complete because the numbers say so.
Backup and Restore in One Tool
Email backup and restore software in the full sense: cloud destinations move mail into another account and the reverse run restores it later.
Everything Preserved During Conversion
Simple Process
No technical knowledge required. Sign in to your email service, pick folders and format and the backup runs on its own.
Sign In to Your Service
Pick your provider from the list or choose IMAP for any other mailbox. Gmail, Microsoft 365 and Outlook.com sign in through their own official login windows, so no password is stored. Other services use your password or an app password.
Choose Folders and Format
Tick the folders you want, apply date, sender or subject filters and pick an output format such as PST, PDF, MBOX or EML.
Start Backup
Click "Start Backup" and watch live progress. When it finishes, your emails sit in the folder you chose with a full log beside them.

Why You Need This
Why Backup Your Email?
Account Lockouts and Hacks
A hijacked account, a ransomware incident or a failed recovery process can cut you off from years of mail in an afternoon. A local backup means losing the account never means losing the email.
✓ Your copy survives any lockout
Accidental Deletion
Trash folders empty themselves on a timer, usually after 30 days. Once the provider purges a message, no support ticket brings it back. Backup email before deleting anything and your own copy has no timer.
✓ Your copy has no expiry date
Leaving a Job or School
Work and university mailboxes close when you leave, often with little notice. Backup email before closing the account and a deactivated mailbox becomes an archive you keep for life.
✓ Your mail outlives the account
Provider Shutdowns and Changes
ISP mail services close, free tiers shrink and storage policies change. Email you control on your own drive is immune to another company's roadmap.
✓ Independent of any provider
Compliance and Legal Holds
Businesses face retention rules under GDPR, HIPAA and tax law. PST and PDF backups create reviewable, portable records that satisfy auditors without a live account.
✓ Audit-ready email archiving
Offline and Travel Access
A local archive opens on a plane, in a dead zone or a decade from now. PDF backups stay readable on any device without any email software at all.
✓ Your mail, readable anywhere
Export Formats
Save email backups as PST, PDF, MBOX, EML and more. As email archiving software it writes records that outlive any account. Save emails to an external hard drive, USB flash drive, NAS share or any folder Windows can reach. Choose the right output for Outlook, long-term archives, legal review or spreadsheets.
Forensic and eDiscovery
Univik Email Backup Software keeps email in its original form during backup. Legal teams, auditors and investigators get records that stand up to review, whether you backup email for compliance, legal discovery or record keeping.
Keeps Email Details Intact
The backup is a faithful copy: true send and receive timestamps, untouched routing headers and original message IDs, exactly as the server holds them.
Saves Folders and Attachments
The downloaded archive mirrors the live mailbox: every folder in its place, every attachment inside its message, nothing reorganized.
Export to PDF for Review
PDF backups drop straight into case files and audit binders. EML and MBOX copies load into review platforms and forensic suites when deeper analysis is needed.
Records Anyone Can Verify
The end-of-job report lists exactly what was found and what was saved, folder by folder, so a reviewer can check the backup against the mailbox.
Built for Long Retention Jobs
Decade-old mailboxes with six figures of messages download folder by folder to completion. Retention projects finish with nothing dropped along the way.
Runs on Your Own Machine
Backups run on your own Windows machine. Sensitive correspondence moves from your mail server to your drive with no third party in between.
Professional Use Cases
A professional email backup tool for IT teams and an email backup solution for business owners, legal teams and everyday account holders alike.
IT Administrators
Backup departing employee mailboxes to PST before seats close, shared mailboxes included. CSV batch mode works through offboarding lists unattended.
IT Service Providers and MSPs
Mailbox backup software for people who manage other people's mail. Batch backup across dozens of client accounts and custom domains from one tool.
Legal Professionals
Archive client correspondence to searchable PDF at each engagement close. Headers, dates and attachments preserved for discovery and audits.
Business Users
Backup business email on custom domains before hosting changes, domain transfers or provider switches. Retention obligations met with portable files.
Personal Users
Backup email before deleting an account or leaving a provider. Years of family correspondence, receipts and records saved to a drive at home.
Families Handling an Estate
Preserve a relative's mailbox completely before the provider deactivates it, keeping the photos, letters and records a family would otherwise lose.
Customer Reviews
Trusted by Thousands Worldwide
We back up every leaver's Microsoft 365 mailbox to PST before the seat is released. The CSV batch mode and the count report at the end are exactly what an IT team needs for sign-off.
I had six accounts across Gmail, Yahoo and my old ISP. One evening with this tool and all of them now live on my external drive as PDF and MBOX. The monthly incremental run takes about ten minutes.
My father passed away and his provider gave us 60 days before closing the account. This software downloaded 14 years of his email in an afternoon. What that archive means to us is hard to put into words.

Frequently Asked Questions
Email backup software is a program that signs in to your email account the same way your phone does, downloads every message to your computer and saves the mail in formats you choose, such as PST, PDF, MBOX or EML.
The result is a copy of your mailbox that you own outright: it opens without internet, survives account lockouts and stays readable regardless of what happens to the provider. Univik Email Backup Software does this for any email service with folders, attachments and headers preserved.
All of them, in practice. Named presets cover:
For everything else there is a universal IMAP option: enter your server address and credentials and the software backs up any IMAP-enabled mailbox. ProtonMail connects through ProtonMail Bridge.
Yes. Providers with two-factor authentication issue app passwords exactly for this situation: a separate 16-character password that grants mail access without your main password or codes. Generate one in your account security settings, use it in the software and the backup proceeds normally. The software includes short guides for creating app passwords on Yahoo, iCloud, Zoho and other providers. Gmail, Microsoft 365 and Outlook.com skip app passwords entirely: they sign in through their own official login windows, with no password stored in the software.
Yes, by architecture rather than by promise. The application runs on your Windows computer and connects directly to your mail server over an encrypted connection. Your password goes to your provider and nowhere else. Your messages travel from the server straight to your drive. Nothing routes through Univik servers because there is no Univik server in the path.
The first backup downloads your whole mailbox. Incremental backup means every later run downloads only messages that arrived since the previous run. A mailbox that took four hours the first time updates in minutes afterward. This is what makes a monthly backup habit realistic instead of a chore you abandon.
Yes. The built-in scheduler runs backups daily, weekly or monthly without you at the keyboard. Each scheduled run is incremental, so it downloads only new mail. Set it once against your accounts and a hard drive or NAS destination and the copy stays current on its own. Scheduling is included in the Business license.
It depends on the job:
You can back up the same account to several formats in separate runs.
Yes. Add accounts one by one inside the software or load a CSV file of addresses and app passwords for bulk email backup. Each account backs up to its own folder with its own log. IT teams use the CSV mode to work through departing-employee mailboxes and client account lists unattended, shared mailboxes included.
Yes. The software is built for mailboxes in the tens of gigabytes with hundreds of thousands of messages. Downloads run folder by folder with automatic retry on connection drops, pause and resume for jobs that span days and duplicate detection so repeat runs never bloat the archive. The trial behaves identically, so you can test your largest mailbox before buying.
Yes. This is email backup and restore software in the full sense: the cloud destination options send mail directly from the source account into another account. Running the migration in reverse restores it later. Folder structure maps across automatically. For a full account-to-account move with delta sync and cutover support, the dedicated Univik Email Migration Software is built for exactly that job. Many users run both: a migration to the new account and a local backup for the drawer.
The honest answer: the one that backs up all your accounts, keeps itself current and never sees your data. Judge any candidate on five points:
Univik Email Backup Software was built around exactly those five, which is why the free trial exists: test the claim on your own mailbox.
Backup protects against loss: a current copy of your mailbox you can restore from. Archiving preserves records: a permanent, readable, often searchable store of mail kept for reference or compliance, independent of any live account.
This software does both jobs. Incremental runs to PST or MBOX keep a restorable backup, while PDF and EML output works as email archiving software, producing records that stay readable for decades without any email program.
Windows 11, 10, 8.1, 8 and 7 (32 and 64-bit) plus Windows Server 2022, 2019, 2016 and 2012. 4 GB RAM minimum with 8 GB recommended for large mailboxes, 250 MB disk space for the software plus room for your mail archive. The application is s .NET Framework 4.8 or higher is required and comes preinstalled on Windows 10 and 11. tandalone: Microsoft Outlook is not required, even for PST output. Internet is needed during backup to reach your mail server; finished backups open offline.
The free trial is the full software with one limit: it backs up the first 25 emails per folder. Every feature works, including filters, all formats and multi-account mode, so you can verify complete results on your own mailbox before spending anything. A one-time license removes the limit, with no subscription and no monthly fee.
