How To Backup All Emails In Outlook
Introduction
In Australia’s fast-moving business environment, Microsoft Outlook remains the backbone of corporate communication. Whether your company runs on Office 365, Microsoft 365, or standalone versions like Outlook 2019 or Outlook 2024, safeguarding your Outlook emails is essential. Backing up your email data protects your business from data loss, cyber threats like ransomware, and compliance issues under Australian regulations.
This detailed guide from Enabla Technology walks you through every essential aspect of Outlook backup — from PST files and OST files to cloud backup, third-party backup software, and Exchange Online strategies. We’ll also explore how to restore your emails and implement a long-term backup strategy that ensures business continuity.
Understanding Outlook Email Backup
What Does It Mean to Backup Microsoft Outlook Emails?
Backing up Microsoft Outlook emails involves creating a secure backup file of your Outlook Data Files (.pst) or Outlook Data Files (.ost). These files contain email messages, contacts, calendar info, tasks, and notes. The backup is typically stored locally on your hard drive, in the AppData folder, or externally on a Flash Drive/USB or cloud-based system.
- PST file (Personal Folder File): Used for POP/IMAP or archived Outlook Accounts.
- OST file (Offline Outlook Data File): Used for Exchange accounts, enabling Offline Access via Cached Exchange Mode.
Why Backup Outlook Emails Regularly?
Businesses that rely on Outlook or Office 365 mailboxes must have a structured backup and recovery plan. Backups ensure:
- Protection from Data Loss: Accidental deletions, hardware failures, or data corruption.
- Cybersecurity Features: Safeguard against ransomware protection and other security threats.
- Email Synchronization: Maintain continuity between devices and email accounts.
- Compliance: Fulfil Australian retention and privacy requirements with secure data retention.
- Migration Ease: When changing email hosts, managed WordPress, or VPS packages, backups make transitions seamless.
Methods to Backup Outlook Emails
1. Export Outlook Emails Using the Import and Export Wizard
Microsoft Outlook offers a built-in Import/Export wizard that allows you to export your emails into a PST file (Outlook Data File) or CSV file for spreadsheets such as Microsoft Excel.
Step-by-Step: Export Using the Import and Export Wizard (Windows)
- OpenMicrosoft Outlook and Sign in to your Outlook Account.
- Go to File > Open & Export > Import/Export.
- Choose Export to a file and click Next.
- Select Outlook Data File (.pst) and click Next.
- Pick the mail folders or root folder you want to back up.
- Choose a file path on your hard drive or Flash Drive/USB for the backup.
- Complete the export process by clicking Finish.
For Mac Users:
- Go to File > Export.

- Select message folders and start the export.
Note: The progress box will show the export status. When complete, verify the backup file in the selected folder.
| Step | Windows | Mac |
|---|---|---|
| Export Tool | Import/Export Wizard | File > Export |
| Output Type | PST File | OLM File |
| Format | Outlook Data File (.pst) | Outlook for Mac Data File (.olm) |
What Gets Backed Up: Emails, attachments, calendar info, contacts, and message rules.
2. Configure AutoArchive Settings
The AutoArchive settings in Microsoft Outlook automatically move older emails into a PST file for long-term storage.
How to Set Up AutoArchive:
- Go to File > Options > Advanced.
- Under AutoArchive, click AutoArchive Settings.
- Set the frequency, location, and retention time.
- Select the Outlook Data File (.pst) location.
This helps manage email storage while ensuring compliance with retention policies.
3. Manual Drag-and-Drop Backup
For small-scale tasks:
- Select emails or folders in Outlook.
- Drag and drop them into a Windows or Mac folder.
Pros: Simple and free.
Cons: Limited control, manual process, and increased risk of data corruption.
4. Backing Up Outlook Emails to Gmail or Other Email Services
You can back up emails by transferring them to another email account (like Gmail):
- Add your Gmail account via File > Add Account.
- With both accounts visible, select your target message folders.
- Use Move > Copy to Folder to copy Outlook emails to Gmail.
This ensures your email messages are accessible even if your local Outlook Data File becomes inaccessible.
5. Using Third-Party Backup Solutions
Automated Third-Party Backup Solutions like Acronis True Image, Spanning Backup, MSP360 Backup, or other API-enabled backup services simplify the process.
Key Benefits:
- Scheduled and automated backups.
- Integration with Exchange Online and Microsoft Exchange Server.
- Cloud and local storage options.
- Ransomware protection and cybersecurity features.
Setup Steps:
- Create a Backup Account on your chosen service.
- Connect your Outlook Account or Office 365 mailbox.

Comparison Table:
| Method | Manual Backup | Third-Party Tools |
|---|---|---|
| Automation | No | Yes |
| Cost | Free | Subscription |
| Security | Basic | Advanced (encryption, API-based) |
| Cloud Backup | Optional | Built-in |

Advanced Outlook Backup Strategies
Automated vs Manual Backups
Automated Backups:
- Scheduled, reliable, and ideal for businesses using Exchange Mode or Cached Exchange Mode.
- Reduces manual errors and ensures version control.
Manual Backups:
- Ideal for ad-hoc use or individual users.
- Recommended when exporting smaller Data Files or personal archives.
Enabla Technology Recommendation:
Combine both for robust protection — a hybrid backup strategy offering cloud and local redundancy.
Cloud vs Local Storage
| Factor | Cloud Backup | Local Backup |
|---|---|---|
| Accessibility | Remote, 24/7 | On-site only |
| Security | Encryption, two-step authentication | Physical access risk |
| File Type | PST/OST mirror | PST/OST local |
| Cost | Subscription | Hardware only |
Best Practice: Store backups both locally (in the AppData folder or hard drive) and off-site (in a cloud or managed hosting environment).
