Chandel Amit — Fri, 10 Jul 2026 12:44:43 +0000

Do you want to convert OST to PDF for sharing Outlook emails, archiving important conversations, or keeping legal records? You're not alone. Many Outlook users need to save their emails in PDF format because it is universally accepted, secure, and easy to access across different devices.

However, Outlook doesn't provide a direct option to convert OST files to PDF with attachments in bulk. While there are manual techniques available, they can be time-consuming and may not preserve attachments or folder hierarchy. In this guide, we'll explain both the manual and automated approaches so you can choose the one that best fits your needs.

Why Convert OST to PDF?

There are several practical reasons why users prefer PDF over OST files.

1. Easy Sharing
PDF files can be sent through email, cloud storage, USB drives, or messaging platforms without requiring Microsoft Outlook.
2. Universal Compatibility
PDF documents can be opened on Windows, macOS, Linux, Android, and iOS using almost any PDF reader.
3. Better Security
PDF files support password protection, encryption, and digital signatures, making them suitable for confidential communication.
4. Long-Term Archiving
Organizations often archive important emails in PDF format for legal, compliance, or documentation purposes.
5. Print-Friendly Format
PDF preserves the formatting of emails, making it ideal for printing official records.

Manual Method to Convert OST to PDF

If you only need to save a few emails, Outlook's built-in features can help.

Follow these steps carefully.

Launch Outlook and open the mailbox containing the desired email.
Double-click the email you want to convert.
Click:File → Save As
Choose HTML as the file format and save it.
Open the saved HTML file using Microsoft Word.
Go to:File → Save As
Select PDF (*.pdf) as the output format.
Click Save.
Your Outlook email has now been converted into a PDF document.

Alternative Manual Method (Print to PDF)

Modern versions of Outlook provide another option.

Open Outlook.
Open the email.
Click File → Print.
Select Microsoft Print to PDF.
Click Print.
Choose the destination folder.
Save the PDF. This method is easier than converting through HTML.

Limitations of the Manual Method

Although the manual method is free, it comes with several drawbacks.

Converts one email at a time
Cannot batch convert OST files
Attachments are not included inside the PDF
Folder hierarchy is not preserved
Time-consuming for large mailboxes
Risk of missing emails during manual selection
Not suitable for enterprise users

If your OST file contains thousands of emails, manual conversion quickly becomes impractical.

If converting multiple mailboxes, organize them beforehand.
Use filters to export only the required emails.

Conclusion

Converting Outlook OST files to PDF is useful for email archiving, document sharing, legal compliance, and long-term storage.

However, when dealing with large mailboxes, multiple folders, or attachments, the manual process becomes slow and restrictive.
An automated OST to PDF Converter simplifies the entire process by supporting batch conversion, preserving folder hierarchy, maintaining email formatting, and reducing the chances of data loss. Choose the method that best matches your requirements and the size of your Outlook mailbox.

How to Migrate Office 365 to IMAP: Complete Guide for Businesses and Individuals

Chandel Amit — Thu, 11 Jun 2026 12:56:19 +0000

Businesses and professionals often switch email platforms to meet changing communication requirements. While Microsoft 365 is one of the most popular cloud-based email services, some users prefer IMAP-supported email servers due to flexibility or organizational policies. As a result, many users look for reliable ways to migrate Office 365 to IMAP without losing important mailbox data. Whether you're moving to a private mail server, a hosting provider, or another IMAP-enabled email service. This blog explains the available migration methods, common challenges, and best practices for transferring Office 365 mailbox data to an IMAP account.

What Is IMAP and Why Do Users Choose It?

Internet Message Access Protocol (IMAP) is a standard email protocol that allows users to access and manage emails directly from the mail server. Unlike POP3, IMAP synchronizes mailbox data across multiple devices, which makes it a preferred option for businesses and remote teams. Organizations may decide to migrate from Microsoft 365 to an IMAP server for several reasons:

Reducing email hosting costs
Moving to a self-hosted mail server
Switching to another email provider
Centralizing mailbox management
Meeting specific compliance requirements
Simplifying email infrastructure

Why Migrate Microsoft 365 to IMAP?

Microsoft 365 provides advanced collaboration and productivity features, but not every organization requires the full Microsoft ecosystem. Some businesses only need email services and prefer a dedicated IMAP-based solution.
When organizations Migrate Microsoft 365 to IMAP, they gain greater flexibility in choosing hosting providers and managing email services according to their requirements.
Additionally, IMAP servers are supported by numerous email clients, including Thunderbird, Apple Mail, Outlook, eM Client, and many webmail platforms.

Common Challenges During Office 365 to IMAP Migration

Although the migration process sounds straightforward, users often encounter several technical challenges.

Large Mailbox Size: Migrating mailboxes containing several gigabytes of data can increase migration time and create synchronization issues.
Folder Mapping Issues: Different email platforms use different folder structures. Proper folder mapping is necessary to preserve mailbox organization.
Authentication Requirements: Microsoft 365 uses modern authentication mechanisms that may require additional configuration before migration.
Data Integrity Concerns: Organizations must ensure that emails, attachments, metadata, and folder hierarchy remain intact throughout the migration process.
Network Interruptions: Large-scale migrations may be affected by unstable internet connections or server interruptions.

Manual Method to Export Office 365 Emails to IMAP

Users can manually transfer mailbox data by configuring both Office 365 and IMAP accounts in a desktop email client such as Microsoft Outlook.

Firstly, add your Office 365 account to Outlook.
Configure the destination IMAP account.
Allow both mailboxes to synchronize completely.
Create folders in the IMAP account if necessary.
Drag and drop emails from Office 365 folders to IMAP folders.
Wait for synchronization to complete.

Limitations of the Manual Method

Time-consuming for large mailboxes.
Requires continuous monitoring.
Risk of accidental data omission.
Not suitable for bulk migration.
Folder hierarchy may not always remain intact.
Manual verification is required after migration.

Professional Solution to Migrate Office 365 to IMAP

For a quick and hassle-free migration, users can use the DRS Softech Microsoft 365 Backup Tool. The software allows users to migrate Office 365 to IMAP directly without manually configuring multiple email clients or transferring data folder by folder.

The tool securely migrates emails, attachments, contacts, and calendars while preserving the original folder hierarchy and mailbox structure. It also supports bulk mailbox migration, making it suitable for both individual users and organizations.
Apart from IMAP migration, the software offers multiple backup and export options.

Users who need email archives for compliance or documentation purposes can also Export Office 365 Emails to PDF and other popular file formats. With its user-friendly interface and advanced filtering options, the tool helps simplify complex Microsoft 365 migration projects.

Benefits of Using an Automated Migration Tool

Bulk Mailbox Migration: Organizations can migrate multiple Office 365 mailboxes simultaneously.
Preserves Folder Hierarchy: The original mailbox structure remains intact after migration.
Advanced Filtering Options: Users can migrate specific folders or selected date ranges instead of transferring entire mailboxes.
Secure Data Transfer: Modern migration tools use secure authentication methods to protect mailbox credentials and data during migration.
Reduced Administrative Effort: Automation minimizes manual intervention and simplifies large-scale migration projects.

Best Practices Before Migration

Always create a backup before starting any migration project.
Confirm server addresses, ports, and authentication requirements before initiating migration.
Review mailbox sizes to estimate migration duration and resource requirements.
Testing with a small mailbox helps identify potential issues before migrating all users.
After migration, verify emails, attachments, folders, and mailbox counts to ensure data integrity.

Conclusion

The decision to migrate Office 365 to IMAP is often driven by business requirements, hosting preferences, or cost considerations. While manual methods can be useful for small migrations, they become increasingly difficult to manage as mailbox sizes and user counts grow. For large email migration, use the professional tool.

EML Attachments Not Opening? Here’s How to Fix the Issue Easily in 2026

Chandel Amit — Thu, 21 May 2026 04:58:58 +0000

For personal use and work email, emails are an essential way of communicating. A common method used to keep individual email messages in storage is through the use of EML (Email) files; however, many people find that when they try to open the EML attachments to their emails, they do not work as they should. Some examples of issues encountered include being unable to open the attached file, the file not loading, and getting an improper format warning for the attached file. This type of issue is usually caused by file corruption, an improper file association, and/or a compatibility issue, or the email header has become corrupted.
In this informative guide you will find out why you are having problems opening your EML attachments and how you can quickly resolve those problems.

Why Are EML Attachments Not Opening?

There are several reasons why attachments inside EML files may stop working. Some common causes include:

Incorrect file association settings
Large attachment size
Antivirus restrictions
Incomplete email download
MIME header corruption

Identifying the actual cause is important before applying any solution.

How to Convert OST to MSG? A Proven Guide and Tool Overview

Chandel Amit — Wed, 02 Jul 2025 09:36:58 +0000

Converting Outlook’s OST (Offline Storage Table) files into individual MSG (Outlook Message) files is a common requirement, whether for email archiving, legal compliance, or streamlined data sharing. While you can drag-and-drop messages manually, this method is time-consuming, error-prone, and impractical for large mailboxes. Thankfully, advanced solutions like the MailConverterTools OST File Converter offers an automated, reliable, and secure alternative.

In this article, we’ll explore:

Why converting OST to MSG matters
Manual vs. automated methods
A walkthrough of a trusted OST File Converter
Key features that matter
Best practices for seamless migration

Why Convert OST Files to MSG?

Independent email access
MSG files are stand-alone—it’s easy to locate, forward, or store individual messages.
Lightweight and portable
Smaller file sizes allow easier sharing and quicker transfers across systems.
Searchable and archivable

MSG supports full headers and metadata, ideal for compliance and legal referencing.
Selective exports
Extract only the required emails instead of exporting the entire mailbox.
Cross-platform support
Unlike OST, which is tied to a specific Outlook profile, MSG can be used more flexibly.

How to Export OST to MSG Files?

Converting OST files to MSG format can be done using either manual methods or a dedicated OST file converter tool. The method you choose depends on how many emails you need to convert and whether your OST file is accessible through Outlook.
For small conversions, Outlook’s built-in features can help. But for large-scale exports or corrupted OST files, a professional tool is the safest and fastest option.

Let’s take a look at both options.

Manual Method to Convert OST File into MSG

If your Outlook is properly configured and the OST file is accessible, you can manually export emails to MSG format using a simple drag-and-drop method:

Open Microsoft Outlook and make sure your OST file is loaded.
Navigate to the folder (like Inbox or Sent Items) containing the email you want to export.
Select the email, then drag it onto your desktop or a folder in File Explorer.
It will be saved automatically as a .msg file.

Limitations of Manual Method:

Only works if Outlook is working with the OST file.
Cannot convert emails in bulk—you have to drag each email one by one.
Does not work if the OST file is orphaned or corrupt.
Not suitable for businesses or users who want to convert thousands of emails.

Why Use the OST File Converter?

If you’re handling hundreds or thousands of emails—or need to recover from an inaccessible OST file—OST File Converter simplifies the process. It not only converts OST to MSG but also offers the option to convert OST to PST, EML, CSV, HTML, PNG, MBOX, and MSG for complete mailbox recovery and backup purposes.

Step-by-Step: Using the Tool

Launch OST File Converter on your system.
Browse and add OST files (even corrupt or orphaned ones).
Preview email content—including attachment and metadata.
Select MSG as your output format.
Apply filters (date range, subject line, sender).
Choose a destination and begin export. Within minutes, your OST data is transformed into neatly organized MSG files.

Key Features of OST File Converter

Batch Conversion – Convert multiples OST file to MSG or other formats in one go.
Corruption Support – Works even if the OST is inaccessible or damaged.
No Outlook Dependency – Fully standalone; doesn’t require Outlook installation.
Filter Options – Export only what you need with advanced filtering by date, subject, etc.
Preserves Hierarchy – Keeps folder structure and metadata intact post-conversion.
Multiple Output Formats – Besides MSG, you can convert to PST, MBOX, EML, PDF, and more.
Naming Conventions – Customize output filenames for easier tracking and archiving.

Why It Stands Out

Compared to other email conversion tools, OST File Converter is:

Faster– Handles large files and complex folders in minutes.
Smarter– Built-in preview helps avoid exporting unwanted data.
Secure– Processes files locally without risking data leaks.
User-Friendly – Clean interface suitable for both IT professionals and casual users.

Whether you're migrating between platforms or preserving data for legal needs, this tool is engineered to handle real-world email management scenarios.

Pro Tips for Seamless Conversion

Back up original files before starting the conversion.
Use the preview pane to ensure you’re exporting the right data.
Apply filters to avoid bloating your output with unnecessary emails.
Choose proper output folders for better file organization.
Test a few MSG files post-export to verify integrity and metadata.

Final Thoughts

The shift from OST to MSG is no longer a technical headache—tools like OST File Converter make it fast, accurate, and stress-free. With support for corrupt files, batch export, and multiple file formats, it’s more than a converter—it’s a full-fledged email migration solution.
