Before moving to the step-by-step solutions, let’s first understand a common user concern.

User Query;

“Has anyone migrated emails from Mailbird to Office 365? I want to move all my emails to Microsoft 365 for better management. Is there a direct way to transfer everything without losing folders or attachments? Also, will it cause issues if I configure my Office 365 account in the same Outlook profile?”

If you are also facing the same situation, this guide will help you choose the right method.

Why Migrate from Mailbird to Office 365?

Many users prefer Microsoft 365 (Office 365) because of its advanced features and business benefits.

Mailbird is a desktop email client. It manages multiple email accounts in one place. However, it does not provide cloud hosting. On the other hand, Microsoft 365 is a cloud-based platform that offers better scalability, collaboration tools, and security.

Here are some key reasons to migrate:

  • Cloud-based email access
  • Advanced security features
  • Large mailbox storage
  • Access to Outlook Web App
  • Integration with Microsoft apps (Word, Excel, Teams, OneDrive)

Prerequisites Before Migration

Before starting the migration process, make sure:

  • You have Office 365 admin or user account access
  • You know the login credentials of email accounts configured in Mailbird
  • Stable internet connection
  • Proper backup of important emails (recommended)

There is no direct built-in option in Mailbird to export emails directly to Office 365. However, you can use these two manual approaches:

  • Using Outlook (Export & Import Method)
  • Using IMAP Synchronization

Let’s understand them in detail.

How to Migrate Mailbird Emails to Office 365 Using Outlook

Mailbird stores emails locally by syncing IMAP accounts. So, you can export data via Outlook in PST format and then import it to Office 365.

Steps:

  1. Configure the same email account (used in Mailbird) in Microsoft Outlook.
  2. Wait for full mailbox synchronization.
  3. Go to File > Open & Export > Import/Export.
  4. Select Export to a file and choose Outlook Data File (.pst).
  5. Save the PST file.
  6. Now configure your Office 365 account in Outlook.
  7. Go to File > Open & Export > Import/Export.
  8. Import the previously created PST file into Office 365 mailbox.
  9. Finally, your Mailbird emails will be available in Office 365.

Challenges of This Method

  • Time-consuming process
  • Requires Outlook installation
  • Risk of incomplete sync
  • Not suitable for bulk users
  • Possible data corruption
  • Manual effort required
