If you're moving from Outlook or Microsoft 365 to Hostinger Email, you may notice that the automatic migration tool doesn’t work. Microsoft Exchange and some Outlook-derived email accounts no longer support standard IMAP migration by default.
But no worries — you can still migrate your emails manually by exporting and importing them through the Outlook app.
How to Migrate Your Outlook Emails to Hostinger
Before importing your emails: Ensure your original Outlook email account is still active on your desktop app.
Step 1: Export data from Outlook
Use the built-in export feature to generate a backup:
On Windows, export your data as a .PST file. (Check Windows export guide)
On Mac, export it as a .OLM file. (Check Mac export guide)
Step 2: Create Your Hostinger Email Mailbox
Ensure your Hostinger email plan is set up and your mailbox is created and connected.
Step 3: Add Hostinger Email to Outlook
You can add it as an IMAP account through Outlook. For best compatibility, you must connect it using a Microsoft-based profile (e.g., your @hotmail account). Avoid newer 2023-onwards versions and follow Setting Up Email on Microsoft Outlook 2019, 2016, and More. Read more about Outlook’s limitations here.
Step 4: Import Your Email Backup
Once connected, open your Hostinger email account on Outlook and:
Go to the File tab and select Open & Export > Import/Export
Choose your .PST (Windows) or .OLM (Mac) file
Select your Hostinger email as the target inbox
Once the process is done, your messages will start syncing to your Hostinger mailbox.
Keep in mind that the "File" tab might not appear depending on your Outlook app version. In such cases, look for the "Open & Export" tab.
Notes:
Large backups may take more time to import and sync.
Keep both accounts active in Outlook until the import completes.
Want to confirm everything synced? Just log into Webmail or re-check in Outlook.
Email duplication can happen with Outlook if you use an IMAP connection while connected to another device via POP3 and have enabled "Leave a Copy on the Server.
