User Query:

My old Outlook stopped working, and now I have this .ost file sitting on my desktop, but I have no idea how to get those emails into my Hotmail account. Is there any way to import an OST file directly into Hotmail without any hassle or complications?

Summary: If your Outlook profile got corrupted or deleted, your OST file becomes inaccessible, and you are not able to drag it into Hotmail. There’s no direct import option built into Windows or Outlook to import OST to Hotmail. This blog walks through a manual workaround that works in basic situations, and a dedicated tool called CloudXena OST Converter Tool that handles the full migration without needing a working Outlook profile, including emails, contacts, and calendar data.

Why Should We Import OST File to Hotmail?

Once your Outlook profile breaks or gets deleted, that OST file is basically stuck and unusable.
Hotmail keeps your emails in the cloud, so a crashed PC won’t take your data down with it.
You can check old emails from your phone, laptop, or any browser without needing Outlook open.
Hotmail syncs everything on its own, so you’re not manually backing up files every few weeks.
Contacts and calendar entries move over, so you’re not starting from scratch on a new setup.
Switching laptops or operating systems becomes way less painful when everything lives in your Hotmail account.
Old emails stay searchable and intact, which matters a lot when you need something from years back.
It’s just easier to share stuff and work with others when your data lives in an actual email account.

Manually Import OST to Hotmail Using Microsoft Outlook

Manual methods work more as an indirect approach rather than a direct OST to Outlook.com transfer. Still, if done carefully, they can help you move your data without much trouble. Here’s a cleaner and easier-to-follow version of the process:

Steps to Migrate OST to Hotmail

Open Microsoft Outlook on your computer.
Next, you need to go to File -> Open & Export -> Import/Export.
Then, select Export to a file and click Next.
Afterwards, choose Outlook Data File (.pst) and proceed.
Select the mailbox (OST data) you want to export and save it to a location on your system.
Now, add your Outlook.com (Hotmail) account to Outlook using IMAP settings.
Now, go to File -> Open & Export -> Import/Export.
After that, choose Import from another program or file -> Next.
Select the Outlook Data File (.pst) and browse the PST file you created earlier.
Finally, select your Outlook.com mailbox as the destination and complete the import process.

Drawbacks of this Manual Approach:

The whole process can take quite a while.
You might notice duplicate emails after completing the import.
Some attachments or email details may not come through exactly as expected.
Outlook must be installed and set up correctly for this method to work.
Handling multiple OST files this way isn’t practical.
Results aren’t always perfect, so you may need to double-check your data afterward.

Final Words

Your folders stay intact, big files aren’t a problem.
