How to Import OST Files to IMAP Server Account Directly

Understanding OST and IMAP Files

What is an OST File?

An OST file is a local copy of your mailbox data that Outlook creates when you connect to an Exchange server. It allows users to access their emails, calendars, contacts, and tasks without being connected to the Internet. Any changes made while offline are synchronized with the server once connectivity is restored.

What is an IMAP Server?

IMAP is a standard protocol for accessing email from a remote server. Unlike POP (Post Office Protocol), which downloads emails and removes them from the server, IMAP allows users to access their emails on multiple devices while storing them on the server. This makes it a popular choice for managing emails across different platforms.

Why Do We Need to Migrate from Outlook OST to IMAP?

There are several reasons one might want to import OST files to IMAP server. Here, we will mention some of the main reasons that led to the Outlook OST to IMAP migration.

• OST files are tied to a specific computer or Outlook profile. While IMAP allows email data to be stored on the server and synchronized across multiple devices.
• With IMAP, email data is stored on the server and continuously synced with all devices, reducing the risk of synchronization conflicts.
• Backup and migration can be complex with OST files, since emails are stored on the server, migration to a new device or email client is simple.
• If the OST file gets corrupted, it can be difficult to recover emails without the help of advanced repair tools. Hence, users prefer IMAP as compared to OST.
• Multiple users can access the same IMAP mailbox simultaneously, which, makes it easy for teams to collaborate on shared email accounts.

When you import Exchange OST to IMAP, you can get more flexibility, better synchronization, and easier access across multiple devices. Also, it provides a modern and versatile email experience. Now, we will move to the methods to migrate from Outlook to IMAP.

How to Import Outlook OST to IMAP Account

Unfortunately, Outlook does not provide a direct method to import OST files into an IMAP account. You have to go through multiple stages in the manual import process. To directly perform Outlook OST to IMAP migration, users must depend on an alternative approach. The upcoming section will outline both manual and automated methods to help you import OST files into an IMAP account efficiently.

Method 01: Native Solution to Import OST Files to IMAP

To migrate Outlook OST files to an IMAP account manually, you can’t directly convert an OST file to an IMAP format. However, you can perform the migration by exporting data from the OST file to a PST file and then uploading that data to an IMAP account. Here’s how to do it step-by-step:

Step 01: Export OST Data to a PST File

You need to export the OST file data into a PST format, as Outlook cannot directly import an OST file into another account.

1. Open Outlook and go to the account with the OST file.
2. Thereafter, click on File in the top left corner.
3. Select Open & Export, then click Import/Export.
4. In the Import and Export Wizard, select Export to a file >> Next.
5. Choose Outlook Data File (.pst) and click Next.
6. Select the folder you want to export and verify that the option Include subfolders is checked.
7. Lastly, choose a location to save the PST file, then click Finish.

Step 02: Configure an IMAP Account in Outlook

In the second step, you will need to configure your IMAP account in Outlook if it’s not already added.

1. Again, go to Outlook and go to File >> Add Account.
2. Enter your IMAP account email address and click Connect.
3. After that, select IMAP as the account type.
4. Enter the incoming and outgoing server details provided by your email provider (usually something like imap.mailprovider.com for incoming and smtp.mailprovider.com for outgoing).
5. Enter your username and password and click Next.
6. Outlook will test your account settings; click Finish when done.

Step 03: Import PST to IMAP Account

Once the PST file is exported and your IMAP account is set up in Outlook, you can import the data into the IMAP account.

1. In Outlook, go to File >> Open & Export >> Import/Export.
2. In the wizard, select Import from another program or file and click Next.
3. Choose Outlook Data File (.pst) and click Next.
4. Browse and select the PST file you created earlier.
5. Select the IMAP account from the list to import the data into it.
6. Tap on Include subfolders, then click Finish to migrate Outlook OST files to IMAP.

Once imported, Outlook will sync the data with the IMAP server. It may take some time depending on the size of the data and your internet connection speed. After syncing, your data will be available across all devices connected to the IMAP account.

Limitations Associated With the Manual Method

When manually importing OST files to IMAP accounts, there are several limitations that users should be aware of:

• Outlook doesn’t provide a direct option to import OST files to IMAP. Thus, it requires several steps to perform the task.
• It requires Outlook to be installed and the OST file to be associated with an active Outlook profile.
• During the manual process, there is a risk of data loss, particularly if the conversion steps are not handled carefully.
• If your OST file is corrupt or inaccessible, the manual process won’t work properly.
• Some IMAP servers have storage or message limits, so large OST files may need to be split manually.
• The manual process requires a good understanding of both Outlook and email configuration.

To avoid these limitations, users often turn to the automated solution, which simplifies the process and offers more control over the conversion and import of data into IMAP accounts.

Method 02: Automated Solution to Export OST Files to IMAP Server
