Launch the OLM Converter Tool as an administrator on your OS.

• Click the buttons Select OLM File(s) and Select Folder to add the single or multiple OLM files or folders with many OLMs from the system.
• Use the Remove Selected and Clear List buttons to remove unneeded files from the software, added accidentally.

Browse the OLM files/folders on your system and click Open to add them to the software wizard. You can even directly drop OLM files in the software by dragging them from the OS. Tap Proceed.

Once the file is added, click Expand All Folders to check all the files and folders in the file. Also, use the Search Folders option to look for a specific folder in the tree with a keyword.

• Preview the files you have added using the advanced preview panel in the software wizard.
• Use the Advanced Search option to locate specific emails using a keyword on the basis of To, From, or Subject.
• Double-click and the preview dialog appears, where you can check data by HTML Body, Plain Text, Attachment, Calendar, Contact, Header, MIME, and Raw HTML.

If you cannot preview emails in the software or want to check them on the web. Then, check the box beside the Open in browser (if preview fails) option, and check your OLM data before conversion.

Select the files and folders to convert from the expanded tree structure hierarchy. Use Collapse All Folders to sum up the tree view. Then, click on the Proceed button to move further.

To convert OLM emails to another format, select Export File Format and pick your desired one from the drop-down menu. Let’s say we pick Email Message (.EML).

You have the choice to explore optional features and filters. These include:

• Date Range Filter: The user has the option to migrate selective emails in a certain time period by adding a start and an end date.
• Custom Output Folder: Assign a custom name to the newly created folder for quick identification at the destination.
• File Naming Policy: Pick a specific style to save your resultant file name in that order. Say, Subject, Subject_Date, etc.
• Skip Existing Exports: To avoid the OLM files that have already been converted once for no duplicacy. If none exists, a pop-up appears; click OK.

Note: These Basic filters are the same for every file format you choose.

You can explore a few more filters for advanced management of your OLM before final conversion:

• Duplicate Detection: Exclude identical emails based on To, From, Body, Subject, and cc.
• Attachment Handling: The user has the option to exclude the OLM attachment files, save them separately, or insert them into the same file during the migration process.
• MBOX Segmentation: You can divide the large-sized MBOX files based on a specific size limit or create a single MBOX per folder.
• PDF Size Restriction: Store your PDF files in smaller chunks with a defined size limit to handle storage efficiently.
• PST Segmentation: Divide your large PST by MB or GB into smaller chunks to manage.

Note: The advanced filters for MBOX, PST, and PDF are only available when you pick that specific file format in the saving option.

Click the Browse button to pick a target location of your choice and tap Open to select it.

Finally, press Start Export to save the resultant EML file on the OS at the specified location.

Press the Stop Process button if you want to halt the conversion process in between due to any unavoidable factor.

Once the migration is successful, click the Close button to exit the pop-up. Additionally, press the Export Log button to obtain a comprehensive report of the OLM migration. Use Start New Export to restart the OLM conversion process.

Further, you can pick any email client to export your emails into. Here, we opt for IMAP.

Further, enter the email address, app password, port no. , and IMAP host credentials to sign in to the target account. Use the Server List button to enter the correct host. Press Authenticate to verify.

Ensure your account is already logged in for easy access. A message as follows is displayed after verification.

Either way you choose to log in to Gmail, you will receive the same filter options. These are:

• Date Range Filter: The user has the option to migrate selective emails in a certain time period by adding a start and an end date.
• Custom Output Folder: Assign a custom name to the newly created folder for quick identification at the destination.
• File Naming Policy: Pick a specific style to save your resultant file name in that order. Say, Subject, Subject_Date, etc.
• Skip Existing Exports: To avoid the OLM files that have already been converted once for no duplicacy. If none exists, a pop-up appears; click OK.

Here, you get the filter for:

• Duplicate Detection on the basis of To, From, Subject, Body, and CC to remove redundancy before the export.
• Attachment Handling: Choose to embed the attachments in the chosen IMAP account or save the data without attachments, i.e., exclude them.

Finally, click Start Export to initiate the process of OLM email migration.

Press the Stop Process button if you wish to halt in between for any reason.

In the end, you can check the migration status.

• Press OK for the pop-up stating to open the migrated OLM emails in IMAP.
• Press Close when the pop-up for export completion appears.
• Use the Export Log button to download a complete CSV report of the migration process.
• Also, press Start New Export to restart the OLM file conversion as required.
