Transferring Outlook folders from one account to another is possible using both manual and automated solutions. The manual method involves exporting your Outlook data into a PST file and then importing it into the target account.

Steps:

1. Open Microsoft Outlook on your system.
2. Click on File > Open & Export > Import/Export.
3. Select Export to a file and click Next.
4. Choose Outlook Data File (.pst) and click Next.
5. Select the folders you want to transfer.
6. Browse a location to save the PST file and click Finish.
7. Now, sign in to the destination Outlook account.
8. Go to File > Open & Export > Import/Export again.
9. Choose Import from another program or file.
10. Select the saved PST file and import it into the new account.

Although this method is free, it can be time-consuming and requires multiple steps. To simplify the process and avoid potential errors, many users prefer using a professional solution like the Advik Outlook PST Converter. This tool can move Outlook folders from one account to another while preserving email structure, attachments, and all associated properties.

1. Download and install the Advik Outlook PST Converter on your system.
2. Launch the tool and choose your configured Outlook profile.
3. Choose the mailbox folders.
4. Select PST as a saving option.
5. Apply filters if needed (date range, folders, etc.).
6. Browse target location and click the Convert button.
7. Now, open another Outlook and import the exported .pst file via the Import/Export feature.

This approach is faster, more reliable, and ideal for handling large Outlook data without any risk of data loss.
