How can I import PST file to IMAP server?
The easiest way to import PST to IMAP server depends on the amount of data you need to move. If you only have a few emails, you can configure the IMAP account in Outlook and move the emails using the drag-and-drop method. However, this process can become slow and time-consuming when working with large PST files.
For larger PST files, I prefer using Advik PST File Converter. It provides an easier way to transfer PST data and helps maintain the original folder structure and attachments. You can also select the specific data you want to migrate instead of transferring the entire PST file. For large PST files or multiple mailboxes, using a dedicated PST conversion tool can be more convenient than handling the migration manually through Outlook.

You can import a PST file to an IMAP server using Outlook or a dedicated migration tool. For a small PST, add your IMAP account to Outlook, open the PST from File > Open & Export > Open Outlook Data File, and copy the required emails or folders into the IMAP account. Outlook will synchronize them with the server.
For larger PST files or multiple folders, Softaken PST to IMAP Importer can simplify the process. It supports PST and OST files, email attachments, folder hierarchy, SSL/TLS or STARTTLS for IMAP, duplicate protection, and pause/resume. It can also generate HTML migration reports.
For a few emails, Outlook is sufficient. For bulk PST to IMAP migration, a dedicated importer can reduce manual work and make the transfer easier to manage.
