Can I Convert OST to PST for Free Without Size Limits?

Free conversion without size limits is usually not possible with reliable tools. Freeware versions often impose restrictions to prevent large exports. If you are working with a small OST file, manual export via Outlook may work. However, for large or enterprise mailboxes, a professional OST to PST converter is the safest option.
Converting OST to PST without size limits using a free tool is generally not feasible. Most free converters impose strict limitations on mailbox size or number of emails. Manual methods through Outlook also fail when OST files are large, corrupted, or orphaned.
