In case of the required transfer of an Outlook OST file into Gmail, there is an EmailSoftware OST to Gmail Migration utility available. Not surprisingly, this amazing tool allows you to retrieve OST files (i.e., attachments) in Gmail or Google Suite accounts. It provides capabilities such as batch import, targeted data movement to a folder, and unrecoverable data loss, i.e., all email properties, attachments, and embedded images can be retained. The tool is nontoxic, verified, and simple to use with a scanning/preview option so that OST files can be validated before conversion. It also generates a log file for process monitoring and is a reliable solution for OST to Gmail transfer.
