You can import MSG to Google Workspace either manually or professionally. With the manual process, you would first need to convert the MSG files to a suitable format (such as EML or a CSV file) using Outlook clients or third party converters. Then, you would use either "Data Migration" in the Google Workspace Admin Console to upload EML files or drag-and-drop the emails into a Gmail account. It is very important to ensure that you map all fields correctly and to check that the import has completed properly.

However, Google Workspace does not officially support importing MSG files and thus requires conversion first. Additionally, large files may not be transferred, and metadata (including timestamping) may also be inaccurate when transferred. And because the manual process is very time-consuming for importing a large volume of data, it is best to use a paid service for bulk importing MSG files into Google Workspace

MigrateEmails MSG Converter Tool is a professional software application to efficiently convert Outlook MSG files to G Suite (Google Workspace) accounts. It delivers accurate email migration with attachments, metadata, and folder hierarchy without data loss or corruption.
