Migrating from one email platform to another is always a tough task, especially from Outlook to Gmail. Though Exchange administrators can sync Exchange mailbox with Gmail (via GSMME) to migrate mailbox data directly to Gmail, there is no direct method to import OST file data in Gmail.
An indirect method can help Outlook users to import OST file data in Gmail:
- Export OST file to PST file
- Import PST data with the help of G Suite Migration for Microsoft Outlook (GSMMO).
Export OST file to PST file:
Microsoft Outlook provides an option to open and export mailbox data to PST file format.
- In Outlook, go to Files and click Open & Export
- Then, Import/Export wizard
- Click Export to a File and select Outlook Data File (.pst)
- Select the folder to export and click Next
- Click Browse to select the location for saving the exported file
- Click Finish and the selected mailbox folder is saved in PST format
- Repeat the process to save other folders
Events such as orphaned OST file due to Exchange Server crash and inaccessible OST file due to employee exit or when Outlook is not configured, does not allow users to access the OST file. In that case, Import/Export Wizard is unable to export OST file data to Personal Folders. Such problems can be resolved with the help of OST to PST converter software.
Also, OST converter software allows ‘batch conversion’ of multiple OST files into PST format thus helping in importing data from multiple Outlook data files in a single process.
Software such as Stellar Converter for OST helps select orphaned or inaccessible OST and convert it into PST file. The software also forms a batch of multiple OST files to convert them all to corresponding PST files in a single process.
Download the software and follow the steps for OST to PST conversion:
- On the Home Screen of Stellar Converter for OST, click Browse to select the OST file. Alternatively, click Find to search OST file.
- Click Convert to start the conversion process.
- The software converts OST file into PST format.
(Alternatively, click Batch Conversion from the Home ribbon and select multiple OST files to convert) option available in Technician version.
- Verify mailbox items and click Save Converted File
- Select the checkbox for PST file, click Browse to select a location and click OK.
OST file is saved
as PST file.

Quite a few users have a query regarding ‘importing OST file data in Gmail’. In this post, we presented the steps to export Outlook data to PST through Import/Export wizard and import that data in Gmail with the help of G Suite Migration for Microsoft Outlook.
Users may not be able to export their OST file data to PST when the Outlook account is not configured. If such a problem occurs, it can be resolved by using OST to PST Converter software . The software helps to find inaccessible and orphaned OST files and converts them into PST.
Another major advantage of software is that it creates a batch of multiple OST files and converts them into PST files in a single process. Later on, users can export data from multiple PST files to Gmail.
