Manual Methods to Import Outlook OST to Google Workspace

To import OST to Google Workspace, you must follow a series of steps. Gmail does not support importing from an OST file, so you have to convert the OST file to PST first. Now, below you will find step-by-step instructions for each procedure and method through which you can import your OST emails into Google Workspace.

Method A: Using Outlook and GWMMO

Ensure you are logged in to the profile that generated the OST file.
In Outlook, click on File in the top left of the window.
Select the Open & Export option from the File menu, then click Import/Export.
Click Export to a file and Next, then select Outlook Data File (.pst).
Choose the mailbox or folders you want to export as a PST.
After that, choose a location to save the exported PST file. Click Finish.
Open your browser and sign in to your Google Workspace Gmail account.
Click on the gear icon at the top right and click See All Settings option.
After that, enable IMAP under IMAP Access.
Next, download the Google Workspace Migration for Microsoft Outlook tool on your specific system.
Then, open the tool and log into your Google Workspace account with your Gmail credentials.
Select Import from the PST file in the GWMMO tool.
Now, locate and select the PST file you wish to import.
Select which desired data you want to import.
Then, follow the prompt on the computer screen to complete importing.
In the end, you successfully do the task and verify it to avoid any data loss.

Method B: Manual Method Using IMAP

If you do not want to use the GWMMO tool, you can import the emails from PST to Gmail manually using Outlook and IMAP.

Open Outlook and go to File > Account Settings > Account Settings option.
Next, click New under the Email tab, and then add your Gmail account.
Click on the IMAP option and input your Gmail account information.
In Outlook, go to File > Open & Export > Open Outlook Data File.
After that, open the PST you converted earlier in the Select item.
Now that you have opened the PST file, you can view its folders in Outlook.
Here, you simply drag and drop the emails or folders from the PST into the Gmail folder in Outlook.
Now, this will synchronize the emails into your Google Workspace Gmail account.

Important Considerations Before You Import OST to Google Workspace

Folder Structure: Make sure that your folder structure is kept during the import. Gmail uses labels instead of folders.
Data Size: If your PST file is large, the import may take hours.
Email Limits: Gmail has certain sending and receiving limits. Be sure to be on the lookout for these limits when importing large volumes of emails. Gmail will temporarily suspend a user’s account’s ability to receive new emails when the quota is exceeded.
Nested Folders: If you have nested folders in Outlook, the import process should preserve that structure. Although Gmail doesn’t work with traditional folders, it should preserve your folder structure as labels.
Duplicate Emails: You may end up importing some duplicate emails if you are not careful when importing. Check and delete them manually if they exist.
