Ways to Import OST File to Gmail

Read time 13 minutes

Microsoft Outlook stands as the most relied upon and extensively utilized email client. Within Outlook, there are two prominent file formats in use, PST and OST, associated with POP and IMAP accounts, respectively. In this article, we will explore methods for importing OST files into Gmail.

How does OST Work?

Offline Outlook Data File, or OST, is employed with account types like IMAP, Office 365, and Exchange to maintain a synchronized copy of your mailbox data on your local system. While working offline, you can access Outlook but won’t be able to send emails. Once server connectivity is reestablished, any modifications made to your OST file during the network interruption will synchronize with the server. In essence, your OST file data will be brought back into alignment with the server data.

Now we will focus our effort on the problem in hand- importing OST files to Gmail.

Using Manual Method

• Step 1: Locate your OST Files
• Step 2: Export your OST File as PST
• Step 3: Import PST to Gmail via. G Suite Migration for Microsoft Outlook (GSMMO) tool

Importing OST files into Gmail directly is not a feasible option. Therefore, it’s advisable to convert them to PST format beforehand. It’s worth noting that OST files often contain email data from third-party accounts (previously configured in your MS Outlook desktop client using IMAP settings), such as Gmail, AOL, or Yahoo.

To import OST files, one needs to find the location first. One can easily do that by following the steps mentioned below:

Step #1 Locate your OST Files

1. Click File > Account Settings > Account Settings.



2. Now, click on the Data Files tab, select any OST file, and click on Open File Location button.



Note: Generally, OST files can be found here irrespective of the Outlook version-

C:\Users\user\AppData\Local\Microsoft\Outlook

Note: It is to note that the AppData folder might be hidden; hence, the user has to unhide it first. To do so, in C:\Users\user, click on View tab > Options. Go to the View tab, expand Hidden files and folders, and select Show hidden files, folders, and drives.

Step #2 Export your OST File as PST

1. In MS Outlook, click on the File tab > Open & Export > Import/Export. This will open up the Import and Export Wizard.
2. Here, select the Export to a file option and hit Next.



3. This will open up Export to a File dialog window, select Outlook Data File (.pst) option and hit Next.



4. Now click on the required email account and select the item that you want to export as a PST file and hit Next.



5. Now click on the Browse button to save the PST file to the desired location and hit Finish.

Congratulations! You have successfully converted an OST file to PST. Now we will explore ways to import this file to Gmail.
