How to Import OST File to Gmail Manually?

Are you searching for a solution to import OST file to Gmail Manually? If your answer is yes, then this blog is very helpful for you. Here we will discuss the best workarounds by which you can upload OST to Gmail.

Microsoft Outlook used two file formats for storing data, i.e., OST and PST. The OST (Offline Storage Table) is used to store and synchronize a copy of your mailbox information on the system. While you are working offline, you can use Outlook but cannot send emails. Once server connectivity is restored, any changes made to your OST file will be synchronized with the server. In simple terms, the OST file is an offline file that is used for offline wok (without an internet connection).

Now, let’s move to the solution to import and open OST file in Gmail account.
