OST and eM Client are different from each other. Where one is a data file and the other is an email client. That is the main problem faced by users who want to import OST to eM Client, since there is no manual way for it.

However, this article will guide you in importing emails from OST file into eM Client with ease. Considering that, eM Client does not support the OST file importing directly, but there is a workaround that will be helpful. Today, in this article, we will discuss the best way to transfer OST file to eM Client.

Why Choose eM Client for Importing?

There are several reasons why users choose to transfer OST emails to eM Client. Some of them are:

1. An OST file is tied to a single Outlook profile, which limits accessibility. In contrast, eM Client supports multiple IMAP and POP3 accounts, making it more flexible.
2. By connecting multiple email accounts, eM Client allows effortless data management and transfer.
3. Advanced features and strong data security make eM Client a reliable alternative to Outlook OST files.
4. OST files are prone to corruption, which may cause data loss, while eM Client ensures better safety and stability for your mailbox data.
