Summary: This blog discusses the most searched query “how do I merge two Outlook data files?” Here you will know the steps to merge Outlook data files manually and automatically.

Outlook is the most popular desktop-based email client. It offers users to create several email accounts to store their data. Outlook supports storing all data items such as email messages, calendar items, contacts, and others in PST file format. But when it’s time to manage all these PSTs, users face many problems like hanging, being unable to open PST files, deleting PSTs, etc.

To get rid of all these problems, merging all Outlook PST files into a single file is the topmost solution. Therefore, users are looking for a way to merge two PST files in Outlook.
