Use Cases

When Do You Need PST Merge Tool?

If users have multiple Outlook accounts they will obviously have multiple PST files. However, manual process of merging requires to open each file in Outlook and to copy the emails from one PST to another by dragging & dropping. This takes a lot of time if you have big mailboxes. In such a scenario, a PST merge tool makes the entire process easy by merging multiple PST files into one single PST file in one go.

Older Outlook versions generate ANSI PST files whereas newer versions generate Unicode format which leads to compatibility issues while merging them manually. The software solves such complexities by supporting ANSI & Unicode PST files. It will help you to merge old and new PST files without any compatibility issues.

Manually merging contacts or calendar data from multiple PST files requires copying each entry individually, which is very time consuming and error prone. When you add PST files in the software, it displays all the folders and then you can select specific folders like all contact folders from all PST files and merge them into a single PST contact.
