target audience

To join multiple individual Outlook .msg files into a single file, you generally need to combine them into an Outlook Data File (.pst) or a single PDF document. Because Microsoft Outlook does not have a native “Merge MSG” button, users typically rely on either a manual drag-and-drop method within Outlook or automated third-party software (such as MailsWare, SysTools, or RecoveryTools) to batch-process the files. Here is exactly how to use both approaches to achieve this.

Method 1: The Automated Software Approach (Fastest for Bulk Files)

Dedicated “MSG to PST Converter” utilities are designed to merge thousands of scattered .msg files into one master .pst file in just a few clicks. Step-by-Step Instructions:

Download and Launch: Open your chosen MSG merge utility on your PC.

Import MSG Files: Click Select Files or Select Folder to upload all the .msg files you want to combine.

Choose Output Format: Select PST (or PDF if you want a document archive) from the available saving options.

Set Destination: Click Browse to choose where you want to save the new, combined file on your computer.

Merge: Click the Convert or Merge button to generate your single consolidated file.

Note: Automated tools are highly recommended for large datasets because they preserve your original folder structure, email metadata (To, From, Date), and file attachments without risking data loss. Method 2: The Manual Method (Using Microsoft Outlook)

If you already have Microsoft Outlook installed and only have a small handful of files, you can merge them into a single .pst archive for free. Step-by-Step Instructions:

Create a Blank Folder: Open Microsoft Outlook, right-click on your primary mailbox, and select New Folder. Name it something like “Merged MSGs”.

Drag and Drop: Open the folder on your computer where your .msg files are saved. Select them all (Ctrl + A), then drag and drop them directly into your new Outlook folder. Export to PST: Click File > Open & Export > Import/Export. Select Export to a file and click Next. Choose Outlook Data File (.pst) and click Next.

Select the Folder: Highlight the specific “Merged MSGs” folder you created in Step 1, make sure “Include subfolders” is checked, and click Next.

Save the File: Click Browse to name your new combined file and choose where to save it, then click Finish.
