Why MBOX Mail Moves to PST

Outlook stores mail in PST. A Thunderbird or Apple Mail archive needs that format before Outlook 365 can use it, and the folder tree must arrive as it was saved.

Core features

Four Moves for MBOX Mail Headed to PST

Install, load MBOX data, filter and save as PST.

Load

Choose MBOX Files or Folders

Run the software on Windows, press Open and load MBOX files or a folder through Email Data Files. Two choices send data to the panel.

Choose Files for chosen MBOX files
Choose Folders for a folder of MBOX files
No file size limit
Mail from many clients

MBOX folder tree with selection checkboxes

Folder selection

Select MBOX Folders for Outlook

The panel lists every loaded folder with a checkbox. Leave ticked what Outlook needs and clear the rest.

Checkbox on every folder
Structure listed as saved
Several files in one go
Cleared folders skipped

Message preview

Preview MBOX Data With Attributes

A preview panel opens messages and attachments before any PST is written. Mistakes in file choice show up in advance.

Content shows body text and attachments
Message Header lists sender, recipients and subject
Properties reports message attributes
Hex View and Raw Message expose the code of every mail

Selective backup

Apply Data Filters for Chosen Mail

Quick Search and Advance Search sort the data by date, email fields and keywords. Only the mail that matches goes into the PST.

Date range filter
Email field filter
Keyword search
To and From filter
Subject filter
One email address only

Output options

Select PST and Save

Open the export options, select PST and click Save. A single PST holds all mailbox data, or individual PST files can be made for every folder.

Before converting

Habits Before MBOX to PST Work

Three habits keep the Outlook import smooth.

Source clients

Note the mail client

Apple Mail, Entourage, Thunderbird and SeaMonkey files all load. A Google Takeout MBOX works too. Label the folder with its client name.

PST layout

Plan the PST layout

A single PST suits small mailboxes. Large MBOX data is safer in individual PST files, which avoids a bulky file and corruption risk.

Launch mode

Admin mode

Start the software with Run as Administrator. A separate Outlook install is not required.

Takeout mail has its own walkthrough in Migrate Google Takeout emails to Outlook and Open Google Takeout files.

Free demo

Test MBOX to PST Converter Free

A short demo install exports 10 data files per folder. Check the PST in Outlook before paying.

Before purchase

Manual Route vs MBOX to PST Converter

Moving MBOX mail into Outlook by hand means two mail clients and a lot of waiting. A bulk tool skips both. The table below sets the two routes side by side.

Task	Manual route	Tool
Cost	Free	$99 one time
One small folder	Import through two clients	Works too
Large MBOX file	Slow, may stall	No size limit
Outlook installed	Required	Not required
Folder hierarchy	Often reshuffled	Kept intact
PST layout	Not adjustable	Single or individual PST
Filters	None	Date, fields, keywords
Direct upload	Not offered	Thunderbird, Gmail, Office 365, IMAP

The green row marks where the manual route is enough.
