Core features
Five screens of Corbett EML to PST converter software, in conversion order.
Source files
Select Open, then Email Data Files, and add your EML files. EML to PST converter loads your mail into its panel, and no mail client is needed.
A spare PC with no mail client still works. EML to PST converter reads your files and leaves them as they were.
Batch loading
Select Choose Files for one EML file or a few. Select Choose Folders to load an entire directory of EML files in one step.
Loaded mail appears in one tree with a checkbox beside every item, so EML to PST converter handles many EML files in a single session. No file size limit applies.
Message preview
Click any message and a reading pane opens beside five analysis views. Use them to confirm correct mail before EML to PST conversion starts.
Content shows the email body. Message header lists From, To, Subject and Date. Properties reports item data, while hex and raw message views show the stored mail.
Output formats
Select PST under Email Files in the Export menu. The same load also exports EML, MBOX, PDF and more, and the menu lists Gmail, Office 365, IMAP and Thunderbird for sending mail into an account.
Search by keyword first, then save only matched items. Quick search highlights hits in yellow, and Advance search checks every field or only name, subject, To, Cc and content.
Export options
Switch on open folder after export, skip greyed out folders, create empty folders and include email headers. For PST output, create an individual PST file for every folder, so every PST stays small and easy to open.
Select Browse to choose a destination, then Save. Live progress shows every folder as it converts, and Open Folder takes you to your PST output.
Working process
Four steps take your EML files to PST. Try them on a few files in free demo first.
Add your EML files

Set options, select Browse for a folder and press Save. Live progress shows every folder, and Open Folder takes you to your PST output.

Earlier, my friend suggested converting EML to PST online, and I tried the free online service, but they are not accurate and store data for more than 48 hours on the server.

Before conversion
Three short checks keep your EML to PST conversion clean.
Make a EML copy
Back up your EML files on a safe drive before you start. EML to PST converter opens files read only, and a spare copy keeps the original safe.
Choose all mail or chosen items
Convert every folder at once, or limit the job to the folders and items you need.
Leave space for output
PST output needs free room on the destination disk, and one PST for every folder keeps files small.

Best practice
A conversion only helps if your mail arrives complete. Four habits keep your data safe through it.
Back up first
Copy your original EML files before you start. Keep 3 copies on 2 types of media with 1 copy off site.
Start with one file
Convert one small EML file with EML to PST converter and open a few emails in PST. Catch a wrong setting before a large job.
Check the count
Compare the message count in the folder tree with the mail in your output before you close the job.
Keep originals until checked
Store your source EML files until counts match. Delete them only after you open converted mail.
