How it works

How Pegasus Converter Handles a Whole Mailbox

Each panel in the order a conversion uses it.

BitRecover Pegasus Mail Converter loading PMM files

Load PMM, CNM and PMI Files

A whole folder or one message

Open takes either a Pegasus mail folder or a single message file. Everything inside loads into the panel with its date, sender, recipient and subject, ready to read before anything is written.

  • Select Folder for a whole mailbox at once
  • Select File for one message or a handful
  • Neither Pegasus Mail nor Outlook has to be installed
  • Original files are opened for reading only

Select a PMAIL Folder

Browse a tree and pick a mail store

Pegasus keeps mail under a PMAIL folder with a subfolder for each user. The converter finds that folder itself. Browse to it by hand where the mail store has been copied somewhere else.

  • Finds the PMAIL folder automatically
  • Or browse the tree and pick it by hand
  • Original folder hierarchy carried into the output
  • Search a mailbox to find particular emails

Choose From Ten Output Formats

PST for Outlook, MBOX for Thunderbird

Saving Options lists every format side by side. Choose PST to land the mail in Outlook, MBOX for Thunderbird and EML for Windows Mail. PDF and CSV suit mail that has to be read without a mail client at all.

  • PST, MSG, EML, EMLX, MBOX and MBX
  • PDF, HTML, RTF and CSV
  • Create a new PST or add to an existing one
  • File naming by date, sender or subject

Convert a Whole Mailbox in Batch

Thousands of messages at once

Point the converter at a folder and it works through every message underneath it. The panel reports the folder in progress, the count finished and the overall position, so a large mailbox can be left running.

  • Current folder and running count on screen
  • Whole folders load in one pass
  • Attachments convert alongside their message
  • Runs offline, with nothing sent anywhere

Pegasus Mail Converter reads the mailbox and shows every message before payment. The first five files convert free.

Run the Free Demo

Export PMM and CNM Files to PST in Five Steps

Five steps from a PMAIL folder to a file Outlook opens. For the free manual routes, see our guide to converting Pegasus Mail to Outlook.

Install and open

Run the installer and start the wizard. Pegasus Mail itself does not need to be installed. Neither does Outlook.

Load Pegasus files

Click Open, then choose Select Folder for a whole mail store or Select File for individual messages. Browse to PMAIL and confirm.

Read a mailbox

Folders appear on the left with the names Pegasus gave them. Messages list with date, sender, recipient and subject. Open any of them to preview the body before converting, with the header metadata intact.

Pick an output format

Click Save and the format list opens. PST suits Outlook, MBOX suits Thunderbird, PDF suits archiving and CSV suits a spreadsheet.

Search a mailbox to find particular emails

Choose where the output goes and how files should be named, then start. Progress shows per folder while the batch runs.

Disk space it needs

Roughly what the mailbox already occupies. PST holds mail and attachments together, so allow a little more space than the PMAIL folder measures. Convert five files free before committing to the full run.

Why Pegasus PMM and CNM Files Will Not Open Elsewhere

Pegasus Mail stores each message in its own file under a PMAIL folder, in a layout it invented and never published. No other client reads it. Pegasus can save a selection of messages to disk as MBOX, but there is no bulk export and nothing that produces a PST.

PMM and PMI files

One file per mailbox

A PMM file holds a whole folder of mail and a PMI file indexes it. Double clicking either opens nothing.

CNM files

One file per message

New mail arrives as a CNM file named by a unique ID rather than by subject, which is why a folder of them gives no clue what they contain until something reads the headers. Messages delivered locally start with a Y and those downloaded over a POP3 or IMAP account start with a P.

Attachments

Inside the message

Documents, images and spreadsheets are stored inside the message file. Conversion decodes them and keeps them attached to the mail they arrived with, which the free trial shows on the first five.

Can Outlook Open a Pegasus Mail File Directly

No. Outlook reads PST and Pegasus writes neither PST nor anything close to it.

Renaming a CNM file to .eml produces a file Outlook still cannot open, because the encoding inside has not changed. Copying a PMAIL folder into an Outlook profile does nothing either. Something has to read the Pegasus layout and rebuild each message in a format Outlook can read, which is what a converter does.

Two ways people try

Renaming the extension

The name changes and the contents do not. Outlook still cannot open it.

Converting the mailbox

Each message is rebuilt as Outlook expects, with its date, sender, attachments and folder intact. Five convert free, so the result can be opened in Outlook before paying.

File types, output formats, trial limits and price

No. Outlook reads PST and Pegasus writes neither PST nor anything close to it. Renaming the extension changes the name and not the encoding inside, so Outlook still cannot open it. The mail has to be rebuilt in a format Outlook understands.

Under a folder called PMAIL, usually at C:\PMAIL, with a subfolder for each user account. Inside those sit the PMM, PMI and CNM files. Pegasus also runs from a USB stick without installing anything, so the folder may be on removable media or in a backup. Browse to wherever it now lives.

A PMM file holds a whole folder of mail and a PMI file indexes it. A CNM file is a single message, usually newly arrived and not yet filed. The converter reads all three.

No. Neither does Outlook. The converter reads the files directly, which matters when the machine that ran Pegasus is long gone and only a copy of the folder survives.

PST if the mail is going into Outlook. MBOX for Thunderbird and Apple Mail. EML for Windows Mail and Outlook Express. PDF or HTML where the mail needs reading without any mail client. CSV where it is going into a spreadsheet.

Yes. Documents, images, spreadsheets and anything else sitting inside a message are decoded and stay attached to the mail they arrived with.

Yes. Folders come out with the names Pegasus gave them, so an inbox stays an inbox and a filed folder keeps its name and its contents.

Save as PST, then in Outlook choose File, then Open and Export, then Open Outlook Data File. Point it at the converted file and the Pegasus folders appear in the folder list.

Yes. Saving Options offers Create New PST or Update Default PST, so converted mail can either go into a new file or be added to the PST Outlook already uses.

Yes. Select Folder loads everything beneath a folder and converts it in a single pass, which is what the dual loading option is for.

No. Source files are opened for reading and never written to. Run the conversion twice and the original mail store is exactly as it was.

Yes. Load the mailbox, use Search to find particular emails and select only the folders or messages you need rather than the whole store. Our Pegasus to Outlook guide covers the manual IMAP and EML routes if you would rather not buy anything.

The full software with every format available. It converts 5 files so the output can be checked in Outlook or Thunderbird before paying. A licence removes that cap.

Thirty nine dollars, once. There is no renewal, no per mailbox charge and no separate cost for individual formats. A 30 day money back guarantee applies.

Windows 11, 10, 8.1 and 7, plus Windows Server, in 32 and 64 bit.

No. Conversion happens on your own machine with no internet connection required, so mail never leaves the computer it is sitting on.
