Step 1. Install Pegasus Mail

Programs to open PMO file

Remember to download programs supporting PMO files only from verified and safe sources. We suggest using the websites of software developers.

Step 2. Create association of Pegasus Mail with PMO files

However, it may happen that the application itself does not cause the PMO file to open in the Pegasus Mail application, but you can set it manually. This option is available from the level of Properties of a specific file available in the context menu. Information about the file and the program that the file is associated with are available here. Using the "Change" button we can set the program to handle this type. It may happen that in the next window there will be no appropriate program - however, this can be corrected with the "Browse" option where you should manually indicate the program location. However, it is important to check the "Always use the selected program ..." box, this will allow you to permanently associate the PMO file with the Pegasus Mail application.

Step 3. Update Pegasus Mail to the latest version

The fault may also lie with the Pegasus Mail program, it is possible that Pegasus Mail Saved Message Format requires a newer version of the program. In this case, use the David Harris website or update the program from the application.

Step 4. Check for the following problems with the PMO file

Of course, it may happen that despite the above steps, the file still does not work. This could be due to the file itself, the cleanest issues are:

The affected file may be 0 KB or smaller than expected. Usually this applies to PMO files downloaded from the Internet in case the download did not finish properly. The only repair option is to download the file again.
The computer may have fallen victim to a computer virus or hacker. A quick virus scan using an up-to-date antivirus program should clear up any doubts. If this is not possible, you can use the online scanner. For the best results, we will scan the entire operating system, not just our PMO file. Sometimes virus-infected PMO files cannot be recovered, so make a backup in advance.
This can happen especially when the program is dynamically developed and the structure of the PMO files changes over time. Help should be sought from the software developer, as they usually recommend using free file converters or installing an older version of the program.
There can be many reasons for this. The repair method must be adapted to the type of file and damage. Sometimes the program itself has options to repair the most popular PMO file corruption. You can restore the file from a backup or use David Harris help.
The program indicates that the file is encrypted or corrupted. The encrypted file PMO except for the special designation, works normally, but only on the device where it was encrypted, before transferring it to another machine, decryption is required.
Some operating systems do not allow file operations in certain locations, eg in system directories or directly on the system drive. These directories are write-protected to them and it's very hard to fix this problem. It is best to move PMO to a different directory.
This can happen on a file that does not support multiple access. You may find that another program you are using is preventing you from working with the file. Closing other programs should help. Sometimes you have to wait for the session to the file PMO to close. Antivirus programs or a backup being made may lock the file for a while without the user's knowledge. If nothing helps, please reset the device.
