How to open MMF file?
The most common problem when using Microsoft Mail Message Format is that a specific MMF is not associated with the program. Thus, when you open MMF, the program selection wizard or some other program starts. This problem can be easily remedied.
The first thing you should do is just "doubleclick" on the MMF file icon you want to open. If the operating system has an appropriate application to support it and there is also an association between the file and the program, the file should be opened.
Step 1. Install Microsoft Mail
An often overlooked issue is to make sure that Microsoft Mail is installed on the computer. The easiest method is to use the system search engine by entering the program name Microsoft Mail in it. If we do not have this program, it is worth installing it, as it will help you automatically associate the file MMF with Microsoft Mail. Below you will find a list of applications that support MMF files.
Programs to open MMF file
Remember to download programs supporting MMF files only from verified and safe sources. We suggest using the websites of software developers.
Step 2. Create association of Microsoft Mail with MMF files
If, despite the installed application, the MMF file does not start in the Microsoft Mail application, you must create a file association. It is most convenient to call the context menu with the right mouse button and select Properties. The displayed window will contain information about the program that supports this type of file. Using the "Change" button we can set the program to handle this type. The program should be visible in the window, otherwise it should be selected manually using the "Browse" button and the program installation directory should be indicated. Checking the "Always use the selected program ..." box will permanently associate the MMF file with the Microsoft Mail program.
Step 3. Update Microsoft Mail to the latest version
If, despite the association of the Microsoft Mail program with the Microsoft Mail Message Format file, the file still does not open, check the program version and possibly update it to the newest version. In this case, use the Microsoft Corporation website or update the program from the application.
Step 4. Check for the following problems with the MMF file
The problem may also be with the file itself if the above steps don't 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 MMF files downloaded from the Internet in case the download did not finish properly. The file should be downloaded again, making sure that the process has finished correctly.
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. Some antivirus vendors also provide free online scanners. The scan should cover the entire computer, not only the MMF file that we want to open. Sometimes virus-infected MMF files cannot be recovered, so make a backup in advance.
A typical compatibility error - the program does not support the older version of the MMF file. 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 the failure. The repair method must be adapted to the type of file and damage. Some programs offer the ability to automatically repair MMF file corruption. You can restore the file from a backup or use Microsoft help.
When reading, a message appears that the file was encrypted or corrupted. The encrypted MMF files can be used by the device on which they were encrypted, on any other device it is required to have the appropriate cryptographic key and decrypt the file before its recovery.
The operating system protects files in some locations (e.g. the root of the system partition) against unauthorized access. The problem is only writing to the file, not reading it. If possible, you can try to move the MMF file to another location.
This problem usually affects more complex files. In this case, the MMF file is blocked by the first application to open it. Closing other programs should help. Sometimes you have to wait for the session to the file MMF to close. Antivirus programs or a backup being made may lock the file for a while without the user's knowledge. If this does not work either, restart the device.
