What is MBX file?

The .MBX file is a mail file. It is used by Microsoft Outlook Express software. A mailbox or its item (e.g. folder) is saved there. In addition to the directory structure, emails are also stored there. The file can also be used as a copy of your mail if copied to another location. Several other e-mail programs used the .MBX files, but most of them are no longer supported, and so is the free Outlook Express.

How to open MBX file?

The main problem with Outlook Express Mailbox is that the MBX file is incorrectly associated with programs. This is manifested by the fact that MBX files open in unusual applications or do not have an assigned program. This can be quickly resolved by following the instructions below.

The first thing you should do is just "doubleclick" on the MBX 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 Outlook Express

In this case, you should first verify that the Microsoft Outlook Express application is installed on the computer. To do this, enter the name Microsoft Outlook Express into the system search engine. If we do not have this program, it is worth installing it, as it will help you automatically associate the file MBX with Microsoft Outlook Express. Below is a list of programs that support the file MBX.

Step 2. Create association of Microsoft Outlook Express with MBX files

If the application is or has been freshly installed, but the MBX file still does not use the Microsoft Outlook Express program, it means no association. It is most convenient to call the context menu with the right mouse button and select Properties. 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. 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 MBX file with the Microsoft Outlook Express program.

Step 3. Update Microsoft Outlook Express to the latest version

If, despite the association of the Microsoft Outlook Express program with the Outlook Express Mailbox 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 MBX file

If the above steps do not help, you can assume that the file itself is not correct. The most common file problems are:

The affected file may be 0 KB or smaller than expected. Usually this applies to MBX 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 virus scan using an up-to-date antivirus program should fix the problem. 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 MBX file. As a result of the scan, sometimes it is not possible to recover MBX files, which are deleted if there is a backup of this file, then after restoring it, it must also be scanned.
A typical compatibility error - the program does not support the older version of the MBX file. These problems are known and are often very easy to fix using the software developers's website.
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 MBX file corruption. The easiest way is to restore the file from a backup, if there is one, or contact N/A
The program indicates that the file is encrypted or corrupted. The encrypted MBX 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.
Some of the system directories are excluded from modification. These directories are write-protected to them and it's very hard to fix this problem. Copying the MBX file to another location will fix the problem.
This problem only occurs with more complex files. You may find that another program you are using is preventing you from working with the file. Running programs (including those in the background) should be verified. Sometimes it is necessary to wait a while before referencing the MBX file again. Some anti-virus or backup software may occupy the MBX file for a certain period of time. If the problem persists, restart the machine.
