Step 2. Create association of Microsoft Exchange Server with TNF files

If the application is or has been freshly installed, but the TNF file still does not use the Microsoft Exchange Server 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 select the desired program. 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 TNF file with the Microsoft Exchange Server application.

Step 3. Update Microsoft Exchange Server to the latest version

If, however, after binding Microsoft Exchange Server with Transport Neutral Encapsulation Format there were still problems, you should update the program to the latest 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 TNF file

The problem may also be with the file itself if the above steps don't work. The most common file problems are:

Very often, the file may be size 0 or incomplete. This is most often caused by a problem while downloading the TNF file. Downloading the file again should fix the problem.
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. Some antivirus vendors also provide free online scanners. For the best results, we will scan the entire operating system, not just our TNF file. Sometimes virus-infected TNF 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 TNF files changes over time. These problems are known and are often very easy to fix using the software developers's website.
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 TNF file corruption. You can restore the file from a backup or use Microsoft Corporation help.
The program indicates that the file is encrypted or corrupted. The encrypted file TNF 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 of the system directories are excluded from modification. While there is usually no problem reading such a file, it may not be possible to save it. It is best to move TNF to a different directory.
This problem only occurs with more complex files. In this case, the TNF file is blocked by the first application to open it. Closing other programs should help. If the error persists after closing other programs, wait for a while. Antivirus programs or a backup being made may lock the file for a while without the user's knowledge. If the problem persists, restart the machine.
