Step 2. Create association of Microsoft One Note Mobile for iPhone with 1SP files

However, it may happen that the application itself does not cause the 1SP file to open in the Microsoft One Note Mobile for iPhone application, but you can set it manually. It is most convenient to call the context menu with the right mouse button and select Properties.

Step 4. Check for the following problems with the 1SP file

If the above steps do not help, you can assume that the file itself is not correct. This could be due to the file itself, the cleanest issues are:

Very often, the file may be size 0 or incomplete. This suggests truncating the 1SP file contents when downloading or copying. The only repair option is to download the file again.
The most common cause here is computer viruses. Perform a virus scan using available and up-to-date anti-virus software. 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 1SP file. As a result of the scan, sometimes it is not possible to recover 1SP 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 1SP 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.
The file may be corrupted in a number of ways. Repairing is very dependent on the file type. Some programs offer the ability to automatically repair 1SP file corruption. The easiest way to restore the file is from a backup or by contacting Microsoft Corporation, but this one can be expensive. Not all damage can be reversed.
The program can also signal the fact of encryption. The encrypted file 1SP 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. The problem is only writing to the file, not reading it. If possible, you can try to move the 1SP file to another location.
This can happen on a file that does not support multiple access. Some file types can only be opened in one program at a time. Running programs (including those in the background) should be verified. Sometimes it is necessary to wait a while before referencing the 1SP file again. 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.
