Therefore, you should understand the attached file and install a program that supports it.

  • File Type Associated With Wrong Program

This also means that the program has problems. In this case, you can save the file attachment, right-click the file, and choose another program to open it.

  • Data Compression

  • This error occurs when the subfolder containing the instance of Temporary Internet Files has reached its storage limit.
  • Because of the default security protocol, Outlook refuses to access suspicious information that can harm the user’s Outlook database or other system files. Therefore, Outlook attachments are automatically blocked with one of the above errors.
  • When a user tries to open Outlook attachments when the Outlook PST data file is damaged or inaccessible.
  • When the user re-enters the same Outlook connection. In this case, multiple temporary files with the same name are created in the temporary folder. Microsoft Outlook refuses to save temporary files with the same name to a temporary location after some time.
