  • File Types: Certain file types may be blocked by your organization's policies or by Outlook itself for security reasons.
  • Network Issues: Poor internet connectivity can disrupt the sending or receiving of attachments.
  • Corrupted Files: Sometimes, the file itself may be corrupted, making it impossible to open.
  • Settings and Configuration: Incorrect settings in Outlook can also lead to attachment issues.
