Notes about the OND file extension:
Incorrect file associations could be the result of underlying issues within your PC system. As such it is highly recommended to scan your PC for invalid registry entries, unused processes and other unfavourable system settings to identify slowdown issues.
The OND file type is primarily associated with 'Notes' by IBM. This was a Lotus product. Lotus was bought out by IBM. Lotus Notes and Domino are a fundamental component of IBM Workplace. An OND file is actually a small Notes database with only one document in it (OND=One Note Database). To open it, save the attachment and open it with a Notes client to see the message. If it's encrypted, you must be the intended recipient.
