Outlook Property Accessor error: The property "ttp://schemas.microsoft.com/mapi/proptag/0x7FFE000B" is unknown or cannot be found

I'm using the Outlook property accessor to email attachments. This is the Code that I'm using:

 //check whether attachments are there or not
                            if (mailItem.Attachments.Count > 0)
                            {
                                //loop through all attachments
                                for (int j = 1; j <= mailItem.Attachments.Count; j++)
                                {
                                    //check if attachment is email attachment, then only save to local directory
                                    if (mailItem.Attachments[j].PropertyAccessor.GetProperty("http://schemas.microsoft.com/mapi/proptag/0x7FFE000B") == false)
                                    {
                                        //save email attachment to local directory
                                        mailItem.Attachments[j].SaveAsFile
                                            (attachmentPath + "\\" +
                                            mailItem.Attachments[j].FileName);
                                    }
                                }
                            }

It's reading fine for most of the emails, but for a couple of them, I get this error:

The property "ttp://schemas.microsoft.com/mapi/proptag/0x7FFE000B" is unknown or cannot be found.

I want to know what's the fix for this error and if there are any workarounds if the error is thrown?

It is not the required property for attachments, i.e. not all attachments will have that property set.

The DASL property name corresponds to the PR_ATTACHMENT_HIDDEN property tag. It indicates whether an attachment is hidden from the end user.
