Before I start a case I wanted to throw out the error here to see if anyone has seen it before. 

We have an email archive profile setup to bring in emails and attachments separately.  Its been working and still works, but recently they have noticed that emails sometimes do not make it in.  Or the email makes it but not the attachment.  This is for an invoice process so the attachment is an invoice.

Workflow takes the email and routes it to a folder and takes the attachment and routes it for coding.  I have searched Laserfiche and found the email but no attachment.  Sometimes neither.

Just looking for some direction on what the error means as invoices are being missed since LF is importing some but not others
