Internal email undeliverable due to "Corrupt message content"

Hi All,

We have an issue with a user where an internal email cannot be delivered. The email reaches everyone else's mailbox except for 1 user. I checked the mail flow rules and there's nothing there that would indicate the email being blocked. Does anyone know how this situation can be fixed? I checked multiple forums but its all inconclusive.

Here is the error message:

Reason: [{LED=554 5.6.0 Corrupt message content; STOREDRV.Deliver.Exception:ConversionFailedException.ConversionFailedException; Failed to process message due to a permanent exception with message [BeginDiagnosticData]CorruptContent ConversionFailedException: CorruptContent[EndDiagnosticData] [Stage: PromoteCreateReplay]};{MSG

Thanks

-Phil
